Description

Technical Field

[0001] The present invention relates to the technical field of biological electrical signal measurement, and in particular to a wearable device for measuring biological electrical signals. Background Art

[0002] With the development of science and technology, a large number of biological monitoring devices are applied to life, such as electromyographic devices and electrocardiographic devices. Taking the measurement of heart rate as an example, two electrodes located at the proximal end and the distal end are generally set to obtain the voltage change of the heart. Since the human heartbeat has regularity, the heart rate can be calculated by identifying its characteristics. When the weather is dry, such as in winter, the friction between the wearer's clothes, the friction between the clothes and the detection device, and the friction between the clothes and the dry skin will generate static electricity. A large amount of static electricity and the discharge between static electricity may affect the current signal on the electrode sheet and interfere with the work of the working module in the head, thereby affecting the normal measurement of the biological monitoring device and reducing the accuracy and precision of the obtained data. Therefore, an innovative biological monitoring device is needed to prevent external electric or magnetic field interference during measurement to ensure accurate measurement.

[0003] After searching, the patent application with Chinese publication number CN221807974U discloses a heart rate measurement device, which is provided with a first conductive fiber cloth on the side of the heart rate head facing the body, so that one end of the first conductive fiber cloth contacts the skin at the proximal end and the other end contacts the skin at the distal end, the electrode sheet is insulated from the first conductive fiber cloth, and the connector passes through the first conductive fiber cloth and is insulated from it, thereby forming a first electrical circuit with the human skin, and the beating of the heart causes microcurrent to be generated in the first electrical circuit, so that at least in one dimension, the provision of the first conductive fiber cloth can prevent or reduce the interference of the external electric field and the external magnetic field on the electrode sheet, thereby reducing the probability of data measurement errors of the heart rate measurement device. By providing a third conductor between the connector and the heart rate head, the interference of the external electric field and the external magnetic field on the connector and the connector configuration in the third conductor is reduced.

[0004] However, when the external interfering magnetic field is too strong, for example, when the wearer wears more than two pieces of clothing containing polyester fibers for running, cycling and other sports in winter, a large amount of static electricity is generated and released due to intense exercise and dry weather. At this time, the strong external magnetic field makes it impossible for the first conductive fiber cloth to ensure the normal operation of the electrode sheet.

[0005] Therefore, the present invention proposes a wearable device for measuring electrical signals of a biological body. Summary of the invention

DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention;

[0042] For the convenience of description, in this description, when a user wears or puts on a wearable device, the side closer to the user's skin is the inner side, and the opposite side is the outer side;

[0043] Reference Figure 1-14A wearable device for measuring electrical signals of a biological body, comprising a wearable body 100; the wearable body 100 is a device for directing an electrode sheet 2 toward the skin of a biological body, and the wearable body 100 can make the electrode sheet 2 attached to the skin of the biological body and physically contact with it for signal measurement. The electrode sheet 2 can also be measured in a non-contact manner, such as using inductance. The wearable body 100 includes but is not limited to tights, women's sports bras, socks, wrist guards, elastic webbing with magic buckles at both ends, and TPU films with self-adhesive stickers. In some schemes, such as the scheme with authorization announcement number CN218391077U, the wearable body 100 is two unconnected woven cloth belts, each of which is provided with an electrode sheet 2, and each is connected to a connector 6, and each woven cloth belt is provided with a magic buckle device at the other end, and can be worn on the body trunk by fastening the measuring device.

[0044] The working module 500 includes a circuit board or device configured to calculate biological data such as measuring electrocardiogram (ECG), heart rate, heart beat interval RRI, biological impedance, etc. Figure 1 The chest-strap heart rate belt is taken as an example of one of the scenarios in which the user wears it: the working module 500 is a heart rate head, which is installed on the outside of the wearable body 100. The heart rate head is usually electrically connected to the electrode sheet 2 through the connector 6 so that the heart rate head can obtain and process the biological signal collected by the electrode sheet 2 to obtain physiological data. The physiological data can be transmitted to a smart terminal device 800 such as a mobile phone, a computer, a cycling meter, and a sports watch through wireless or wired methods such as Bluetooth and cables for display.

[0045] External interference refers to the interference caused to the electrical signal on the electrode sheet 2 and the electrical circuit formed by the electrode sheet 2, including the interference caused by static electricity around the electrode sheet 2, including the existence, release, and generation of static electricity, as well as the electric field and magnetic field generated in the daily life environment, including but not limited to when electrical appliances are used.

[0046] The electrode sheet layer includes at least one electrode sheet 2. The electrode sheet 2 can collect biological electrical signals; the biological signals here are electrocardiographic signals, or electrical signals used to calculate heart rate and electrocardiogram. Generally, the electrode sheet layer includes at least two electrode sheets 2 arranged at intervals, and the two electrode sheets 2 transmit the obtained electrical signals to the working module. When the electrode sheet layer is provided with only one electrode sheet 2, the electrode sheet 2 contacts the proximal end or distal end skin of the wearer, and another electrode sheet contacts the distal end or proximal end skin of the wearer, and the electrical signals on the two electrode sheets are transmitted to the working module 500. It should be noted that the proximal end and the distal end are opposite, and are not limited to the left and right sides of the human chest, but can also be the left and right arms of the human body, etc. The electrode sheet 2 includes but is not limited to conductive rubber, AgCl-containing conductive coating, cloth woven from silver wire, conductive fiber cloth, alloy material and carbon fiber conductive strip, and the shape is not limited, and can be rectangular, circular, elliptical, etc.

[0047] A wearable device for measuring bioelectric signals further includes:

[0048] A first conductor 31 is disposed outside the electrode sheet layer and at least partially covers the electrode sheet layer, that is, at least covers a part of one of the electrode sheets 2 in the electrode sheet layer. The first conductor 31 does not directly contact the skin of the organism and can be attached to the inner side, outer side of the wearable body 100 or embedded in the wearable body 100. In some embodiments, generally all the electrode sheets 2 of its electrode sheet layer are covered to achieve the best effect. The first conductor 31 is electrically isolated from the electrode sheet 2. In common designs, the first conductor 31 is very close to the electrode sheet layer. The first conductor 31 can be attached to the outer or inner side of the wearable body 100 with TPU hot melt adhesive, or can be embedded in the wearable body 100. When the first conductor 31 is attached to the wearable body with hot melt adhesive, the first insulating cloth 4 may not be provided because the TPU hot melt adhesive can insulate the first conductor 31 from the electrode sheet 2. In some special designs, the first conductor 31 is relatively far from the electrode sheet 2, so the first conductor 31 is not required to be pasted on the wearable body with insulating glue. The materials of the first conductor 31 include but are not limited to conductive rubber, AgCl-containing conductive coating, cloth woven from silver wires, conductive fiber cloth, alloy materials, and carbon fiber conductive strips.

[0049] A second conductor 32 is disposed on the wearable body 100 and can be attached to the outer side, inner side of the wearable body 100 or embedded in the wearable body. When the second conductor 32 is attached to the inner or outer side of the wearable body 100, an insulating cloth can be provided between the second conductor 32 and the wearable body 100 to prevent the wearable body 100 from absorbing water and the like from affecting the second conductor 32. The position of the second conductor 32 is different from that of the first conductor 31. The first conductor 31 and the second conductor 32 can be on the same plane or can have a partially overlapping area. Usually, the second conductor 32 is not on the outer and inner sides corresponding to the area of the electrode layer. The second conductor 32 is configured to have at least two parts in contact with the skin of the organism, one part in contact with the skin near the heart end and the other part in contact with the skin far from the heart end. Due to the beating of the heart, there is an electric potential difference between the skin close to the heart and the skin far from the heart, which causes a micro current to be generated on the second conductor 32. The near heart end and the far heart end are relative and are not limited to the left and right sides of the human chest. Generally, it can be broadly considered as two different parts of the skin of the organism, and the two different parts have different electric potentials due to electrocardiac activity. Generally, an insulator is provided around the second conductor 32, such as coating insulating glue to prevent external conductors from interfering with it and thus affecting the electric signals on the electrode sheet 2. The materials of the second conductor 32 include but are not limited to conductive rubber, AgCl-containing conductive coating, cloth woven from silver wires, conductive fiber cloth, alloy materials, and carbon fiber conductive strips.

[0050] The first conductor 31 is coupled to the second conductor 32, and the first conductor 31 is electrically isolated from the second conductor 32. The second conductor 32 is electrically isolated from the electrode sheet layer. When static charge exists outside the electrode sheet 2, due to the presence of the first conductor 31, the static charge affects the first conductor 31 first relative to the electrode sheet 2. When the first conductor 31 is coupled to the second conductor 32, the potential on the first conductor 31 is relatively stable, thereby reducing interference with the electrical signal on the electrode sheet 2.

[0051] A filter device 5 is provided on the second conductor 32. The filter device 5 comprises at least two conductive components 5a, and electrode plates 5b close to each other and electrically isolated are respectively provided between the two conductive components 5a to form a capacitor. The capacitor has the functions of filtering and storing electric charge, thereby reducing the potential fluctuation on the second conductor 32 and further protecting the electric signal on the electrode sheet 2 from external electric field interference.

[0052] The third conductor 33 is provided to enhance the function of the capacitor. The material of the third conductor 33 includes but is not limited to conductive rubber, AgCl-containing conductive paint, cloth woven from silver threads, conductive fiber cloth, and carbon fiber conductive strips.

[0053] When the first insulating cloth 4 is arranged between the first conductor 31 and the electrode sheet 2, the first conductor 31 and the electrode sheet 2 can be insulated. Generally, the first insulating cloth 4 is arranged on the inner side of the wearable body 100, because the wearable body 100 is usually made of a water-absorbing material such as a clothing webbing. When the electrode sheet 2 is directly arranged on the wearable body 100, when the user sweats or swims, the signal on the electrode sheet 2 will be affected, so the first insulating cloth 4 can be used to isolate and insulate the wearable body 100 and the electrode sheet 2. The material of the first insulating cloth includes but is not limited to TPU film, silicone skin, polyester fiber, etc.

[0054] When the first insulating cloth 4 is provided with water-absorbing fibers, the water-absorbing fibers can be wetted in advance. The water-absorbing fibers have water-retaining properties and can increase the humidity around the electrode sheet 2 for a long time, thereby reducing the probability of static electricity generation. The electrode sheet 2 can be attached to the first insulating cloth 4 with an insulating TPU hot melt adhesive so that the water-absorbing fibers do not affect the electrode sheet 2. When the first insulating cloth 4 is arranged on the inner side of the wearable body 100, the water-absorbing fibers can also contact the wearer's skin, thereby moistening the skin, making it easier for the electrode sheet 2 to obtain electrical signals.

[0055] When the electrode sheet layer is provided with two electrode sheets 2, one electrode sheet 2 contacts the proximal skin of the wearer, and the other electrode sheet 2 contacts the distal skin. It should be noted that the proximal skin and the distal skin are opposite, for example, one electrode sheet 2 is provided on the left arm of the wearer, and the other electrode sheet 2 can be provided on the right arm. Taking the heart rate chest strap as an example, the wearable body 100 is an elastic cloth belt, and magic buckles are provided on both sides of the cloth belt so that the cloth belt can be worn around the body trunk. When worn, one electrode sheet 2 contacts the left skin of the wearer's chest, and the other electrode sheet 2 contacts the right skin of the wearer's chest. The two electrode sheets 2 are electrically isolated and are generally symmetrically arranged on the wearable device 100 at a certain distance. The electrical signals on the two electrode sheets 2 can be transmitted to the working module 500 by coupling or direct electrical connection. The working module 500 can process the electrical signals to obtain data such as electrocardiogram, heart rate, HRV, etc. The working module 500 is a common and commercially available device on the market, such as the BigRun Team heart rate sensor, the POLAR H10 heart rate machine head, etc.

[0056] The connector 6 is used to transmit the electrical signal on the electrode sheet 2 to the working module 500, and can be an electronic component for coupling or a conductor such as a wire, a metal object, etc. that can electrically connect the electrode sheet 2 and the working module 500. It should be noted that, in some embodiments, the connector 6 can fix the working module 500 on the wearable device 100, and the working module 500 is also provided with a connector configuration 61 connected to the connector 6. The connector 6 is not electrically connected to the first conductor 31 and the second conductor 32.

[0057] The number of connectors 6 is generally consistent with the number of electrode sheets 2 on the electrode layer. When the fourth conductor 34 is arranged around the connector 6, the fourth conductor 34 is made of a conductive material, including but not limited to a mesh cloth supported by copper wires, a graphene conductive cloth, and a wire. The fourth conductor 34 is generally insulated from the connector 6. When the fourth conductor 34 is arranged around the connector 6, the electrical signal on the connector 6 can be protected from external interference in at least one dimension.

[0058] The material of the second insulating cloth 8 includes but is not limited to TPU film, silicone rubber, and polyester fiber. The second insulating cloth 8 can play a decorative role. When the two electrode sheets 2 are close to each other, when sweat fills the space between the two electrode sheets, the second insulating cloth 8 can also prevent the two electrode sheets 2 from short-circuiting.

[0059] Embodiment 1:

[0060] like Figure 2 and 3, which is a schematic diagram of a conventional heart rate belt. An elastic cloth belt is taken as the wearable device 100, and hooks 101 and hook rings 102 are provided on both sides of the elastic cloth belt, so that the elastic cloth belt can be worn around the body trunk of the biological body. Two conductive rubbers of the same size are attached to the inner side of the elastic cloth belt, and the two conductive rubbers are two electrode sheets 2. The two conductive rubbers are symmetrically arranged and spaced a certain distance apart to form an electrode layer. A TPU film can be attached between the two conductive rubbers and the elastic cloth belt as a first insulating cloth 4 to prevent the elastic cloth belt from affecting the electrical signal on the electrode sheet 2 due to water absorption, sweat absorption, etc. The connector 6 is a metal four-in-one buckle, which is composed of a metal female buckle 6a and a metal base 6b. The metal base 6b is electrically connected to the electrode sheet 2, and then passes through the elastic cloth belt to connect to the metal female buckle 6a located on the outside of the wearable device 100. The working module 500 is a heart rate machine head, which is provided with two metal sub-buckles, that is, a connector configuration 61 that cooperates with the connector 6, and the two metal sub-buckles can be buckled with the two metal female buckles 6a. A TPU film is attached to the outside of the electrode sheet 2 as the second insulating cloth 8 to cover part of the electrode sheet 2 to prevent the two electrode sheets 2 from being too close to each other and short-circuited by sweat etc. The second insulating cloth 8 can also cover the metal base 6b to play a decorative role.

[0061] Figure 5 is a diagram showing the positional relationship between the first conductor 31 and the second conductor 32. Figure 5 It is a top view viewed from the outside to the inside of the wearable body 100. The first conductor 31 and the second conductor 32 are both arranged on the outside of the first insulating cloth 4.

[0062] It should be noted that Figure 5 The first insulating cloth 4 and the second insulating cloth 8 are not drawn. A conductive cloth is arranged outside the first insulating cloth 4, covering the two electrode sheets 2. The conductive cloth is a first conductor 31. A second conductor 32 is arranged outside the first insulating cloth 4 around the electrode sheet 2. The second conductor 32 is close to the first conductor 31 but does not contact it. Generally, the connector is far away from the second conductor 32 and will not contact it. Two holes can be arranged on the first conductor 31 so that the connector 6 does not contact it when passing through. Silicone glue can be filled in the holes to insulate the connector 6 from the first conductor 31.

[0063] Figure 6 1 is a positional relationship diagram between the second conductor 32 and the first insulating cloth 4, viewed from the inside to the outside of the wearable body 100. The first insulating cloth 4 partially covers the second conductor 32 and exposes both ends thereof. Figure 6 The first conductor 31 is completely covered by the first insulating cloth 4 and is not shown.

[0064] Embodiment 2:

[0065] like Figure 7The figure is a top view from the outside to the inside, and the first insulating cloth 4 and the second insulating cloth 8 are not marked. Different from the first embodiment, the first conductor 31 extends to both sides so that part of it is close to and overlaps with the second conductor 32. Insulating glue is provided on the overlapping part of the second conductor 32 and the first conductor 31.

[0066] Embodiment three:

[0067] like Figure 8 The embodiment 1 is different from the embodiment 1 in that a fourth conductor 34 is disposed on the periphery of the connector 6, and the fourth conductor 34 is an O-shaped copper gasket. An insulating colloid is also disposed between the fourth conductor 34 and the connector 6 to prevent the fourth conductor 34 from affecting the connector 6.

[0068] Embodiment 4:

[0069] like Fig. 9 It is shown that, different from the first embodiment, a filtering device 5 is connected to the second conductor 32. The filtering device is composed of two conductive components 5a, and the two conductive components 5a are respectively provided with electrode plates 5b at one end close to each other. A capacitor is formed between the electrode plates 5b. The first conductor 31 is coupled with the second conductor 32. When there is interference outside the first conductor 31, the interference is coupled to the second conductor 32 and affects the electrical signal on the second conductor 32. When the filtering device 5 is set, since the capacitor has the function of filtering and storing charge, the degree of interference is reduced, thereby further protecting the electrical signal on the electrode sheet 2. In this embodiment, the two conductive components 5a are wires wrapped with insulating glue, and the two conductive components 5a are close to each other at one end to form an electrode plate 5b. One of the conductive components 5a is electrically connected to the side of the proximal end of the second conductor 32, and the other conductive component 5a is electrically connected to the side of the distal end of the second conductor 32.

[0070] like Fig.10 As shown in FIG. 5 , a conductive strip can be attached between the electrode plates 5 b as the third conductor 33. The third conductor 33 is used to enhance the capacitance of the capacitor, thereby further protecting the electrical signal on the electrode sheet 2.

[0071] Embodiment five:

[0072] Reference Figure 11-Figure 12In another embodiment, different from the first embodiment, this embodiment has only one electrode sheet 2. A piece of cloth is selected, and a strip of conductive cloth is adhered to the inner side of the cloth skin with TPU hot melt adhesive as the first conductor 31, and a piece of TPU film is adhered to the inner side of the first conductor 31 as the first insulating cloth 4. The first insulating cloth 4 completely covers the first conductor 31. Then a square conductive cloth is adhered to the first insulating cloth 4 as the electrode sheet 2, and the first conductor 31 can completely cover the electrode sheet 2. Then a "U"-shaped conductive cloth is adhered to the first insulating cloth 4, the conductive cloth is hollow in the middle, and the electrode sheet 2 is located in the middle area. The "U"-shaped conductive cloth is the second conductor 32, and silicone glue is coated on the second conductor 32 so that part of the second conductor 32 is covered by the silicone glue, and the first insulating cloth 4 partially covers the second conductor 32 and exposes parts on both the left and right sides of the "U"-shaped conductive cloth. The connector 6 is composed of a metal female buckle 6a, a metal base 6b and a conductive wire 321 arranged on the metal female buckle 6a. The metal base 6b contacts the electrode sheet 2 and passes through the cloth to be electrically connected to the metal female buckle 6a. The metal female buckle 6a is located on the outside of the cloth. Adhesive tape is arranged on both sides of the cloth belt so that the upper device can be attached to the skin of the biological body. When the wearer is a human, the upper device is attached to the left side of the human chest, and the exposed parts on the left and right sides of the "Hui"-shaped conductive cloth are in contact with the human skin. Since the skin relatively close to the heart and the skin relatively far from the heart have a potential difference, a microcurrent is generated on the "Hui"-shaped conductive cloth. At this time, the electrode sheet 2 is also in contact with the wearer's skin. Another upper device is arranged on the right side of the human chest. The conductive wires 321 on the two metal female buckles 6a are connected to the working module 500, and the conductive wires are wrapped with insulating rubber. The working module 500 is an electrocardiograph.

[0073] Embodiment six:

[0074] Reference Figure 13-14 , which is different from the fifth embodiment, in this embodiment, there is a wire 320 electrically connecting two U-shaped conductive cloths, and the outer surface of the wire 320 is wrapped with insulating rubber. Since the two U-shaped conductive cloths are separated by a certain distance and have different electric potentials, a microcurrent is generated when the two U-shaped conductive cloths are electrically connected.

[0075] In this embodiment, a conductive wire is further provided around the conductive wire 321 on the metal female buckle 6a. The conductive wire is the fourth conductor 34, and a thin insulating rubber skin can be wrapped around the conductive wire.
