IPMC是一种智能材料,可作为柔性驱动器/传感器使用。针对目前IPMC智能材料的机械电子特性,即IPMC被动产生一定的物理形变后会在其厚度方向上产生可观的微小电压的特性,设计了一种新型的基于IPMC智能材料的微型发电装置。该方法通过悬臂梁受力变形的原理设计了发电装置的结构,同时设计了一种新型的机械全桥整流法对IPMC产生的电流进行处理,通过这种整流法,可以对IPMC输出的电流进行无损耗的采集。最后采用Lab VIEW软件,对所产生的电压信号进行检测。本设计具有结构简单、实现容易、携带方便、可随时随地发电等特点。
IPMC is a kind of smart material promising for soft actuator/sensor. It has the mechano-electrical transaction properties. When subjected to deformation, IPMC can generate detective electrical signal. An in- novative IPMC-based micro powergenerating device was developed by applying the cantilever deformation theory. A novel mechanical full bridge rectifier circuit was proposed to harvest the electrical signal generated by IPMC without any loss. The electrical signal generated in the experimental results was analyzed and pro- cessed by the LabVIEW. This design has a variety of advantages, such as simple structure,easy implement, convenience to carry and complete flexibility for time and spot.
