自发电无线鼠标的设计方案及工作原理

设计采用压电陶瓷等新型材料，利用等效替代法通过无线鼠标内置重力感应小球运动撞击按压压电陶瓷产生电能，并通过升压稳压电路产生平稳电流，存储在锂电池中代替干电池支持鼠标工作，通过模拟实验法对电路进行模拟性实验，利用试验比较法确定项目方案。设计后装置能够产生一定电能支持鼠标工作。采用自发电理念缓解大量使用干电池造成环境二次污染的问题，有利于实现社会可持续发展。

Wireless Mouse Spontaneous Electrical Design Scheme and Working Principle

In this paper, piezoelectric ceramics was used in the spontaneous electric wireless mouse and power is produced by the moving gravity sensitive ball to touch the piezoelectric ceramic and then through the boosted and stabilized circuit to produce current regulating circuit. The power is stored in a lithium battery to support mouse work. The project adopts the concept of spontaneous electric to avoid the excessive energy consumption caused by extensive use of dry cell and secondary pollution of the environment problem caused by the high number of waste dry battery, which is helpful to realize sustainable development of the society.
