The present invention relates to a smart wearable wristband equipped with electrical electrodes for non-invasive neurostimulation. More specifically, it concerns a wristband designed to stimulate the wrist nerves with low-frequency electrical impulses, thereby aiding in user relaxation. This work was supported by the Korea Medical Device Development Fund grant funded by the Korea government (the Ministry of Science and ICT, the Ministry of Trade, Industry and Energy, the Ministry of Health & Welfare, the Ministry of Food and Drug Safety) (Project Number 1711196543, RS-2023-00253560).
With the recent proliferation of smartphones and wearable devices, there has been increased attention on health metric measurement. Traditionally, these applications have primarily involved using accelerometer sensors to measure steps and activity levels, or heart rate sensors for monitoring cardiac rates. However, there has been a growing interest in leveraging ECG sensors to monitor medically significant indicators, including arrhythmia, blood pressure, and blood glucose levels.
To facilitate real-time monitoring of these vital signs, wearable devices are designed to be worn on the wrist and portable. By integrating with medical technology, these devices can utilize the measured vital signs to monitor or diagnose a user's physical condition.
Recent medical journals have reported that changes in vital signs, such as heart rate, occur when individuals experience stress or excitement. It has been demonstrated that these conditions can be quantified and managed by using the vital sign data collected from wristbands.
Additionally, recent advances in traditional Chinese medicine suggest that non-invasive electrical stimulation can stabilize vital signs under stress. Moreover, numerous efforts are underway to treat various conditions, including hypertension, using non-invasive electrical stimulation methods. These approaches for stress relief and other treatments could offer significant benefits if integrated into wearable devices, allowing for continuous verification of their effectiveness through vital sign monitoring. However, the inadequate technological development in wearable devices has hindered their practical implementation.
Furthermore, although many smart wristbands on the market are capable of analyzing stress and excitement through vital sign measurements, none include a device for delivering electrical stimulation. This necessitates the use of separate modules, leading to the inconvenience of carrying multiple devices.

As shown in
The main unit 100 may include a sensor part on the lower surface to measure the user's vital signs, and the sensor part enables the user's biometric information, stress state, and excitement state to be grasped.
The main unit 100 may have a communication module for communicating with an external smart device, a battery for supplying power, and a control module for diagnosing a user's condition and prescribing electrical stimulation based on information acquired through the sensor part, and, if necessary, the upper surface of the main unit 100 is formed as a display so that the operating status can be checked.
In addition, a plurality of control buttons 105 are provided on the side of the main unit 100 to control or operate the operation of the main unit 100, and a charging terminal or a wireless charging module is formed to supply external power to the battery.
It can be, but is not limited to, a rectangular shape, but can also be a circle or a square with rounded corners.
Furthermore, to ensure that the main unit 100 remains closely fitted to the wrist, stimulation band 200 and securing band 250 are attached to both sides of the main unit 100. Each band wraps around opposite sides of the wrist and then overlaps and secures together, effectively holding the main unit 100 in place on the wrist.
The stimulation band 200 may have pogo pins 211 formed thereon for engagement with the connection terminal 107 formed on one side of the main unit 100, and the pogo pins 211 are electrically connected to the main unit 100 by contacting the connection terminal 107, thereby enabling the main unit 100 to receive power from a battery formed inside the main unit 100.
Furthermore, the stimulation band 200 has a plurality of fastening holes 232 formed at regular intervals in the center from one end to the other end, and a loop-shaped fastening loop 240 is formed at the other end of the stimulation band 200 into which a securing band 250 can be inserted.
The fastening holes 232 are used to insert the fastening end 260 formed at the end of the securing band 250 to secure the securing band 250 to the top of the stimulation band 200, and the fastening loop 240 is used to allow the securing band 250 to be inserted inwardly so that the securing band 250 does not swing from side to side once it is engaged in the fastening hole 232.
The securing band 250 is attached on the other side of the main unit 100 and is used in conjunction with the stimulus band 200 to secure the main unit 100 closely to the wrist, and has a downwardly protruding fastening end 260 that can be inserted into the fastening hole 232 of the stimulation band 200 to keep the main unit 100 and the stimulation band 200 wrapped around the wrist.
In this case, the securing band 250 may be configured as the same as the stimulation band 200, if necessary, with the fastening loop 240 changed to the fastening end 260, in which case the stimulation portion 400 may also be positioned on the securing band 250 to provide electrical stimulation.
The stimulation portion 400 may be formed in the form of a ring that wraps around the outer surface of the stimulation band 200 so that it can be moved along the outer surface of the stimulation band 200 in one direction or the other, and the lower surface is formed to stimulate the nerve based on the power supplied from the stimulation band 200, so that the nerve can be stimulated according to the state of the user to relieve muscle tension by stimulating the nerve with electricity according to the state of stress or excitement.
As described herein, the Neiguan PC 6 and the JianShi PC 5 are acupuncture points located on the inner side of the arm (where the inner side refers to the direction of the palm of the hand). The Neiguan PC 6 is located approximately three fingers' breadth from the wrist crease (see
Meanwhile, the stimulation portion 400 can electrically stimulate the median nerve 1100 or ulnar nerve 1200 located below the Neiguan PC 6 or the JianShi PC 5 by passing current. By targeting these nerves, this invention can effectively help in managing hypertension and alleviating stress.
Furthermore, the stimulation portion 400 is designed to accommodate the end of the securing band 250 inserted through the fastening loop 240, thus preventing lateral movement of the securing band 250. Details on how the stimulation portion 400 stimulates the wrist nerves will be discussed later with reference to the attached
As depicted in
The FPCB 210 is further characterized by the housing 230, which is designed to bend or flex to fit the contour of the wrist. This flexibility allows the intensity and timing of the stimulation provided by the stimulation portion 400 to be adjusted based on the vital sign data collected by the main unit 100.
The stimulation portion 400 features a body 410 designed with openings at the front and back, allowing it to encircle and slide along the outer surface of the stimulation band 200. Additionally, a pair of electrode ends 420 are situated on either side of lower surface of the body 410. One side of these electrodes connects electrically to supply positive and negative power when inserted into the stimulation band 200, while the other side contacts the wrist to deliver electrical stimulation.
The stimulation band 200 is designed to connect to the battery in the main unit 100 shown in
The FPCB 210 is a substrate crafted from flexible material, designed to easily conform to the user's wrist shape. It integrates various electronic components that regulate the operation of the electrical stimulus based on signals from the control module.
At one end of the FPCB 210, multiple pogo pins 211 are installed to establish electrical connections with the connection terminals 107 on the main unit 100. Each pogo pin 211 is connected to a power lines 214 and a control line 215, both of which are integrated into the FPCB 210.
In the case of the power lines 214, the + and − electrode wires are separately formed to allow the stimulation portion 400 to apply electrical stimulation, and the control wire 215 can be used to control the intensity, stimulation time interval for electrical stimulation.
The FPCB 210 also has a plurality of through-holes 213 in the center from one end to the other, the through-holes 213 being formed to allow the fastening end 260 formed on the securing band 250 of
Both sides of the through-hole 213 are provided with a plurality of electrified holes 212 to which the power lines 214 of the + electrode and the power lines 214 of the − electrode are connected, respectively, and the electrified holes 212 are formed by a pair of + and − electrodes spaced apart from each other with respect to the through-hole 213.
In this case, the power lines 214 of the + electrode are connected to the through-hole 213 formed on one side of the through-hole 213, and the power lines 214 of the − electrode are connected to the through-hole 213 formed on the other side of the through-hole 213, so that the electrified holes 212 located on either side of the through-hole 213 can be fixed with either + or − poles.
Additionally, the FPCB 210 may be configured with a control circuit to receive a control signal from the main unit 100 through the control line 215 or to transmit the status of performing the electrical stimulation to the main unit 100, and to change the intensity, intensity, pattern, and position of the electrical stimulation based on the biometric information of the user determined from the main unit 100.
The fixture 220 is designed to encase the top of the pogo pins 211 formed on the FPCB 210, protecting them from external impacts. It also locks into the housing 230 when the FPCB 210 is inserted, preventing the FPCB 210 from detaching. Additionally, when the main unit 100 is connected to the FPCB 210, the fixture 220 ensures that the housing 230 remains securely attached to the main unit 100.
In essence, the fixture 220 is designed to fasten the FPCB 210 within the housing 230 and to secure the housing 230 to the main unit 100. The fastening mechanism can be a hook, snap fit, or screw connection.
The housing 230 features an opening on one side to allow the insertion of the FPCB 210. It is preferably made from an elastic synthetic resin material such as silicone or rubber. This material choice not only insulates against the effects of the electrodes but also minimizes the risk of inducing skin diseases upon contact with the skin.
The FPCB 210, which is inserted inside the housing 230, is also made of a flexible material that allows the substrate to bend, and the housing 230 is also formed of a synthetic resin material, which allows it to conform to the user's wrist.
The housing 230 features a connection hole 231 and a fastening hole 232, which align with the electrified holes 212 and the through hole 213 in the FPCB 210, exposing them to the exterior. This alignment allows the electrode end 420 on the stimulation portion 400 to contact the electrified holes 212 through the connection hole 231, enabling it to receive electricity.
The fastening holes 232 are designed to accommodate the fastening end 260 from the securing band 250 shown in
The other side of the housing 230 is also provided with a fastening loop 240 formed in the form of a ring into which the securing band 250 can be inserted, the fastening loop 240 being used to secure the left and right position of the securing band 250 when the fastening end 260 of the securing band 250 is inserted into the fastening hole 232.
The stimulation portion 400 contacts the skin on the user's wrist and administers low-frequency electrical stimulation to promote relaxation, reducing stress and excitability. Comprising a body 410 and an electrode end 420, the stimulation portion 400 also helps alleviate hypertension by electrically stimulating the median and ulnar nerves located beneath the Neiguan (PC6) and JianShi (PC5) acupoints.
The body 410 is made from a silicone ring that allows it to move along the outer surface of the housing 230 while insulating against electrical conduction. The electrode ends 420 are constructed as two separate components on the lower surface of the body 410.
Here, the two electrode ends 420 are formed to receive power by contacting the + and − poles of the electrified holes 212 formed on the FPCB 210, respectively, and based on the power received, the user's wrist can be electrically stimulated.
To facilitate the insertion of the electrode ends 420 through the connection holes 231 in the housing 230 to the electrified holes 212 on the FPCB 210, the electrode ends 420 are designed with one end elongated towards the interior of the body 410. The other end is shaped in a flattened form to prevent a foreign sensation when contacting the user's wrist.
The other end of the electrode ends 420 that contact the user's wrist is preferably protruding higher than the surface of the body 410 because if it is aligned with the lower surface of the body 410, the electrode ends 420 may not make contact with the skin of the wrist and no electrical stimulation may be applied.
When the electrode ends 420 are connected to the electrified holes 212, the electrode end 420 formed on one side are connected to the power line 214 of the + electrode, and the electrode end 420 formed on the other side is connected to the power line 214 of the electrode.
This configuration ensures that the two electrode ends 420, each connected to different electrodes on opposite sides, contact the user's wrist when energized. An electrical stimulus is then applied as current flows between these two electrode ends 420.
As shown in
The stimulation portion 400 is also characterized in that it is formed in a plurality to allow simultaneous stimulation at various locations on the wrist.
Because the stimulation portion 400 is ring-shaped, it can be freely moved along the outer surface of the stimulation band 200, allowing the stimulation portion 400 to be moved to the point or nerve location that needs to be stimulated and then electrically stimulated.
Since the stimulation portion 400 must be in communication with the stimulation band 200 to be powered, its range of movement is limited to the location of the connection hole 231 formed in the stimulation band 200, but there are substantially multiple electrified holes 212 from one end of the stimulation band 200 to the other end, so it can be moved to various locations to apply electrical stimulation.
The stimulation portion 400 can also be formed into multiple stimulation bands 200 to simultaneously apply electrical stimulation to various parts of the body according to the user's biometric information, thereby realizing the same effect as acupuncture points on various parts of the body from a Chinese medicine perspective.
When multiple stimulation portions 400 are formed, the FPCB 210 inside the stimulation band 200 may be formed to individually control the power supplied to each electrified hole 212, and such control may allow multiple stimulation portions 400 to be sequentially electrically stimulated according to symptoms.
Moreover, since the insertion points of the electrode ends 420 are determined by the electrified holes 212, the main unit 100 can also provide location information to the user. This enables targeting specific points for neurostimulation based on the biometric information gathered.
As discussed, a smart wearable wristband featuring an electrical electrode for non-invasive neurostimulation, as per this invention, can alleviate symptoms or conditions by applying electrical stimulation based on stress levels and excitability measured through biosignal monitoring. The device allows for the modification and adjustment of the electrical stimulation applied to the wrist. This enables the stimulation of various acupuncture points from the perspective of Chinese medicine. Additionally, its portability and integrated electrical stimulation module allow for easy application of stimulation outdoors, thereby helping to stabilize the user's vital signs.

The user terminal 500 transmits the user's physical information to the AI analysis server 600.
More specifically, the user terminal 500 communicates wirelessly (LTE/Wi-Fi/BLE, etc.) with the main unit 100 of wearable device to receive physical information transmitted from the wearable device.
Here, the physical information may include biometric information (vital signs) and activity information about the user. Specifically, the biometric information may include at least one of blood pressure, oxygen saturation, respiration, pulse, body temperature, and blood glucose.

Additionally, this unit is electrically connected to both the input unit 530 and the adjustment unit 540, and it forwards physical data from the wearable device to the AI analysis server 600.
Further, the smartphone communication unit 520 may receive Stimulation information transmitted from the AI analysis server 600. The stimulation information may include at least one of a stimulation waveform, a operation mode, a stimulation time, a vibration mode, a near-infrared irradiation mode, and a far-infrared irradiation mode.
Specifically, the stimulation waveforms can include: an R-wave (square wave) based at 13 Hz, ranging from 10 Hz to 100 Hz, known for its strong energy intensity and its vibratory stimulation effect on acupuncture points; a P-wave (triangle wave) based at 3 Hz, ranging from 3 Hz to 20 Hz, which has a lower energy intensity but a potent stimulation effect on acupuncture points; and an S-wave (sine wave) based at 20 Hz, ranging from 5 Hz to 100 Hz, which provides gentle stimulation and massages the areas around acupuncture points.
Additionally, the intensity of all stimulus waveforms can be adjusted in 10 steps, ranging from 2 mA to 13 mA, based on a human body resistance of 500Ω. Furthermore, the default intensity settings for each stimulus waveform are 1× for the P-wave, 2× for the R-wave, and 3× for the S-wave.
There are three modes of operation: sequential mode, which applies the stimulus waveform to the electrodes in rotation, fixed mode, which fixes the stimulus waveform for each electrode, and single mode, which applies the same stimulus waveform to all electrodes.
Specifically, sequential mode applies different stimulus waveforms to multiple electrode pairs and alters the stimulus waveform at time intervals shorter than the period of the lowest frequency among the multiple stimulus waveforms.
In addition, the fixed mode applies different stimulus waveforms to multiple electrode pairs and the stimulus waveform does not change while the multiple electrode pairs are activated.
On the other hand, the single mode applies the same stimulus waveform to multiple electrode pairs.
If the control unit 540 automatically controls the Stimulation information, the smartphone communication unit 520 transmits the Stimulation information to the hypertension and stress reliever 440.
The input unit 530 enables manual input of physical information by the user, and enables inquiry of body analysis information, blood pressure history information, and stimulation information.

Accordingly, the input unit 530 is electrically connected to the smartphone communication unit 520.
The adjustment unit 540 automatically or manually controls the Stimulation information transmitted from the smartphone communication unit 520 and transmits it to a smartphone receiving unit provided in the smartphone communication unit 520.
First, when the adjustment unit 540 automatically controls the Stimulation information, the adjustment unit 540 transmits the automatically controlled Stimulation information to the smartphone communication unit 520.
On the other hand, when the adjustment unit 540 manually controls the Stimulation information, the adjustment unit 540 adjusts the Stimulation information transmitted from the AI analysis server 600 and transmits the adjusted Stimulation information to the hypertension and stress reliever 440 while simultaneously operating the meditation audio unit 250. The adjustment unit 540 is electrically connected to the smartphone communication unit 520 and the meditation audio unit 550. The meditation audio unit 550 generates one of meditation music, meditation sounds, and white noise.
The hypertension and stress reliever 440, worn on at least part of the user's body, delivers one or more types of stimulation-electrical, vibrational, or light-to at least part of the user's body. This is in response to stimulation information received from the AI analysis server 600.
Here, photostimulation includes light irradiation using far infrared light and light irradiation using near infrared light.
For this purpose, the hypertension and stress reliever 440 may communicate wirelessly (LTE/Wi-Fi/BLE, etc.) with user terminal 500 or main unit 100 of the wearable device to the AI analysis server 600.
