摘要
能源危机越来越受到全世界各国的关注,人们试图采用各种技术将自然能量采集并转化为有效电能。本文利用压电陶瓷所具有的正压电效应,将脚踏机械能有效采集并转化为电能。考虑到压电陶瓷产生高电压低电流的特点,本文主要解决了电流不稳定,持续供电时间短的问题。同时从实际工程应用出发,设计了成本低能量采集与转化的发电系统,可加装在鞋底,供小型随身电子装置使用。也可装在行人及车辆较多的交通要道,获得广泛的应用。
Energy crisis is becoming a global hot issue.Different kinds of technology have been exploited to harvest nature energy and convert into electric power.A foot press energy harvesting and converting electric circuit was designed by using the piezoelectric effect of PMNT ceramic.Considering that piezoelectric ceramics can produce high voltage and low current,the paper mainly solved the problem that the current is unstable and the long-time power supply is unavailable.The engineering application such as lower cost has also been considered.The Energy harvesting and converting system can be stalled on the shoes to supply the power for mini electric devices,and may be laid on the road to collect the energy and convert into electric power when people and vehicles pressed the PMNT ceramics.
