本科生毕业设计（论文） 中文题目： 悬臂梁压电振子发电的研究 英文题目： Study on Cantilever Piezoelectric Vibrator Generating Electricity 院 系： 械电子工程学院 专 业： 电子科学与技术  摘 要 随着集成电路和便携式电子设备的应用日益广泛，以化学电池为其主要供能方式存在诸多弊端，如体积大，质量大，供能寿命有限，需要定期更换，以及由此所带来的材料浪费和环境污染等问题，不容忽视。尤其对于目前发展日益迅速的无线网络和嵌入式系统来说，电池供电的这种缺陷更为明显。而压电发电具有结构简单、不发热、无电磁干扰、无污染和易于实现机构的微小化、集成化等诸多优点，且能满足此类低耗能产品的供能需求，而成为目前研究的热点。本文采用理论分析和试验验证相结合的方式，对悬臂梁压电振子发电装置的制备工艺和方法、发电原理、能量转换、输出功率等进行了研究。 关键词：悬臂梁 压电振子 压电发电装置 ABSTRACT As integrated circuit and portable electronic devices are used more and more widely, chemical battery as their main power supply has been found many shortcomings that can not be ignored, such as big volume, heavy weight, limited power lifetime and regular replacement, and the material waste and environment pollution related to these problems. These shortcomings are more apparent, especially with the development of wireless network and embedded system. However, piezoelectric generator has no complex structure, no fever, no electromagnetic interference and no pollution, and it is easy to realize the miniaturization and integration. Besides, it can meet the power demand of low energy product. Thus, piezoelectric generator is becoming a hotpots research. This paper has adopted the way of combining theoretical analysis and experimental tests, and it has studied the fabrication processes and methods, electric-generation principle, power conversion and output power of cantilever piezoelectric vibrator.
