Problems solved by technology

For example, some studies use piezoelectric materials to convert the mechanical energy of certain human organs into electrical energy for the normal operation of medical equipment implanted in the human body. However, the internal environment of the human body is complex, and this energy conversion method relying on its own mechanical energy is not stable.
The energy transmission distance of magnetic, acoustic, thermal and other energy fields is limited.

Abstract

The invention provides a manufacturing method of a flexible implantable power supply based on infrared light remote charging. Firstly, a micro-array structure is made on a pyroelectric thin film, then one layer of metal film is sputtered at one end of the upper and lower surfaces of the structured pyroelectric thin film, thus one side of a transparent electrode film is rested on the metal film, a copper conductive wire is fixed to the metal film by using a conductive silver paste, the preparation of the flexible implantable power supply is completed, then PDMS is dropped and smeared to the flexible implantable power supply such that the flexible implantable power supply is completely coated by a PDMS film, only the copper conductive wire is exposed, and the heating and curing are carried out. The flexible implantable power supply is connected to a circuit, infrared light irradiates the flexible implantable power supply to realize the conversion of optical energy to electric energy, and different light-heat-electricity conversion efficiencies are realized through controlling the intensity and frequence of infrared light irradiation. According to the method, the transmission distance of energy is increased, and the light-heat-electricity conversion efficiency is improved.
