[0099] Embodiment one

[0100] Please refer to Figures 1 to 2The electrode 10 provided by the embodiment of the present application comprises an insulating gel sheet 11, at least two first conductive gel parts 12 and at least two second conductive gel parts 13, wherein the insulating gel sheet 11 has a first surface 1101 and a second surface 1102, and the first surface 1101 and the second surface 1102 are oppositely arranged; all the first conductive gel parts 12 are embedded in the insulating gel sheet 11 from the first surface 1101, and each first conductive gel part 12 has a first exposed surface 1201 exposed on the first surface 1101, while two adjacent first conductive gel parts 12 are arranged at intervals; all the second conductive gel parts 13 are embedded in the insulating gel sheet 11 from the second surface 1102, and each second conductive gel part 13 has a second exposed surface 1301 exposed on the second surface 1102, while two adjacent second conductive gel parts 13 are arranged at intervals; the at least two second conductive gel parts 13 are in one-to-one conductive connection with the at least two first conductive gel parts 12. The electrode 10 provided by the embodiment has the at least two first conductive gel parts 12 embedded in the first surface 1101, the at least two second conductive gel parts 13 embedded in the second surface 1102, each second conductive gel part 13 having the second exposed surface 1301 exposed on the second surface 1102, and the at least two second conductive gel parts 13 in one-to-one conductive connection with the at least two first conductive gel parts 12, so that the electrode 10 has at least two conductive areas 102 with intervals between each other on the second surface 1102, and the different conductive areas 102 can be controlled respectively when the electrode 10 is powered on, so as to realize different power-on effects of the non-conductive areas 102. When the electrode 10 is powered on for massage, different massage functions can be realized and precise massage on specific parts of a user can be realized. Moreover, the conductive areas 102 are formed by embedding the first conductive gel parts 12 and the second conductive gel parts 13 on the two side surfaces of the insulating gel sheet 11 respectively and making them in conductive connection, so that different conductive gels can be selected to form the first conductive gel parts 12 and the second conductive gel parts 13 according to different requirements, for example, the first conductive gel parts 12 can have a higher adhesive strength than the second conductive gel parts 13, or the first conductive gel parts 12 can have a drug factor beneficial to human body.

[0101] Please refer to Figure 2 and Figure 4 In some embodiments, the first conductive gel parts 12 and the second conductive gel parts 13 in conductive connection with each other are in contact connection.

[0102] That is, in some embodiments, among the first conductive gel part 12 and the second conductive gel part 13 which are in conductive connection with each other, the first conductive gel part 12 extends through the insulating gel sheet 11 from the first surface 1101 in the thickness direction of the insulating gel sheet 11, while the second conductive gel part 13 extends through the insulating gel sheet 11 from the second surface 1102 in the thickness direction of the insulating gel sheet 11, and the first conductive gel part 12 and the second conductive gel part 13 contact each other at a certain position inside the insulating gel sheet 11 to achieve conductive connection, so that when the electrode 10 is energized from the first conductive gel part 12, the current can be transmitted from the first conductive gel part 12 to the second conductive gel part 13.

[0103] In some embodiments, the first conductive gel part 12 and the second conductive gel part 13 which are in conductive connection with each other are oppositely arranged. Here, the oppositely arranged refers to that when the electrode 10 is cut along a direction parallel to the thickness direction of the insulating gel sheet 11, and the cut surface is observed, it can be seen that the first conductive gel part 12 extends through the insulating gel sheet 11 from the first surface 1101 along a straight line trajectory in the thickness direction of the insulating gel sheet 11, while the second conductive gel part 13 extends through the insulating gel sheet 11 from the second surface 1102 along a straight line trajectory in the thickness direction of the insulating gel sheet 11, and the first conductive gel part 12 and the second conductive gel part 13 are in conductive connection at the abutting position, so that the two are observed to be in the state of opposite arrangement on the cut surface.

[0104] Please refer to Figure 2 , Figure 3 and Figure 5 In some embodiments, the first conductive gel part 12 extends through the insulating gel sheet 11 from the first surface 1101 along an inclined trajectory or a curved trajectory and is in conductive connection with the second conductive gel part 13; or the second conductive gel part 13 extends through the insulating gel sheet 11 along an inclined trajectory or a curved trajectory and is in conductive connection with the first conductive gel part 12; or the first conductive gel part 12 extends through the insulating gel sheet 11 from the first surface 1101 along the direction of an inclined trajectory or a curved trajectory, and the second conductive gel part 13 also extends through the insulating gel sheet 11 along an inclined trajectory or a curved trajectory and is in conductive connection with the first conductive gel part 12 at a certain position inside the insulating gel sheet 11.

[0105] Please refer to Figure 6In some embodiments, the first conductive gel part 12 and the second conductive gel part 13 are partially misaligned with each other. The partial misalignment refers to that, when the electrode 10 is cut along a direction parallel to the thickness of the insulating gel sheet 11 and the cut surface is observed, it can be observed that the first conductive gel part 12 is partially connected with the second conductive gel part 13, while the rest of the first conductive gel part 12 and the rest of the second conductive gel part 13 are misaligned with each other. Alternatively, the plane formed by the projection of the first conductive gel part 12 on a reference plane and the plane formed by the projection of the second conductive gel part 13 on the reference plane partially overlap.

[0106] Please refer to any of the drawings in Figures 1 to 7 and Figure 14 In some embodiments, the first conductive gel part 12 has a higher adhesive strength than the second conductive gel part 13, so that the adhesive strength of the first surface 1101 is higher than that of the second surface 1102 when the electrode 10 is used, facilitating the fixation of the electrode 10. When the electrode 10 is used as the electrode 10 of the wearable massager 30, the first surface 1101 is connected with the device body, i.e., the first exposed surface 1201 of the first conductive gel part 12 and the first surface 1101 of the insulating gel sheet 11 are adhered to the device body, while the second surface 1102 is connected with the user, i.e., the second exposed surface 1301 of the second conductive gel part 13 and the second surface 1102 of the insulating gel sheet 11 are adhered to the user. When the wearable massager 30 is separated from the user, the electrode 10 is peeled off from the user at the adhered part, without falling off from the device body, effectively ensuring the reliability of the wearable massager 30.

[0107] In some embodiments, the adhesive strength of the first conductive gel part 12 is between 150 g / 25 mm and 200 g / 25 mm. In some embodiments, the adhesive strength of the second conductive gel part 13 is between 100 g / 25 mm and 150 g / 25 mm. In some embodiments, the adhesive strength of the first conductive gel part 12 is between 150 g / 25 mm and 200 g / 25 mm, and the adhesive strength of the second conductive gel part 13 is between 100 g / 25 mm and 150 g / 25 mm, and when the adhesive strength of the first conductive gel part 12 is 150 g / 25 mm, the adhesive strength of the second conductive gel part 13 is not 150 g / 25 mm. In some embodiments, the material of the first conductive gel part 12 is selected from any one of an acrylamide system, a sodium acrylate system, a polyvinyl alcohol system, etc. In some embodiments, the material of the second conductive gel part 13 is selected from any one of an acrylamide system, a sodium acrylate system, a polyvinyl alcohol system, etc.

[0108] Please refer to any of the drawings in Figure 7In some embodiments, the first conductive gel portion 12 extends to the second surface 1102 in the direction from the first surface 1101 to the second surface 1102 and has a third exposed surface 1202 exposed on the second surface 1102, and the area of the third exposed surface 1202 is smaller than the area of the second exposed surface 1301. Such a structure design can make the second exposed surface 1301 and the third exposed surface 1202 on the same side to improve the contact firmness of the electrode 10 with the device or the user in contact with the second surface 1102, while ensuring that the contact firmness of the device or the user in contact with the second surface 1102 and the contact firmness of the device or the user in contact with the first surface 1101 are not the same, because the electrode 10 has a stronger contact firmness when only the second exposed surface 1301 on the second surface 1102 than when both the second exposed surface 1301 and the third exposed surface 1202 are present. In some embodiments, the area of the third exposed surface 1202 is not only smaller than the area of the second exposed surface 1301 but also smaller than the area of the first exposed surface 1201. Such a structure design can not only ensure the contact firmness of the electrode 10 with the device or the user, but also ensure that the contact firmness of the first surface 1101 and the second surface 1102 are not the same, because the adhesive strength of the first conductive gel portion 12 is greater than the adhesive strength of the second conductive gel portion 13, and the area of the third exposed surface 1202 is smaller than the area of the first exposed surface 1201 and the area of the second exposed surface 1301, so the contact firmness of the first surface 1101 with the device or the user is greater than the contact firmness of the second surface 1102 with the device or the user.

[0109] See Figure 7In some embodiments, the second conductive gel portion 13 extends to the first surface 1101 in the direction from the second surface 1102 to the first surface 1101 and has a fourth exposed surface 1302 exposed on the first surface 1101, and the area of the fourth exposed surface 1302 is smaller than the area of the first exposed surface 1201. Such a structure design can make the first exposed surface 1201 and the fourth exposed surface 1302 located on the same side to improve the contact firmness of the second surface 1102 of the electrode 10 with the device or the user in contact with the second surface 1102, while ensuring that the contact firmness of the device or the user in contact with the second surface 1102 and the contact firmness of the device or the user in contact with the first surface 1101 are not the same, because the electrode 10 has a stronger contact firmness with respect to the first surface 1101 only having the first exposed surface 1201 than with respect to the first surface 1101 having both the first exposed surface 1201 and the fourth exposed surface 1302. In some embodiments, the area of the fourth exposed surface 1302 is not only smaller than the area of the first exposed surface 1201 but also smaller than the area of the second exposed surface 1301. Such a structure design can not only ensure the contact firmness of the electrode 10 with the device or the user but also ensure that the contact firmness of the first surface 1101 and the second surface 1102 are not the same, because the adhesive strength of the first conductive gel portion 12 is greater than the adhesive strength of the second conductive gel portion 13, and at the same time, the area of the fourth exposed surface 1302 is smaller than the area of the first exposed surface 1201 and smaller than the area of the second exposed surface 1301, so the firmness of the first surface 1101 in contact with the device or the user is greater than the firmness of the second surface 1102 in contact with the device or the user.

In some embodiments, the width (L1) of the second exposed surface 1301 sandwiched between two adjacent insulating regions 101 is between 20 mm and 30 mm, which is conducive to the function of using current to stimulate muscles to make reciprocating movements to achieve muscle movement (i.e., EMS function) through the second exposed surface 1301.

When the first exposed surface 1201 is a flat surface, the vertical distance between the first exposed surface 1201 and the first surface 1101 is 0.1mm to 0.8mm. When the first exposed surface 1201 is an arc-shaped surface, the distance between the part of the first exposed surface 1201 farthest from the first surface 1101 and the second surface 1102 is 0.1mm to 0.8mm. The distance between the first exposed surface 1201 and the first surface 1101 is designed to meet the requirements of the electrically conductive massage and effectively avoid the problem of short circuit caused by the connection between adjacent exposed surfaces.
