1、In the past decades, process, memory and communication technology have got rapid development.Compare that, power technology progress is slow.Energy desity has not been improved obviously.Sensor and interactive mesh

2、ed network has made great academic progress.Because meshed network incressing in quantity and shrinking in the size, It' s more strict demand on the size ,lifetime of power and energy desity.The traditional power supply

3、can not meet the demand the develop of meshed network.So new electricity supply technology research become very critical.Safe, low cost and theoretically no life limit self-supply power technology and methodology has att

4、racted more and more attentions by researchers.Mechanical energy is one type of widely exist in the environment.Vibrations exist in lots of environments.How to convert the mechanical energy supplied by vibration

5、 into electrical energy were being studied by scientists on and on in recent years.In this paper we present the research and developing situation of micro-vibration generate electricity technology home and abroard in cha

6、pter one.In chapter two we set forth the effect of demagnetization of high permeability material and displacement-permeability and physical mechanism.In chapter three we studied displacement-permeability in the heterotyp

7、e composition and electromagnetic effect by experiment, as well as theory analysis, also we retrospect the research and developing situation of electromagnetic effect home and abroard.In chapter four we dis

8、cussed displacement-permeability in heterotype material and micro-vibration generate electricity and its efficiency estimation.About micro-vibration generate electricity technology,we make a prospect on how to integrate

9、.Ferromagnetic vibrate generate electricity is a new methods of pro-environment producing electricity.The merit of ferromagnetic vibration power generation assembly lie in simple structure .We can achieve more devices co

10、nnected in series or parallel connected to produce higher voltages or higher current, It' s pollution free, long operating life, low cost, do without consuming natural resources.So it has wide practical value in reality.
