以風力為震動源之小型壓電發電器
指導老師:許世哲   組長:古佳正   組員:鄭士良
在能源運用越來越受重視的現在,若將乾淨的風力產生之振動運用壓電材料轉換成電力,期盼可成為另一種乾淨的電力產生方式。本專題運用壓電材料之正壓電效應來發電,將壓電片結合一有延展性之基底,將基底頂端黏上一磁鐵,再於風扇主軸上各放置一相吸相斥之磁鐵,運用風扇之轉動(模擬騎車時風扇之轉動)讓基底和主軸的磁鐵以每半週期形成一吸一斥的力使基底前後擺動,造成壓電片之彎曲,進而發電。
In this time where energy has become more and more important, by combining wind energy with piezoelectricity, we hope to find a new way of producing clean energy. In this project, we tape the piezoelectric material to an expandable metal plate and place a magnet at the end of the plate, and then we use a fan and put magnets on its axel. By placing one with the s pole facing out the other with the n pole facing out, this causes them to attract and repel the magnet on the metal base. Due to these forces the metal plate will vibrate causing the piezoelectric board to expand with it, thus producing electric currents.
我們決定將壓電陶瓷晶片和鞋子做結合。
