Embodiments relate generally to miniaturized sensor components, and more particularly, to devices, systems, and methods for the measurement of parameters by miniaturized sensor components and the contactless transmission of measured parameters therefrom.
Parameter measurement is important in numerous fields, such as packaging, medical device, human or pet health monitoring, home automation, food storage, and so on. Parameters can include biological, chemical, electrical, electrochemical, or any other appropriate parameter, such as temperature, humidity, or chemical changes for food safety, among others. For example, in one particular health monitoring related example, certain diabetes blood sugar meters measure the amount of glucose in the blood of a user. Other monitors can determine the amount of lactate in a user's body, for example. Traditionally, parameter measurement and analysis such as those described requires a wired or plugged-in connection from the sensor to the evaluating device, thus leading to additional complexity and difficulty of use.
Additionally, the measurement of certain aforementioned parameters in packaging such as bottles, ampoules, blister packs, and other packaging, is traditionally done with measuring strips or small sample containers that can only be evaluated with manual and inaccurate color codes or with the aid of dedicated measuring instruments. Using color codes or color strips to determine a change in color often leads to subjective inaccuracies in interpretation. Alternatively, while using dedicated measuring instruments can provide higher accuracy and often avoids subjective interpretation errors, such instruments have additional cost and additional maintenance and storage. Due to the nature of these and other applications, the sensors monitoring or measuring the aforementioned parameters should be small, safe, accurate, and often disposable, which has traditionally been a problem to engineer and manufacture.
Therefore, there is a need for small, cost-effective, accurate, and contactless sensing devices and systems that provide very simple mounting on different objects for detecting and transmitting biological, chemical, electrical, electrochemical, and other parameters.
In an embodiment, a sensing device comprises at least one sensor configured to sense a characteristic as a data parameter, an integrated circuit electrically coupled to the at least one sensor, the integrated circuit comprising memory and configured to store the data parameter in the memory, and an antenna electrically coupled to the integrated circuit, wherein the at least one sensor, the integrated circuit, and the antenna are integrated into a unitary body, and wherein the antenna is configured to transmit the data parameter stored in the memory to a remote device upon contactless placement of the remote device within a range of the antenna.
In an embodiment, an intelligent sensing device system comprises a sensing device configured to be operably coupleable to a packaging container and including at least one sensor configured to sense a characteristic as a data parameter, and an antenna configured to transmit the data parameter, and a remote device configured to receive the data parameter from the antenna, the remote device further comprising a graphical user interface adapted to display the received data parameter.
In an embodiment, a method of measuring at least a parameter comprises providing at least a sensing device configured to be operably coupleable to a packaging container, providing at least a sensor configured to sense at least a characteristic proximate the packaging container as a data parameter, providing a memory to store the data parameter in the sensing device, and providing an antenna configured to transmit the stored data parameter from the sensing device to a remote device upon contactless placement of the remote device proximate the sensing device.
The invention may be more completely understood in consideration of the following detailed description of various embodiments of the invention in connection with the accompanying drawings, in which:
While the invention is amenable to various modifications and alternative forms, specifics thereof have been shown by way of example in the drawings and will be described in detail. It should be understood, however, that the intention is not to limit the invention to the particular embodiments described. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
Embodiments relate to intelligent sensing devices, systems, and methods for the measurement of a wide variety of parameters. In embodiments, “intelligent,” strip-type, and/or container-type, contactless disposable measuring elements have an integrated circuit for acquiring and transmitting sensor data in conjunction with at least one sensor for parameter measurement and an antenna for contactless data transmission to and optionally from a reading device, and optionally, energy transmission from a reading device such as a smartphone.
In embodiments, sensing devices are miniaturized or small in size or form factor in order to minimize any impact on sensing device placement or the mobility or functionality of the placed-on or in object. Sensing devices can be integrated seamlessly into existing behavior or living patterns such that sensing devices are easily applicable on various small, irregular, and/or resilient surfaces, in embodiments. Sensing devices can asynchronously or synchronously sense or monitor parameters and subsequently store and/or communicate the sensed parameters.
In embodiments, sensing devices can be evaluated or accessed contactlessly and wirelessly by a smartphone, tablet, PDA, or other suitable reading device. Therefore, sensing devices can be read or utilized with commonly available equipment. By placement of the reading device in the proximity of the sensing device, or vice-versa, data can be read and evaluated from the sensing device by the reading device, and/or data can be transmitted from the sensing device to the reading device. In embodiments, reading device software, such as mobile apps, can be utilized to further store, archive, evaluate, or compare the sensed data.
In embodiments, devices, systems, and methods can provide highly accurate measurement and evaluation without a dedicated instrument. In embodiments, the integration of intelligent, contactless sensors (sensor-based data acquisition and contactless data transmission, e.g. by radio-frequency identification (RFID) or near field communication (NFC)) in sample containers or measuring strips can be evaluated by smartphones, tablets or other reading devices with contactless functionality.
An intelligent measuring strip can also be embodied in or as a tablet blister pack. In such embodiments, a sensor device can be configured to measure the electrical resistance of a resistive line lead over all tablet positions, the resistance of which changes when tablets are removed from their respective blister pouches as a result of singular interruptions of the line, and whereby the number of tablets removed can be detected. Reliable manufacturer identification can also be determined in such embodiments. In still other embodiments, compliance information regarding dosage and/or timing can also be recorded by the sensor device.
In other embodiments, sensor devices can be integrated into containers such as bottles, boxes, cartons, ampoules, syringes, medical vials, IV bags, IV tubing, and other packaging. In embodiments, sensor devices can be integrated into similar packaging, such as business cards or credit cards. In other embodiments, sensor devices can be embedded or implanted in human or animal skin or bodies.

For example, as described above with respect to the remote devices including a GUI, the parameter data can be displayed graphically or textually on the GUI.

Moreover, elements described with respect to one embodiment can be implemented in other embodiments even when not described in such embodiments unless otherwise noted. Although a dependent claim may refer in the claims to a specific combination with one or more other claims, other embodiments can also include a combination of the dependent claim with the subject matter of each other dependent claim or a combination of one or more features with other dependent or independent claims. Such combinations are proposed herein unless it is stated that a specific combination is not intended. Furthermore, it is intended also to include features of a claim in any other independent claim even if this claim is not directly made dependent to the independent claim.
Any incorporation by reference of documents above is limited such that no subject matter is incorporated that is contrary to the explicit disclosure herein. Any incorporation by reference of documents above is further limited such that no claims included in the documents are incorporated by reference herein. Any incorporation by reference of documents above is yet further limited such that any definitions provided in the documents are not incorporated by reference herein unless expressly included herein.
For purposes of interpreting the claims for the present invention, it is expressly intended that the provisions of Section 112, sixth paragraph of 35 U.S.C. are not to be invoked unless the specific terms “means for” or “step for” are recited in a claim.
