The sensor 1 is used to adhere to the skin surface of a muscle to change the resistance value of the sensor 1 itself corresponding to the expansion and contraction of the skin surface. The sensor 1 generates a sensing signal according to its own resistance value. Wherein, the skin surface may be near the surface of the thigh skin above the knee. Referring to FIG. 2 , which is a cross-sectional view of the first embodiment of the sensor 1 , in the embodiment, the sensor 1 is a flexible sensor, and the sensor 1 includes a a substrate layer 11 and a conductive layer 12, the conductive layer 12 is covered on the substrate layer 11, and the two sides of the conductive layer 12 can be electrically connected to an electrode 14, respectively. Substrate layer 11.

Wherein, the substrate layer 11 is made of a flexible substrate, for example, by a Artificial skin composition. In detail, the artificial skin is mainly composed of a semi-permeable membrane (for example, a polyurethane semipermeable membrane) and a colloid (for example, a hydrophilic colloid), and the colloid is preferably applied to the substrate layer 11 away from the conductive layer 12 . One surface 111, whereby the surface 111 can be attached to the skin of the human body via the gel, and has an effect of improving ease of use.

The conductive layer 12 is bonded to the substrate layer 11 by sputtering. Therefore, the conductive layer 12 can be made of a metal material having good ductility and conductivity (for example, gold, silver, copper or aluminum or tungsten). In the present embodiment, limited to the process requirements, the conductive layer 12 is preferably made of silver, gold, tungsten or aluminum. The electrode 14 can be any conductor material, and the invention is not limited thereto.

Referring to FIG. 3 , it is a cross-sectional view of the second embodiment of the sensor 1 , which is different from the first embodiment in that an intermediate is further disposed between the substrate layer 11 and the conductive layer 12 . Layer 13, the interposer 13 is preferably made of titanium, aluminum or chrome.

More specifically, the interposer 13 is bonded to the substrate layer 11 by sputtering, and the conductive layer 12 is bonded to the interposer 13 via sputtering. Thereby, the interposer 13 can effectively enhance the adhesion of the conductive layer 12 to the substrate layer 11 to prevent the conductive layer 12 from being peeled off or peeled off from the substrate layer 11, and has the function of maintaining the normal operation of the sensor 1. effect.
