Biocompatible miniature frictional generator

Abstract

The invention discloses a biocompatible miniature frictional generator. The biocompatible miniature frictional generator consists of an upper pole plate nylon 66 coating layer, an upper pole plate poly-L-lactic acid macromolecule pair frictional layer, a lower pole plate ethyl cellulose pair frictional layer and a lower pole plate nylon 66 coating layer, wherein an upper pole plate material is an insulation type plate material formed by poly-L-lactic acid, and electrons are easily obtained; a lower pole plate is an insulation type plate material formed by ethyl cellulose, and electrons are easily lost; patterns in different shapes are manufactured on contact interfaces of the upper and lower pole plates, the upper and lower pole plates are in tight contact in a concave-convex opposite manner to form an arc-shaped space, and the space is packaged by a biocompatible nylon 66 film. The biocompatible miniature frictional generator has the advantages that the miniature generator is simple in structure, small in size and easy to operate; after the generator is inserted in vivo, micro voltage and micro current are generated by extrusion friction such as organism exercise, external massage and vibration; the generator can serve as a power supply of miniature diagnosis and treatment equipment implanted in vivo, and is widely applied to the medical fields of diagnosis, quick treatment, organ regeneration and the like.

Description

technical field [0001] The invention relates to a micro power generation technology for converting mechanical energy into electric energy, in particular to a biocompatible micro friction generator. Background technique [0002] Static electrification is a very old phenomenon dating back to hundreds of BC when the ancient Greeks and ancient Chinese discovered that rubbed amber was able to attract small and light objects. However, due to its randomness and storage problems, it has been regarded as a useless energy source and has not been developed. In recent years, with the advancement of material preparation technology, it has become possible to collect and store "useless" energy in the environment, making it a source of energy for small electronic devices. The concept of triboelectric nanogenerators proposed by Professor Wang Zhonglin from the Georgia Institute of Technology provides a new way to alleviate the energy crisis. [0003] The research group of Professor Chen M...
