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

A method for manufacturing a flexible implantable power supply based on infrared light remote charging. Firstly, a microarray structure is made on the pyroelectric film, and then a metal film is sputtered on one end of the upper and lower sides of the structured pyroelectric film. Prepare transparent electrode films on the upper and lower sides of the structured pyroelectric film, place one side of the transparent electrode film on the metal film, fix the copper wires on the metal film with conductive silver paste, and complete the preparation of the flexible implantable power supply. The PDMS is drip-coated on the flexible implantable power supply, so that the flexible implantable power supply is completely surrounded by the PDMS film, and only the copper wire is exposed, and then heated and cured; the flexible implantable power supply is connected to the circuit, and the infrared light is irradiated on the flexible implantable power supply. The built-in power supply realizes the conversion of light energy to electric energy, and realizes different light-to-heat-to-electricity conversion efficiencies by controlling the intensity and frequency of infrared light irradiation. The invention increases the energy transmission distance and improves the light-to-heat-to-electricity conversion efficiency .

Description

Technical field [0001] The invention belongs to the technical field of medical electronics, and particularly relates to a method for manufacturing a flexible implantable power supply based on infrared light remote charging. Background technique [0002] With the improvement of people's living standards, the demand for implantable medical equipment will increase. The ability of implantable devices to work stably in the body for a long time requires a reliable and efficient energy supply unit. Because of its special working environment and closely related to human life, the power supply of human implantable medical equipment has some special requirements. For example, miniaturization, long use time, flexibility, good sealing, and good biocompatibility with the human body. Among them, the long-term and stable supply of power is the most important thing. There are currently two main types of energy supply methods for implantable devices: implantable batteries and non-contact energ...
