Abstract

The invention provides an integrated active power supply flexible pressure sensor. The sensor comprises a sensing unit of a sandwich structure and a power unit which is arranged with the sensing unitin a cascading mode and is used for providing power for the sensing unit. The power unit is a zinc-air cell of the sandwich structure, and comprises an anode, a cathode and a gel electrolyte, whereinthe anode and the cathode are oppositely arranged, and the gel electrolyte is arranged between the cathode and the anode. The anode is a flexible zinc-containing electrode, and the cathode is a flexible air electrode. The sensing unit comprises a negative electrode, a positive electrode and conductive fiber paper or conductive woven cloth, wherein the negative electrode and the positive electrodeare arranged oppositely, and the conductive fiber paper or the conductive woven cloth are arranged between the positive electrode and the negative electrode. The sensing unit takes the flexible zinc-containing electrode of the power unit as the negative electrode. The integrated active power supply flexible pressure sensor realizes an integrated design of the power unit and the sensing unit, and can be applied to practical applications such as human physical health monitoring and the like.
