Abstract

The invention refers to a kind of minimal electric generator, which is mainly made up of a pair of MEMS variable capacitances, an electret, and the processing circuit. The MEMS variable capacitance is made up of a moving polar plate and two fixed polar plates. The moving polar plate is made up of four folded beams, a weight block, and the two groups of fork on the block. The fixed polar plate is made up of a group of forks. The two groups of forks on the moving polar plate and the forks on the two fixed polar plate form the variable capacitance. There sets a leading out electrode on the two fixed polar plates. The above mentioned electrode is connected to the processing circuit through the wire. The invention has a high integrity, no the change of the battery charging or fuel, has no emission, the lifespan is long, and the volume is small. it can be used as each kind of micro energy consumption sensor and executer, especially the plated device, distributed system in vibration environment.

Description

technical field [0001] The invention belongs to the technical field of micro power supplies, in particular to a micro generator. Background technique [0002] Micro power supply is one of the most important research directions of MEMS (Micro Electro Mechanical Systems, Micro Electro Mechanical Systems) technology development, and has become a key issue urgently to be studied and solved in this field. Important breakthroughs have been made in thermal effect generators, etc. However, in some implanted devices, distributed systems, wireless communications, transportation, etc., due to many problems such as battery charging or fuel replacement, and limited use conditions, it cannot meet Require. For this reason, it is an important subject that people expect to solve to study a kind of micro-power source that can be used for a long time by a micro-generator system (transducer) that converts energy in the external environment into electric energy.
