A kind of biological protein flexible nano triboelectric generator and its preparation method

Abstract

The invention provides a biological protein flexible nanometer friction electric generator and a preparation method thereof. The preparation method comprises the steps of preparing a biological protein solution; providing a raster template, coating the surface of the raster template with the biological protein solution, and performing drying and separating to obtain a biological protein membrane with a micro-nano raster structure on the single surface; adopting a human body implantable metal as a target material, and sputtering a friction electrode layer on the surface, without the raster structure, of the biological protein membrane; and performing cutting, taking the biological protein membrane as a first biological protein layer and a second biological protein layer, and taking the friction electrode layer as a first metal friction electrode layer and a second metal friction electrode layer to form the biological protein flexible nanometer friction electric generator. The electric generator disclosed in the invention is totally formed by human body degradable materials, so that immunoreaction is not caused after the electric generator is implanted into human body, without takingout through a secondary surgery; and through the raster structure, completeness and reflection strength of a reflective pattern can be checked, so that the output power of the electric generator canbe fed back in real time, and the degradation condition of the biological protein flexible nanometer friction electric generator can be monitored.

Description

technical field

[0001] The invention belongs to the technical field of implantable medical generators, in particular to a biological protein flexible nano friction generator and a preparation method thereof. Background technique

[0002] Harvesting energy from the living environment is widely regarded as an effective way to achieve green energy and sustainable energy development, and is expected to play an important role in the energy supply of wireless transmission systems, implanted medical devices, and even consumer electronics. Based on the principle of triboelectrification and electrostatic induction, the micro triboelectric generator prepared by simple and low-cost processing can complete the high-efficiency collection of mechanical energy in the surrounding environment, and achieve high output power density and energy conversion efficiency. In addition to the function of energy harvesting, due to the high sensitivity of the nano friction generator to the impact force,...
