Claim 16:
17. A piezoresistive sensor produced by the method of claim 3, wherein the method further comprises the steps of:
cutting the piezoresistive sensor material into a suitable size to obtain a hydrogel dielectric layer, comprising a sheet with a length of 1 cm to 3 cm, a width of 1 cm to 3 cm, and a thickness of 0.5 mm to 3 mm, or a sheet with a diameter of 1 cm to 3 cm and a thickness of 0.5 mm to 3 mm;
preparing an electrode hydrogel dielectric layer-electrode sandwich structure by using the hydrogel dielectric layer and electrode sheets, and drawing out a copper or silver wire with a diameter of 0.1 mm to 0.2 mm and a length of 6 cm to 15 cm as a lead wire on each of the electrode sheets to form a sandwich structure with lead wires; and
encapsulating the sandwich structure with lead wires using polyimide film tape to obtain a piezoresistive sensor.
