Technical Field

[0001] This invention relates to a physiological detection device, and more particularly to a skin electrical activity detection device with two electrodes arranged on a ring-shaped structure for contacting the skin of two different fingers. Background Technology

[0002] Current skin conductance detectors are installed on watches, with two electrodes for measuring signals fabricated simultaneously on the surface or back of the watch.

[0003] When the two electrodes are positioned on the surface, the user simultaneously contacts both electrodes with the palm of their non-wearing hand to perform measurements. This configuration is primarily for short-term measurements and is not suitable for long-term monitoring.

[0004] When the two electrodes are positioned on the back of the watch, they can continuously contact the skin of the wrist. However, due to the limited distribution of sweat lines on the wrist, the signal quality for detecting electrical activity of the skin is poor.

[0005] The information disclosed in the background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the relevant information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] In view of this, the present invention provides a ring-type physiological detection device for wearing on a user's finger to detect skin electrical activity.

The insulating region is disposed on the outer surface for electrically isolating the first electrode and the second electrode.

[0009] The present invention also provides a skin conductance activity detection device comprising a ring-shaped body, a first electrode, and a second electrode. The skin conductance activity detection device is worn on a user's finger. The ring-shaped body has an outer surface and an inner surface. The first electrode is disposed in a first region of the outer surface for contacting the user's first finger.

[0025] 100 Skin Conductivity Detection Device

[0026] 10 Detection Chips

[0027] ED1 First Electrode

[0028] ED2 Second Electrode

[0029] Seda detection signal

[0030] VRT, VRB voltage signals Detailed Implementation

[0031] One object of the present invention is to provide a ring-type detection device for continuous detection of skin electrical activity over a long period of time, which includes two electrodes for contacting two different fingers respectively, wherein the two different fingers may be fingers of the same hand or fingers of different hands, depending on the user's usage habits.

[0032] Please refer to Figure 1 This is a schematic diagram of an electrical activity of the skin (EDA) detection device 100 (hereinafter referred to as detection device 100) according to an embodiment of the present invention. Detection device 100 includes a first electrode ED1, a second electrode ED2, and a detection chip 15. The first electrode ED1 and the second electrode ED2 are used to contact the skin surface of different fingers of the user (which may be the same hand or different hands). Detection chip 15, such as an application-specific integrated circuit (ASIC), a digital digital processor (DSP), or a programmable gate array (FPGA), is used to provide different voltages to the first electrode ED1 and the second electrode ED2, and to measure the resistance change ΔRbody between the first electrode ED1 and the second electrode ED2. Detection chip 15 represents the detection chip of the following embodiment.

[0033] In one embodiment, to avoid polarization of the first electrode ED1 and the second electrode ED2, the detection chip 15 provides a first voltage VRT to the first electrode ED1 and a second voltage VRB, different from the first voltage VRT, to the second electrode ED2 during a first period t1, and provides the second voltage VRB to the first electrode ED1 and the first voltage VRT to the second electrode ED2 during a second period t2, wherein the length of the first period t1 may be equal to or different from the second period t2. In other words, the detection chip 15 alternately provides a high voltage (e.g., VRT) and a low voltage (e.g., VRB) to the first electrode ED1 and the second electrode ED2, respectively. The values ​​of the first voltage VRT and the second voltage VRB can be configured in advance based on voltages typically required for detecting electrical skin activity.

[0034] It is known that the skin resistance Rbody between the first electrode ED1 and the second electrode ED2 changes due to variations in sweat on the skin surface between the first electrode ED1 and the second electrode ED2, resulting in a resistance change ΔRbody, which can reflect skin electrical activity. In one embodiment, the detection chip 15 includes, for example, a transimpedance amplifier (TIA) for converting and amplifying the current signal into a voltage signal, thus the resistance change ΔRbody generates a voltage change ΔV. The detection chip 15 also includes, for example, an analog-to-digital converter (ADC) for generating a digital voltage signal. The detection chip 15 can detect skin electrical activity based on changes in this digital voltage signal. The method of detecting skin electrical activity based on the voltage change ΔV is known and will not be described in detail here.

[0035] In this invention, the detection chip 15 preferably also includes a wireless communication chip (e.g., an RF chip, a Bluetooth chip, but not limited thereto), for wirelessly transmitting the detection data Seda to an external electronic device 90, such as a smartphone or a smartwatch, but not limited thereto. Depending on the function of the detection chip 15, the detection data Seda may be a voltage change, a digital voltage value, or a result of skin conductance activity detection. The electronic device 90 performs predetermined control based on the received detection data Seda, which varies depending on the application.

[0036] Please refer to Figure 2A and Figure 2B As shown, Figure 2A This is a perspective view of the skin electrical activity detection device 200 according to the first embodiment of the present invention; Figure 2B This is a schematic diagram of the wearable application of the skin conductance activity detection device 200 according to the first embodiment of the present invention. The skin conductance activity detection device 200 (hereinafter referred to as the detection device 200) is worn on the user's finger and has a ring structure, including rings, finger sleeves, brass knuckles, etc., but is not limited thereto.

[0037] The detection device 200 includes a ring-shaped body 20, a first electrode 21, a second electrode 22, an insulating region 23, and a detection chip 25. The detection chip 25 is electrically coupled to the first electrode 21 and the second electrode 22 to provide a first voltage VRT and a second voltage VRB, and to detect the voltage change ΔV.

[0038] The annular body 20 has an outer surface and an inner surface (i.e., the surface that contacts the wearing finger). Figure 2A Although the location of the detection chip 25 is shown as being on the inner surface, this is for illustrative purposes only and not for limiting the invention. In one embodiment, the detection chip 25 may be concealed within the annular body 20 and not exposed on the surface.

[0039] A first electrode 21 is disposed in a first region of the outer surface for contacting a user's first finger, for example, finger F2. A second electrode 22 is disposed in a second region of the outer surface for contacting a user's second finger, for example, finger F3. An insulating region 23 is disposed on the outer surface for electrically isolating the first electrode 21 and the second electrode 22. The size of the insulating region 23 is not limited to... Figure 2A and Figure 2B As shown, there are no specific limitations as long as the first electrode 21 and the second electrode 22 can be electrically isolated. In one embodiment, the insulating region 23 may be configured to have different features (e.g., different color or containing predetermined markings) from the first electrode 21 and the second electrode 22, so that the user can wear the detection device 200 at a predetermined angle / direction with reference to it. For example, Figure 2A and Figure 2B In this embodiment, the upward orientation of the insulating area 23 indicates that the detection device 200 is being worn correctly.

[0040] It must be noted that, although Figure 2A The surface of the insulating region 23 has the same height and curvature as the surfaces of electrodes 21 and 22 (e.g., forming a smooth connection surface), but the invention is not limited thereto. In other embodiments, the surface of the insulating region 23 is configured to be higher or lower than the surfaces of electrodes 21 and 22 (e.g., forming the aforementioned different features).

[0041] It must be noted that, although Figure 2A and Figure 2B The surfaces of the first electrode 21 and the second electrode 22 are shown to be curved, but the invention is not limited thereto. In another embodiment, the surfaces of the first electrode 21 and the second electrode 22 are planar to facilitate contact with adjacent fingers of the wearing finger (e.g., shown as F1), for example, see reference. Figure 2CPlanes FS1 and FS2 are shown. By configuring the surfaces of the first electrode 21 and the second electrode 22 as planes, the user can easily wear the detection device 200 at a predetermined angle / direction. In another embodiment, the surfaces of the first electrode 21 and the second electrode 22 are respectively configured as concave surfaces or convex surfaces with a different curvature from the outer surface of the annular body.

[0042] In one embodiment, the first and second regions are positioned such that when the annular body 20 is worn on a user's predetermined finger F1 at a predetermined angle / direction, the first electrode 21 and the second electrode 22 respectively contact the adjacent fingers F2 and F3 on both sides of the predetermined finger F1. Figure 2B .

[0043] In another embodiment, the first and second regions are configured such that when the annular body 20 is worn on a user's predetermined finger F1 at a predetermined angle / direction, one of the first electrode 21 and the second electrode 22 (e.g., the first electrode 21) contacts one of the adjacent fingers on both sides of the predetermined finger F1 (e.g., F2), while the other of the first electrode 21 and the second electrode 22 (e.g., the second electrode 22) does not contact the other of the adjacent fingers on both sides of the predetermined finger F1 (e.g., F3). For example... Figure 2C When the annular body 20 is worn on the user's predetermined finger F1 at a predetermined angle / direction, the second electrode 22 is located on the upper side of the annular body 20 (at this time, it does not extend to the plane FS2), and therefore will not contact the finger F3. When the user wants to measure skin conductance, the user can touch the second electrode 22 with any finger of the non-wearing hand, so that the first electrode 21 and the second electrode 22 respectively contact the fingers of different hands.

[0044] In another embodiment, the outer surface of the annular body 20 has only a single plane, for example, FS1 is a plane while the FS2 side is changed to something else. Figure 2A The curved surface. In this embodiment, the second electrode 22 can Figure 2A or Figure 2C Configure the location.

[0045] In another embodiment, the first and second regions are positioned such that when the annular body 20 is worn on a user's predetermined finger F1 at a predetermined angle / direction, neither the first electrode 21 nor the second electrode 22 contacts the adjacent fingers on either side of the predetermined finger F1. In this embodiment, the user uses two fingers (unrestricted) of their other hand (the non-wearing hand) to contact the first electrode 21 and the second electrode 22 respectively for measurement.

[0046] For example, Figure 2D The display shows that when the annular body 20 is... Figure 2DWhen the ring body 20 is worn at an angle / direction on a user's intended finger F1, the first electrode 21 and the second electrode 22 are located on the upper (or lower) surface and the lower (or upper) surface of the ring body 20, respectively. In this embodiment, two insulating regions 23 are disposed on both sides of the intended finger F1 that contacts the ring body 20, adjacent to the fingers on both sides. The size of the first electrode 21 and the second electrode 22 is not specifically limited, as long as the ring body 20 is worn at an angle / direction on the user's intended finger F1. Figure 2D When the first electrode 21 and the second electrode 22 are worn at the user's intended finger F1 at the specified angle / direction, they should not come into contact with the adjacent fingers on both sides of the intended finger F1.

[0047] In another embodiment, both the first electrode 21 and the second electrode 22 are disposed only on the upper or lower surface of the annular body 20, and are electrically isolated from each other by the insulating region 23, similar to... Figure 2A As shown, the first electrode 21 and the second electrode 22 do not extend to the sides of the adjacent fingers of the predetermined finger F1 that contacts the annular body 20.

[0048] More specifically, in the first embodiment, both the first electrode 21 and the second electrode 22 are disposed on the outer surface of the annular body 20 and are electrically isolated from each other by an insulating region 23. The material of the insulating region 23 is not specifically limited.

[0049] It must be noted that, although Figure 2C The surface of the insulating region 23 has the same height and curvature as the surface of the second electrode 22 (e.g., forming a smooth connection surface), but the invention is not limited thereto. In other embodiments, the surface of the insulating region 23 is configured to be higher or lower than the surfaces of electrodes 21 and 22 (e.g., forming the aforementioned different features).

[0050] Please refer to Figure 3A and Figure 3B As shown, Figure 3A This is a perspective view of the skin electrical activity detection device 300 according to the second embodiment of the present invention; Figure 3B This is a schematic diagram of wearing the skin conductance activity detection device 300 according to the second embodiment of the present invention. The skin conductance activity detection device 300 (hereinafter referred to as the detection device 300) is worn on the user's finger and has a ring structure, including rings, finger sleeves, brass knuckles, etc., but is not limited thereto.

[0051] The detection device 300 includes a ring-shaped body 30, a first electrode 31, a second electrode 32, an insulating region 33, and a detection chip 35. The detection chip 35 is electrically coupled to the first electrode 31 and the second electrode 32 to provide a first voltage VRT and a second voltage VRB, and to detect the voltage change ΔV.

[0052] The annular body 30 has an outer surface and an inner surface. Figure 3AAlthough the location of the detection chip 35 is shown as being on the inner surface, this is for illustrative purposes only and not for limiting the invention. In one embodiment, the detection chip 35 may be concealed within the annular body 30 and not exposed on the surface.

[0053] A first electrode 31 is disposed in a first region of the outer surface for contacting a user's first finger, for example, finger F2. A second electrode 32 is disposed in a second region of the inner surface for contacting a user's second finger, for example, finger F1. The second region may cover part or all of the inner surface, without specific limitation.

[0054] An insulating region 33 is disposed in a region other than the first region on the outer surface to prevent the adjacent finger (not shown) on the other side of the second finger F1 from contacting the first electrode 31. Similarly, the insulating region 33 may be configured to have different features from the first electrode 31 (e.g., a different color or containing predetermined markings) so that the user can wear the detection device 300 in a predetermined direction / angle with reference to it. Similarly, there are no specific limitations on the material of the insulating region 33.

[0055] In one embodiment, the first region is positioned such that when the annular body 30 is worn on the user's second finger F1 at a predetermined angle / direction, the first electrode 31 contacts one of the adjacent fingers on both sides of the second finger F1 (e.g., F2) but does not contact the other of the adjacent fingers on both sides of the second finger F1. The surface of the first electrode 31 may be curved (e.g., Figure 3A ) or plane (e.g.) Figure 3C ).

[0056] In another embodiment, the first region is positioned such that when the annular body 30 is worn on the user's second finger F1 at a predetermined angle / direction, the first electrode 31 does not contact either of the adjacent fingers on either side of the second finger F1. For example Figure 3C As shown, when the annular body 30 is worn on the user's second finger F1 at a predetermined angle / direction, the first electrode 31 is positioned on the upper side of the annular body 30 (not extending to planes FS1 and FS2 at this time), so the first electrode 31 will not contact the fingers on both sides. When the user wants to perform a measurement, the user can contact the first electrode 31 with any finger of the non-wearing hand or other fingers of the wearing hand (if possible), so that the first electrode 31 and the second electrode 32 contact the fingers of different hands respectively. Alternatively, the user can rotate the annular body 30 to allow the first electrode 31 to contact one of the adjacent fingers on both sides of the worn finger F1, depending on the user's operating habits.

[0057] Similarly, in another embodiment, the outer surface of the annular body 30 has only a single plane, for example, FS1 (e.g., the side where the first electrode 31 is located) is plane while FS2 (e.g., the side where the first electrode 31 is not located) is changed to... Figure 3A The outer surface of the ring body 30 is a curved surface. That is, in the second embodiment, when the ring body 30 is worn on the user's second finger F1 at a predetermined angle / direction, the two opposite sides of the two adjacent fingers of the ring body 30 relative to the two sides of the second finger F1 are a plane or a curved surface.

[0058] Figure 3A The positions of the first electrode 31 and the insulating region 33 can be interchanged so that the first electrode 31 can be used to contact the finger (not shown) on the other side of the wearing finger F1.

[0059] In another embodiment, the first and second embodiments can be implemented in combination. For example, the skin conductance detection device of this invention may include three electrodes, such as 21, 22, and 32, see reference 1. Figure 2A , Figure 2C , Figure 3A , Figure 3C Two of the three electrodes may be located on the outer surface of the annular body of the skin conductance activity detection device, while one of the three electrodes may be located on the inner surface of the annular body. Two of the three electrodes are driven to perform measurements. For example, in a first time interval, electrodes 21 and 22 are driven to perform measurements, while in a second time interval, electrodes 21 (or 22) and 32 are driven to perform measurements. In one embodiment, the first and second time intervals are alternately configured, but this is not limited to this, and can be switched according to a prior configuration.

[0060] Please refer to Figure 4A and Figure 4B As shown, Figure 4A This is a perspective view of the skin electrical activity detection device 400 according to the third embodiment of the present invention; Figure 4B This is a schematic diagram of the wearable skin conductance activity detection device 400 according to the third embodiment of the present invention. The skin conductance activity detection device 400 (hereinafter referred to as the detection device 400) includes a first annular body 400A, a second annular body 400B, and a detection chip 45.

[0061] The first annular body 400A is for wearing on a user's first finger (e.g., shown as F2) and includes a first electrode 41 disposed on the inner surface of the first annular body 400A (e.g., ...). Figure 4A ) and outer surface (e.g. Figure 4C One of them is used to contact the user's first finger F2 or the finger adjacent to the first finger F2, which is not finger F1.

[0062] The second annular body 400B is for wearing on a user's second finger (e.g., shown as F1) and includes a second electrode 42 disposed on the inner surface of the second annular body 400B (e.g., ...). Figure 4A ) and outer surface (e.g. Figure 4C One of them is used to contact the user's second finger F1 or the finger adjacent to the second finger F1, which is not finger F2.

[0063] When the first electrode 41 is disposed on the outer surface of the first annular body 400A, the first electrode 41 is disposed on the opposite side of the second annular body 400B, for example... Figure 4C The FS1 side. When the second electrode 42 is disposed on the outer surface of the second annular body 400B, the second electrode 42 is disposed on the opposite side of the first annular body 400A, for example... Figure 4C The FS2 side. Similarly, in this embodiment, the surface of the first electrode 41 can be a plane or a curved surface; the surface of the second electrode 42 can be a plane or a curved surface.

[0064] When the first electrode 41 is disposed on the inner surface of the first annular body 400A, the first electrode 41 covers part or all of the inner surface of the first annular body 400A, as long as it has sufficient area to contact the wearer's hand. When the second electrode 42 is disposed on the inner surface of the second annular body 400B, the second electrode 42 covers part or all of the inner surface of the second annular body 400B, as long as it has sufficient area to contact the wearer's hand.

[0065] Figure 4D The first electrode 41 and the second electrode 42 are respectively disposed on the inner surface of the corresponding annular body and the other disposed on the outer surface of the corresponding annular body. Figure 4B In this design, the wearing fingers of the first annular body 400A and the second annular body 400B are interchangeable.

[0066] The detection chip 45 is electrically coupled to the first electrode 41 and the second electrode 42 to provide the first voltage VRT and the second voltage VRB, and to detect the voltage change ΔV on the skin surface.

[0067] In one embodiment, the detection device 400 further includes another chip 45' for operation in conjunction with the detection chip 45 (e.g., via wireless coupling). For example, when the detection chip 45 provides a first voltage VRT to the second electrode 42, the chip 45' provides a second voltage VRB to the first electrode 41, or vice versa. Either the detection chip 45 or the chip 45' detects a voltage change ΔV on the skin surface.

[0068] Similarly, in another embodiment, the detection chip 45 and chip 45' may be concealed within the annular body and not exposed on the surface.

[0069] Preferably, the first annular body 400A and the second annular body 400B are connected by an elastic member, and there are no specific restrictions on the material of the member.

[0070] It must be noted that although this invention is described using the example of electrodes contacting the skin of different fingers, the invention is not limited thereto. In other embodiments, the electrodes disposed on the outer surface of the annular body can be used to contact the skin of the palm, depending on the user's usage habits. Preferably, the two electrodes are not used to contact the skin of the same finger.

[0071] It must be noted that although this invention uses the detection chip to detect changes in skin voltage to detect skin electrical activity as an example, the invention is not limited to this. In other embodiments, the detection chip can be used to detect parameters such as skin resistance, conductance, admittance, and / or impedance to detect skin electrical activity. The methods for detecting skin electrical activity using these parameters are known and will not be described in detail here.

[0072] In summary, known skin conductance detectors configured in watches suffer from problems such as inability to perform continuous detection for extended periods or poor signal quality, depending on the electrode configuration. Therefore, this invention provides a ring-type skin conductance detection device (see reference). Figure 2A , Figure 3A and Figure 4A This device is worn on a user's finger to detect the voltage difference between two different fingers, thereby detecting electrodermal activity (EDA). Because the EDA device of this invention detects signals on the fingers, it offers better signal quality compared to detecting signals on the wrist. Furthermore, depending on the different placement of the two electrodes, it can be configured for both active and passive measurement scenarios. Finally, by selecting an appropriate size, the ring-shaped structure achieves high stability in contact with the skin, improving the accuracy of physiological data detection.

[0073] While the present invention has been disclosed through the foregoing examples, it is not intended to limit the invention. Anyone skilled in the art to which this invention pertains can make various modifications and alterations without departing from the spirit and scope of the invention. Therefore, the scope of protection of this invention shall be determined by the appended claims.
