Kynar Pennwalt 公司用聚丙烯撑氟塑料代替压电陶瓷材料获得成功。这种材料是一种柔性高于陶瓷而容量较低的代用材料。在给定电压下,厚度相同时,其输出电压比压电陶瓷可高出一个数量级。这种器件可
Kynar Pennwalt succeeded in replacing the piezoelectric ceramic with polypropylene-based fluoroplastics. This material is a flexible alternative to ceramic and lower capacity alternative materials. At a given voltage, the same thickness, the output voltage than the piezoelectric ceramic can be an order of magnitude higher. This device can be
