本发明涉及一种变形传感器,包括在柔性电极间夹置有离子导电性聚合物层的结构,其中通过变形在离子导电性聚合物层中生成不均匀的离子分布,籍此在电极间生成电位差。
Description
技术领域
本发明涉及一种能够检测变形的挠性变形传感器。
背景技术
基于离子聚合物的致动器(例如,离子导电性聚合物致动器、导电聚合物致动器或者碳纳米管致动器)的研究作为低电压驱动(数V以下)的软致动器的研究而一直积极地进行(专利文献1到3)。这些致动器构造成使得两个或更多个电极层经由至少一个用作绝缘层的离子导电层而连接在一起。通过在电极之间施加电压,基础的三层结构弯曲并用作致动器。
在专利文献4中,铁磁层由钴、镍等通过电镀形成在固体聚合物离子交换膜上,以通过磁场引起致动器的位移。
