Description

BACKGROUND

Field

The disclosure relates to an electronic device including multiple temperature sensors.

Description of Related Art

In general, electronic devices refer to device configured to perform specific functions according to installed programs, such as home appliances, electronic diaries, portable multimedia players, mobile communication terminals, tablet PCs, video/audio devices, desktop/laptop computers, and vehicle navigation systems. Such electronic devices may output stored information as sounds or images. In line with the high degree of integration of electronic devices and the widespread use of super-fast large-capacity wireless communication, it has recently become possible to equip a single mobile communication terminal with various functions. Not only a communication function, but also an entertainment function (for example, gaming), a multimedia function (for example, music/video playback), communication and security functions for mobile banking, a scheduling function, and an electronic wallet function may be integrated into a single electronic device.

Wearable electronic devices have been disclosed in various types, such as eyeglasses or watches, such that electronic devices can be mounted on human bodies and used. It has recently been requested to integrate various functions in wearable electronic devices, as in the case of mobile communication terminals.

A wearable electronic device may include at least one sensor for acquiring a user's biometric information, based on the fact that the same is mounted on a human body. For example, the wearable electronic device may include at least one sensor capable of acquiring biometric information such as the user's ECG, breathing, EMG, EOG, EEG, blood glucose, SpO2, PPG, or body temperature.

In connection with designing a wearable electronic device having a limited space to arrange components, it may be important to arrange various components in adequate positions. In addition, when a wearable electronic device is equipped with a sensor capable of acquiring biometric information, it may be critical to secure the reliability of the sensor through accurate calibration.

When mounted on a wearable electronic device as a sensor for acquiring the user's biometric information, a body temperature sensor may sense the user's body temperature while making close contact with the user's skin. According to the prior art, a contact-type body temperature sensor and a non-contact-type body temperature are disclosed as body temperature sensors mounted on wearable electronic devices. The contact-type body temperature sensor may measure the user's body temperature using a thermistor, the resistance of which is changed sensitively by a temperature change, for example. The non-contact-type body temperature sensor may detect thermal energy radiated from the skin, for example, using an infrared (IR) absorber, and may estimate the user's body temperature, based thereon, using the Stefan-boltzman formula.

The non-contact-type body temperature sensor may have a more complicated structure and a higher manufacturing cost than the contact-type body temperature sensor. The contact-type body temperature sensor may have a simpler structure and a lower manufacturing cost than the non-contact-type body temperature sensor, but is vulnerable to influences of external environments, and the measured body temperature result may thus be inaccurate.

In this case, the processor and/or the communication module may be mounted in the form of an integrated circuit chip, but it may not be limited thereto.

According to various embodiments, the electronic component 350 may be disposed on the main circuit board 360, and may include an antenna radiator and/or a wireless charging antenna. The antenna radiator may be configured to transmit and receive radio signals in a magnetic secure transmission (MST) method. For example, the antenna radiator may be an MST antenna. As another example, the antenna radiator may be a near field communication (NFC) antenna transmitting and receiving wireless signals in an NFC method. According to an embodiment, a shielding structure may be disposed around the antenna radiator to block signal interference between other electronic components. The wireless charging antenna may be attached to one surface of the main circuit board 360. The wireless charging antenna may be formed in the form of a flat coil. The wireless charging antenna may be made of a conductive material and may be electrically connected to the main circuit board 360. The wireless charging antenna may be configured to generate a current by electromagnetic induction generated from an external electronic device. The current generated in the wireless charging antenna may be configured to charge the battery (not shown) through the main circuit board 360.

According to various embodiments, the electronic device 300 may further include a heat dissipation structure (not shown). For example, the heat dissipation structure may be disposed between the main circuit board 360 and the battery 390. The heat dissipation structure may be configured receive heat generated in the main circuit board 360 to prevent and/or inhibit the main circuit board 360 from being overheated.

According to various embodiments, the second plate 315, which is configured to form a second surface 315a toward the second direction (the −Z-axis direction) of the housing 310, may include a penetration part 317 at least a portion of which is transparent. The second plate 315 may not be limited to being made of a glass material, and may be made of a transparent material such as transparent reinforced plastic. The second plate 315 may be configured to be in contact with a part (e.g., wrist) of the human body of a user. Referring to FIG. 3, the second plate 315 may have a center area formed as the penetration part 317, which is transparent (or translucent), for a sensing operation of the sensor 370, and the other areas (the peripheral area) other than the center area may be formed to be opaque. According to an embodiment, differently from what is illustrated in drawings, the entire area of the second plate 315 may also be formed to be transparent.

According to various embodiments, the sensor 370 may be disposed between the main circuit board 360 and the second plate 315 so as to sense biometric information of a user. For example, the sensor 370 may be a body temperature sensor for measuring a body temperature when a user wears the electronic device 300. The processor (e.g., the processor 120 of FIG. 1) may be configured to receive an electrical signal from the sensor 370 so as to calculate and determine the body temperature of a user. According to various embodiments, the sensor 370 may be a sensor, alternatively or additionally, further including another function (e.g., a heart rate measurement), in addition to measuring a body temperature. For example, a heart rate monitoring (HRM) device may be integrated into the sensor 370. The sensor 370 including a heart rate monitoring device may be configured to detect vasoconstriction/vasodilation by reflection of light according to a change in blood volume in blood vessels in the skin of a human body. In addition, various other embodiments may be applied to the sensor 370.

FIG. 4 is a diagram illustrating portions of an electronic device and a human body in order to show a body temperature measurement principle according to various embodiments.

An electronic device including a body temperature sensor S may be configured to measure the body temperature of a user in a state where a part B (e.g., wrist) of the human body of a user is in contact with a housing H of the electronic device. The body temperature sensor S may be disposed in the housing H of the electronic device, for example, on the inner surface of a plate configured to form the exterior of the housing H.

As illustrated in FIG. 4, when a body temperature of a user is measured using the body temperature sensor S, the temperature of a skin surface B1 of the user may be measured, but it may be difficult to measure the temperature of a deep part B2 spaced apart from the skin surface B1 of the user by a predetermined (e.g., specified) distance. In addition, the temperature of the skin surface B1 of the user may be affected by an external environment E. For example, since the temperature of the external environment E is very low in winter, when measured in the winter season, the temperature of the skin surface B1 of the user may be measured lower than the actual body temperature of the user.

Through the various example embodiments illustrated in FIGS. 5, 6, 7, 8, 9, 10 and FIG. 11 described in greater detail below, an electronic device and a body temperature measurement method capable of more accurate measuring a body temperature in various use environments will be described in greater detail.

FIG. 5 is a diagram illustrating an example internal structure of an electronic device including at least two temperature sensors according to various embodiments. FIG. 6 is a diagram illustrating a body temperature measurement principle according to a heat flow according to various embodiments.

Referring to FIG. 5, an electronic device 400 according to various embodiments of the disclosure may include a housing, a substrate, a processor, and at least two temperature sensors 500. In connection with the housing, the substrate, and/or the processor of the electronic device 400 illustrated in FIG. 5, descriptions of the housing (e.g., the housing 210 and 310 of FIG. 2 and FIG. 3), the substrate (e.g., the main circuit board 360 of FIG. 3), and/or the processor (e.g., the processor 120 of FIG. 1) according to the above-described embodiments may be referred to.

The at least two temperature sensors 500 may be arranged in the electronic device, and may include a contact-type temperature sensor 510 and a non-contact-type temperature sensor 520 arranged at different positions in the housing. Here, whether the ‘contact’ or the ‘con-contact’ may be determined according to whether the sensor can measure a temperature of an object-to-be-measured in a state of being in direct contact therewith or whether the sensor can measure a temperature thereof even in a state of being not in contact therewith. For example, the contact-type temperature sensor 510 may include a thermistor, and the non-contact-type temperature sensor 520 may include an infrared absorber. According to various embodiments, the at least two temperature sensors 500 may further include a third temperature sensor 530 provided separately. The third temperature sensor 530 may be a sensor for measuring a temperature of an external environment (e.g., the external environment E of FIG. 4), and may be additionally provided according to an embodiment. When the third temperature sensor 530 is provided, a body temperature of a user may be corrected based on a temperature of the external environment, which is measured by the third temperature sensor 530. According to various embodiments, in relation to the third temperature sensor 530, the contact-type temperature sensor 510 may be referred to as “the first temperature sensor 510”, and the non-contact-type temperature sensor 520 may be referred to as “the second temperature sensor 520”. In this case, it should be noted that the ‘ordinal number’ for each temperature sensor is only for distinguishing between temperature sensors and does not indicate the importance or the priority order of the temperature sensor.

According to various embodiments, the processor (e.g., the processor 120 of FIG. 1) may be configured to define (or decide) a body temperature of a user using the temperature data obtained using the at least two temperature sensors 500.

On the other hand, the processor (e.g., the processor 120 of FIG. 1) may be configured to measure a temperature of a first point P1 on the inner surface of the housing (e.g., a plate) using the contact-type temperature sensor 510, and may be configured to measure a temperature of a second point P2 on the outer surface of the housing (e.g., a plate) using the non-contact-type temperature sensor 520. A heat flow (heat flux) can be monitored using the measured temperature of the first point P1 and the measured temperature of the second point P2, and thus a body temperature of a user can be estimated through same.

FIG. 6 illustrates an example principle for a heat flow according to various embodiments of the disclosure. A total heat flow Q in the system may be the sum of a heat flow Q1 in a first object (e.g., the user's skin B) and a heat flow Q2 in a second object (e.g., the electronic device D). For example, the heat flow Q1 in the user's skin B may be proportional to the difference between a temperature value TS of the skin surface B1 and a temperature value TB of a deep part B2, the heat flow Q2 in the electronic device D may be proportional to the difference between a temperature value TD at the first point P1 and a temperature value at the second point P2 of the electronic device. In this case, the temperature value at the second point P2 of the electronic device may be approximated to the temperature value TS of the skin surface B1. When the temperature value TD at the first point P1 and the temperature value (e.g., the temperature value TS of the skin surface B1) at the second point P2 of the electronic device D are measured, it may be possible to estimate the heat flow Q2 of the electronic device D, and further it may be possible to estimate the value of the heat flow Q1 in the skin or to estimate a change amount thereof. According to various embodiments of the disclosure, when the temperature value TD at the first point P1 and the temperature value (the temperature value TS of the skin surface B1) at the second point P2 of the electronic device D are measured, it may be possible to estimate the heat flow Q2 of the electronic device D, and through same, the value of the heat flow Q1 in the skin or a change amount thereof may be estimated and thus a body temperature of a user may be defined. The measured temperature value TD at the first point P1 and the temperature value (the skin temperature value TS) at the second point P2 may be stored in a memory (e.g., the memory 130 of FIG. 1), and by accumulating same, it may be possible to derive a more accurate measurement result for a body temperature by reflecting same in the case where a body temperature is measured immediately on-demand.

Referring to FIG. 5 again, according to the electronic device 400 according to various embodiments of the disclosure, the processor (e.g., the processor 120 of FIG. 1) may be configured to monitor a heat flow using the contact-type temperature sensor 510 and the non-contact-type temperature sensor 520 as a pair. In this case, one of the pair of temperature sensors 510 and 520 may be disposed adjacent to a plate (e.g., the second plate 415 of FIG. 5) configured to form the exterior of the housing, and the other sensor may be positioned inside the housing. The ‘plate’ may be an element which is configured to form a part (e.g., the exterior) of the housing and has an inner surface on which at least one sensor is disposed. In the description of FIG. 5 and therebelow, although a second plate 415 is described as an example therefor, it may not be limited thereto. According to an embodiment, it should be noted that the ‘plate’ corresponds to another element (e.g., the first plate 311 or the bezel 320) other than the second plate 415.

In order to monitor the heat flow, the two sensors 510 and 520 included in the electronic device 400 may be disposed to be spaced apart from each other by a predetermined distance in the height direction (the Z-axis direction) of the electronic device. For example, as illustrated in FIG. 5, the contact-type temperature sensor 510 may be disposed on the inner surface 415b of the second plate 415, and the non-contact-type temperature sensor 520 may be disposed on the substrate 460. For example, a thermistor, which is an example of the contact-type temperature sensor 510, is disposed on the inner surface 415b of the second plate 415, and an infrared absorber as an example of the non-contact-type temperature sensor 520 may be disposed on the substrate 460. In this case, the contact-type temperature sensor 510 and the non-contact-type temperature sensor 520 may be arranged at positions which do not overlap each other in the height direction (the Z-axis direction) of the electronic device. According to an embodiment, the non-contact-type temperature sensor 520 may be disposed to be slightly spaced apart from the contact-type temperature sensor 510 in the height direction (the Z-axis direction) of the electronic device and may also be disposed to be spaced apart therefrom by a predetermined distance in the horizontal direction (e.g., the Y-axis direction), such that the non-contact-type temperature sensor and the contact-type temperature sensor do not overlap each other in the height direction (the Z-axis direction) of the electronic device.

Referring to FIG. 3 and FIG. 5 together, the electronic device 400 including the second plate 415 and the substrate 460 may be configured to have the penetration part 417 formed in the center of the second plate 415, and to have the non-contact-type temperature sensor 520 disposed in the height direction (the Z-axis direction) of the electronic device 400 from the penetration part 417. In addition, the contact-type temperature sensor 510 may be disposed on the inner surface 415b of the second plate 415, which surrounds the penetration part 417.

The processor (e.g., the processor 120 of FIG. 1) may be configured to measure a temperature of the first point P1 positioned on the inner surface 415b of the second plate 415 using the contact-type temperature sensor 510, and may be configured to measure a temperature of the second point P2 positioned on the outer surface 415a of the second plate 415 using the non-contact-type temperature sensor 520. In this case, the contact-type temperature sensor 510 may be configured to detect a temperature of an object-to-be-measured using the properties of heat conduction among various heat transfer methods, and the non-contact-type temperature sensor 520 may be configured to detect a temperature of an object-to-be-measured using the properties of heat radiation. According to an embodiment, the second point P2 may be positioned in the height direction (the Z-axis direction) of the electronic device from the first point P1 in the outer surface 415a of the second plate 415. That is, the processor (e.g., the processor 120 of FIG. 1) may be configured to measure a temperature of the outer surface 415a of the second plate 415, which is positioned in the height direction (the Z-axis direction) of the electronic device from the contact-type temperature sensor 510 using the non-contact-type temperature sensor 520. According to an embodiment, the non-contact-type temperature sensor 520 may include an infrared absorber, and using same, may be configured to detect thermal radiation energy of the second plate 415. According to an embodiment, the non-contact-type temperature sensor 520 may be configured to measure a temperature of a third point P3 on the penetration part 417 positioned in the height direction (the Z-axis direction) of the electronic device from the non-contact-type temperature sensor 520. In addition, according to an embodiment of the disclosure, the electronic device 400 may further include a pattern member 540, and thus the processor (e.g., the processor 120 of FIG. 1) may be configured to more easily measure a temperature of a point (e.g., the second point P2) which is not positioned on the non-contact-type temperature sensor 520 and in the height direction (the Z-axis direction) of the electronic device.

According to various embodiments, the pattern member 540 may be disposed on the inner surface 415b of the second plate 415 or the surface of the non-contact-type temperature sensor 520. In the embodiment of FIG. 5, it is illustrated that the pattern member 540 is disposed on the surface of the non-contact-type temperature sensor 520, for example, a surface 520a of the non-contact-type temperature sensor 520, which faces the second plate 415. The processor (e.g., the processor 120 of FIG. 1), using the non-contact-type temperature sensor 520 according to the embodiment illustrated in FIG. 5, may be configured to measure a temperature of a point (e.g., the third point P3) positioned in the height direction (the Z-axis direction) of the electronic device from the non-contact-type temperature sensor 520, and may be configured to more easily measure a temperature of a point (e.g., the second point P2) which is not positioned in the height direction (the Z-axis direction) of the electronic device. The processor (e.g., the processor 120 of FIG. 1), using the measured temperature of the first point P1 and the measured temperature of the second point P2, may be configured to monitor a heat flow Qa between the outer surface 415a and the inner surface 415b of the plate 415 and through same, may be configured to estimate a body temperature of a user. The processor (e.g., the processor 120 of FIG. 1) may also be configured to measure a temperature of a user using the non-contact-type temperature sensor 520 immediately on-demand. The contact-type temperature sensor has the characteristic of sensing thermal conductivity, and thus it takes time for the initial measurement thereof. Therefore, it may be disadvantageous in that the contact-type temperature sensor 510 immediately measures a body temperature. On the other hand, since the non-contact-type temperature sensor 520 can measure faster than the contact-type temperature sensor 510, a body temperature of a user can be measured immediately on-demand using the same. Referring to FIG. 5, the processor may be configured to determine a body temperature of a user, based on both accumulated data on the temperature estimated through the monitored heat flow Qa and the real-time temperature data of the third point P3, which is measured through the non-contact-type temperature sensor 520.

In FIG. 5, the distance of spacing between the inner surface 415b of the second plate 415 and the substrate 460 is merely conceptually or exaggeratedly illustrated for the convenience of explanation, and the actual distance of spacing may be shorter. For example, the distance of spacing between the inner surface 415b of the second plate 415 and the substrate 460 may be 0.5 mm to 5 mm. However, the distance of spacing may not be not limited thereto, and it may be variously configured according to various embodiments with respect to the shape or thickness of a housing of the electronic device 400, the internal structure of a housing, or the arrangement of components such as the arrangement of a substrate. In addition, although it appears that there is an empty space between the inner surface 415b of the second plate 415 and the substrate 460 in FIG. 5, according to an embodiment, various electronic components may be arranged inside the electronic device, and thus the empty space may not substantially exist.

FIG. 7 is a diagram illustrating an example pattern member 540 according to various embodiments.

According to an embodiment, the pattern member 540 may be applied when a non-contact-type temperature sensor (e.g., the non-contact-type temperature sensor 520 of FIG. 5) and a contact-type temperature sensor (e.g., the contact-type temperature sensor 510 of FIG. 5) are not arranged in the height direction (the Z-axis direction) of the electronic device and are arranged at positions having an angle with respect to the height direction of the electronic device.

Referring to FIG. 7, the pattern member 540 may include an open portion 540a in the center thereof and an inclined portion 540b around the open portion. The width a and the height b of the open portion 540a and the width c and height d of the inclined portion 540b may be variously applied according to an embodiment. For example, in various embodiments, the open portion 540a may be formed to have the width a of 100-300 μm and the height b of 10-30 μm, and the inclined portion 540b may be formed to have the width c of 10-30 μm and the height d 10-40 μm. According to an embodiment, the inclined portion 540b may be formed to have a cross section having a triangular pole shape, and angles e and f between the base and other sides adjacent to the base of the inclined portion 540b may be formed to have an angle of 20-50° and an angle of 60-85°, respectively. A non-contact-type temperature sensor (e.g., the non-contact-type temperature sensor 520 of FIG. 5) may be configured to detect thermal radiation energy of a heat source (e.g., the third point P3) positioned in the height direction (the Z-axis direction) of the electronic device through the open portion 540a in the center of the pattern member 540, and may be configured to detect thermal radiation energy of a heat source (e.g., the second point P2) not positioned in the height direction (the Z-axis direction) of the electronic device through the inclined portion 540b therearound. According to various embodiments, as the pattern member 540 includes the open portion 540a and the inclined portion 540b, if the pattern member is configured to easily measure thermal radiation energy in various directions, the pattern member may have any shape. For example, the pattern member 540 may be in the form of a film or in the form of a sheet, or may be formed to have the form of a lens.

FIG. 8 is a diagram illustrating an example internal structure of an electronic device including at least two temperature sensors according to various embodiments.

Referring to FIG. 8, the at least two temperature sensors 500 may be arranged in the electronic device, and may include a contact-type temperature sensor 510 and a non-contact-type temperature sensor 520 arranged at different positions in the housing. According to various embodiments, the processor (e.g., the processor 120 of FIG. 1) may be configured to define (or decide) a body temperature of a user using the temperature data obtained using the at least two temperature sensors 500.

The pattern member 540 may be disposed on the inner surface 415b of the second plate 415 or the surface 520a of the non-contact-type temperature sensor 520. In the embodiment of FIG. 8, an embodiment, in which the pattern member 540 is disposed on the inner surface 415b of the second plate 415, is illustrated. According to an embodiment, the pattern member 540 may be disposed on the inner surface 415b of the second plate 415, which is between the penetration part 417 and the non-contact-type temperature sensor 520. In the structure, the non-contact-type temperature sensor 520 may be configured to measure a temperature of a point (e.g., the third point P3) positioned in the height direction (the Z-axis direction) of the electronic device from the non-contact-type temperature sensor 520, and may also be configured to measure a temperature of a point (e.g., the second point P2) which is not positioned in the height direction (the Z-axis direction) of the electronic device.

The processor (e.g., the processor 120 of FIG. 1) may be configured to measure a temperature of the first point P1 positioned on the inner surface 415b of the second plate 415 using the contact-type temperature sensor 510, and may be configured to measure a temperature of the second point P2 positioned on the outer surface 415a of the second plate 415 using the non-contact-type temperature sensor 520. In addition, the processor (e.g., the processor 120 of FIG. 1), using the measured temperature of the first point P1 and the measured temperature of second point P2, may be configured to monitor the heat flow Qa in the housing, and may be configured to estimate a body temperature of a user.

FIG. 9 is a diagram illustrating an example internal structure of an electronic device including at least two temperature sensors according to various embodiments of the disclosure.

The embodiment illustrated in FIG. 9 may include a contact-type temperature sensor 510 and a non-contact-type temperature sensor 520 arranged at different positions in the housing.

As illustrated in FIG. 9, the electronic device 400 according to an embodiment may have the contact-type temperature sensor 510 disposed on the substrate 460 and the non-contact-type temperature sensor 520 disposed on the inner surface 415b of the second plate 415. For example, a thermistor may be disposed on the substrate 460, and an infrared absorber may be disposed on the inner surface 415b of the second plate 415. In this case, the contact-type temperature sensor 510 and the non-contact-type temperature sensor 520 may be arranged at positions which overlap each other in the height direction (the Z-axis direction) of the electronic device. The non-contact-type temperature sensor 520 and the contact-type temperature sensor 510 may be arranged at positions which overlap each other in the height direction (the Z-axis direction) of the electronic device and are slightly spaced apart in the height direction (the Z-axis direction). The distance of spacing between the inner surface 415b of the second plate 415 and the substrate 460 may be 0.5 mm to 5 mm, and in this case, the distance between the non-contact-type temperature sensor 520 and the contact-type temperature sensor 510 may be formed to be shorter than the distance of spacing between the inner surface 415b of the second plate 415 and the substrate 460. However, the distance of spacing may not be not limited thereto, and it may be variously configured according to various embodiments with respect to the shape or the thickness of a housing of the electronic device 400, the internal structure of a housing, or the arrangement of components such as the arrangement of a substrate.

A temperature of the first point P1 may be measured using the contact-type temperature sensor 510. In addition, a temperature of the second point P2 may be measured using the non-contact-type temperature sensor 520. In the embodiment of FIG. 9, the non-contact-type temperature sensor 520 may be disposed in the height direction (the Z-axis direction) of the electronic device from the second point P2, and thus a temperature of the second point P2, which spaced apart from the contact-type temperature sensor 510 in the height direction (Z-axis direction) of the electronic device, may be measured even without a separate pattern member (e.g., the pattern member 540 of FIG. 5 and FIG. 8).

The processor (e.g., the processor 120 of FIG. 1) may be configured to measure a temperature of the first point P1 inside the housing through the contact-type temperature sensor 510, and may be configured to measure a temperature of the second point P2 on the outer surface 415a of the second plate 415 through the non-contact-type temperature sensor 520. In addition, the processor (e.g., the processor 120 of FIG. 1), using the measured temperature of the first point P1 and the measured temperature of second point P2, may be configured to monitor a heat flow Qb, and through same, may be configured to estimate a body temperature of a user. According to various embodiments, the processor may also be configured to determine a body temperature of a user, based on both accumulated data on the temperature estimated through the monitoring of the heat flow Qb and the real-time data in which a temperature of the third point P3 is measured immediately on-demand through the non-contact-type temperature sensor 520.

FIG. 10 is a diagram illustrating an example internal structure of an electronic device including at least two temperature sensors according to various embodiments.

The embodiment illustrated in FIG. 10 may include a contact-type temperature sensor 510 and a non-contact-type temperature sensor 520 arranged at different positions in the housing.

According to an embodiment, as illustrated in FIG. 10, both the contact-type temperature sensor 510 and the non-contact-type temperature sensor 520 may be disposed on the substrate 460. For example, both a thermistor and an infrared absorber may be disposed on the substrate 460. In this case, the contact-type temperature sensor 510 and the non-contact-type temperature sensor 520 may be arranged at positions which are slightly spaced apart in the horizontal direction (e.g., the Y-axis direction) on the substrate 460.

The processor (e.g., the processor 120 of FIG. 1) may be configured to measure a temperature of the first point P1 inside the housing using the contact-type temperature sensor 510, and may be configured to measure a temperature of the second point P2 on the outer surface 415a of the second plate 415 using the non-contact-type temperature sensor 520. In addition, the processor (e.g., the processor 120 of FIG. 1), using the measured temperature of the first point P1 and the measured temperature of second point P2, may be configured to monitor a heat flow Qc in the housing, and may be configured to estimate a body temperature of a user. The electronic device 400 may further include the pattern member 540 disposed on the surface 520a of the non-contact-type temperature sensor 520, and thus may be configured to easily measure a temperature of a point (e.g., second point P2) which is not positioned on the non-contact-type temperature sensor 520 and on the Z-axis.

The processor (e.g., the processor 120 of FIG. 1) may be configured to measure a temperature of the first point P1 through the contact-type temperature sensor 510 and a temperature of the second point P2 through the non-contact-type temperature sensor 520, so as to monitor the heat flow Qc using the measured temperature of the first point P1 and the measured temperature of the second point P2, and through same, to estimate a body temperature of a user. According to various embodiments, the processor (e.g., the processor 120 of FIG. 1) may also be configured to determine a body temperature of a user, based on both accumulated data on the temperature estimated through the monitoring of the heat flow Qc and the real-time data in which a temperature of the third point P3 is measured immediately on-demand through the non-contact-type temperature sensor 520.

In the embodiment of FIG. 10, the distance between the first point P1 and the second point P2, which is the measurement standard for the distance of the heat flow Q, may be formed to be relatively long.

Accordingly, it may possible to more accurately measure a body temperature.

FIG. 11 is a perspective view showing the position of a third temperature sensor 530 according to various embodiments.

In the embodiments of FIG. 5, FIG. 8, FIG. 9, and FIG. 10 described above, an embodiment, in which the third temperature sensor 530 is disposed on a substrate 460, is shown. However, the position of the third temperature sensor 530 may not be limited to any specific arrangement. According to an embodiment, the third temperature sensor 530 may be disposed adjacent to the housing of the electronic device 400 so as to easily measure a temperature of the external environment E. For example, as illustrated in FIG. 11, the third temperature sensor 530 may be disposed at the lower end of an input device (e.g., a key or a button) positioned on the side surface of the electronic device 400. In addition, for example, the third temperature sensor 530 may be disposed adjacent to a side metal frame (e.g., the first plate 311 of FIG. 3) having high thermal conductivity in the electronic device 400. As described above, the third temperature sensor 530 may be configured to have various positions.

As described above, since the third temperature sensor 530 according to various embodiments may be provided, the processor (e.g., processor 120 of FIG. 1) may be configured to compensate the temperature measured using the contact-type temperature sensor 510 and the non-contact-type temperature sensor 520 and thus to more precisely define (or decide) a body temperature of a user.

The electronic device according to various embodiments may be one of various types of electronic devices. The electronic devices may include, for example, a portable communication device (e.g., a smartphone), a computer device, a portable multimedia device, a portable medical device, a camera, a wearable device, or a home appliance.
