Abstract

The invention discloses an organism medical disposable micro friction motor which comprises a conducting base plate a, an insulative high-molecular polymer layer which is accessible to electrons, a conducting base plate b, an insulative high-molecular polymer layer which is accessible to electrons and a middle contact interface between the insulative high-molecular polymer layers which are accessible to electrons. The middle contact interface is tightly contacted or forms an arc shape through patterns of different shapes in a concave-and-convex mode. The friction motor is fixed between a bone nain board board and a damaged tissue. Two conductive base plates (a, b) are connected with a positive electric potential in vivo treatment system, a negative electric potential in vivo treatment system and a in vitro detection system. The organism medical disposable micro friction motor and a manufacture method of the organism medical disposable micro friction motor have the advantages that the organism medical disposable micro friction motor is simple in structure, small in size, capable of generating micro voltage and currents through extrusion and friction such as body movement, external friction and vibration after the motor is built in a body and the motor can be built into the body and generates micro voltage through extrusion and friction such as body movement, external friction and vibration to promote growth of cells.

Description

【Technical field】 [0001] The invention relates to a micro power generation technology for converting mechanical energy into electric energy, in particular to a biomedical degradable micro friction generator and a preparation method thereof. 【Background technique】 [0002] In 2006, Wang Zhonglin's research group at Georgia College in the United States invented the nanogenerator for the first time. This kind of nanogenerator based on ZnO and other nanowire arrays with semiconductor properties and piezoelectric properties is used to drive microwatt-level electronic devices and solve the problem of tiny electronic devices. The problem of energy supply of equipment has opened up a new way, making piezoelectric electronics and nano energy devices a new research hotspot in the field of nanotechnology. In 2011, Professor Wang's research group invented a micro-generator based on the contact friction effect during the research process of the nano-generator, which greatly simplified th...
