In some embodiments, the plurality of electrodes 110 can be distributed irregularly, for example, more of the plurality of electrodes 110 can be concentrated in positions that are difficult to monitor or need to be focused on, and a smaller number of the plurality of electrodes 110 can be Spread out the distribution elsewhere. For the convenience of description, this specification will mainly introduce the electrode structure in which a plurality of electrodes are distributed in a rectangular array.

In some embodiments, as shown in FIG. 1 , the electrode structure 100 may further include a base 130, and a plurality of electrodes 110 may be respectively arranged on the base 130 along a first direction and a second direction. The two directions may have different deformable amounts respectively. In some embodiments, the electrode structure 100 has different elastic constants in the first direction and the second direction, so that the electrode structure 100 has different deformability in the first direction and the second direction. Specifically, the elastic coefficient of the electrode structure 100 in the first direction is the first elastic coefficient, and the elastic coefficient of the electrode structure 100 in the second direction is the second elastic coefficient. Wherein, the first direction is perpendicular to the second direction. In some embodiments, as shown in FIG. 1 , the number of electrodes 110 distributed along the first direction in each row of the electrode structure 100 may be the same as the number of electrodes 110 distributed along the second direction in each column of the electrode structure 100 . In some embodiments, the number of electrodes 110 distributed along the first direction in each row of the electrode structure 100 may be different from the number of electrodes 110 distributed along the second direction in each column of the electrode structure 100 . For example, the number of electrodes 110 distributed in each row along the first direction in the electrode structure 100 may be greater or smaller than the number of electrodes 110 distributed in each column in the electrode structure 100 along the second direction. In some embodiments, the base 130 can be made of flexible insulating material (eg, resin, soft PVC, silicone), and the shape can be rectangular, circular or other irregular shapes. In some embodiments, the electrodes 110 can be fixedly connected to the base 130 by means of pasting, clamping, welding and the like. In some embodiments, when the electrode structure 100 is applied to a wearable device, the substrate 130 may be a part of a wearable part (such as a jacket, trousers, belt, strap, etc.) worn by the user in the wearable device, or may be It is set separately from the wearing part, and then fixedly connected to the surface of the wearing part and the user's body by pasting, clipping, welding, etc., so that the electrode structure 100 can be fixed on the wearing part and attached to the user's skin to collect physiological data. Signal. In some embodiments, the deformable amount of the base 130 (or the deformable amount of the wearing part) can be consistent or substantially consistent with the deformable amount of the connecting member 120, so that when the user wears the wearable device, the electrode structure can be reduced. The uncomfortable feeling brought by the user and at the same time ensure that the position where the electrode structure 100 is arranged on the wearing part is not easily damaged. It should be noted that, in some embodiments, the electrode structure 100 may not include the base 130 , and each electrode 110 and one or more adjacent electrodes 110 may only be flexibly connected through the connector 120 .

In some embodiments, the electrode 110 may be a sheet structure, and the shape of the electrode 110 may be a regular shape such as a circle, an ellipse, a rectangle, a rhombus, or other irregular shapes.

The resistivity of the metal fabric electrode is smaller, and when the electrode structure 100 is used to fit human skin to collect physiological signals, the impedance of the metal fabric electrode and the contact impedance with the skin are also smaller. The smaller the thickness of the metal fabric electrode, the smaller its impedance and the contact impedance with the skin. In some embodiments, the smaller the contact impedance between the electrode 110 and the skin, the smaller the contact impedance between the electrode structure 100 and the skin, and the higher the intensity of the collected physiological signal. In some embodiments, when the metal fabric electrodes are used to collect physiological signals, the thickness of the metal fabric electrodes may be 500 μm˜2 mm. In some embodiments, the electrode 110 can also be an electrode formed by stacking different materials, such as an electrode composed of a metal fabric material and a conductive silicon material. Not only does it have a small contact resistance with the skin, but the conductive silicon in contact with the skin has Skin-friendly, washable and other advantages, avoiding the discomfort caused by the contact between the electrode and the skin.

In some embodiments, the first elastic coefficient of the electrode structure 100 in the first direction and/or the second elastic coefficient of the electrode structure 100 in the second direction can be adjusted by controlling the size of the electrode 110 to adjust the electrode structure 100 The amount of deformability in the first direction and/or the second direction. In some embodiments, the first elastic coefficient of the electrode structure 100 in the first direction and/or the electrode structure 100 in the second direction can be adjusted by controlling the ratio of the maximum dimension of the electrode 110 in the first direction to the maximum dimension in the second direction. The second elastic coefficient in the direction. In some embodiments, when the maximum dimension of the electrode 110 in the first direction is larger than the maximum dimension of the electrode 110 in the second direction, the first elastic coefficient of the electrode structure 100 in the first direction is smaller than that of the electrode structure 100 in the second direction. The second elastic constant, the deformable amount of the electrode structure 100 in the first direction is greater than the deformable amount of the electrode structure 100 in the second direction. In some embodiments, in order to make the electrode structure 100 have a certain amount of deformation in the first direction and/or the second direction, so as to improve the wearing comfort of the human body, the maximum size of the electrode 110 in the first direction and the second The ratio between the largest dimensions in the two directions may be 0.1-10.

In some embodiments, the ratio of the maximum size of the electrode 110 in the first direction to the maximum size of the second direction can be designed according to the elasticity requirements of the electrode structure 100 in the application scene, for example, the electrode structure 100 fits the human body The small deformability of the electrode structure 100 in the second direction has a significant effect on improving the comfort of the human body when the skin is attached, so the ratio of the maximum size of the electrode 110 in the first direction to the maximum size in the second direction can be designed bigger.

In some embodiments, the first elastic coefficient of the electrode structure 100 in the first direction can be adjusted by controlling the number and area of the electrodes 110 in the electrode structure 100 and the ratio of the total area of the electrode structure 100 to the sum of the areas of all electrodes 110 And/or the second elastic coefficient of the electrode structure 100 in the second direction, so as to adjust the deformable amount of the electrode structure 100 in the first direction and/or the second direction.

As an example, when the total area of the electrode structure 100 is constant, the smaller the area of the electrodes 110, the larger the distance between adjacent electrodes 110 may be. The greater the length (for example, the maximum dimension of the connecting piece 120 along the first direction or the maximum dimension of the connecting piece 120 along the second direction), the smaller the elastic coefficient of the connecting piece 120, and the smaller the deformable amount of the connecting piece 120.

In some embodiments, the greater the ratio of the area of the electrode structure 100 to the sum of the areas of all electrodes 110, the greater the first elastic coefficient of the electrode structure 100 in the first direction and/or the first elastic coefficient of the electrode structure 100 in the second direction. The smaller the two elastic coefficients are, the larger the deformable amount of the electrode structure 100 in the first direction and/or the second direction is. As an example, the larger the ratio of the area of the electrode structure 100 to the sum of the areas of all electrodes 110, the larger the distance between adjacent electrodes 110 may be, and the length of the connecting piece 120 connected between adjacent electrodes 110 (for example, the maximum dimension of the connecting piece 120 in the first direction or the maximum dimension of the connecting piece 120 in the second direction) is larger, the elastic coefficient of the connecting piece 120 is smaller, and the deformable amount of the connecting piece 120 is smaller. Larger, the greater the deformability of the electrode structure 100 in the first direction and/or the second direction.
