离子聚合物-金属复合材料（IPMCs）是一种用于实现运动传感器和执行器的新兴材料。在前一种情况下，通过弯曲的IPMC膜的电压输出，而在后一种情况下，电压输入是能够引起的膜弯曲。虽然一些有趣的属性已被描述为这样的材料，很少有结果已经获得关于其characterization.In本文中，专门用于表征的IPMC作为运动传感器的系统。该系统是为了研究IPMC的反应，在一个大的频率范围内，机械弯曲刺激，在悬臂配置。IPMC条作为两个固定板之间的可移动电容板，在差分电容测量系统。IPMC的运动被转换成系统输出电压，而没有任何机械接触，而ad-hoc电子检测IPMC传感输出电压。IPMC表征系统的描述如下的IPMC行为作为传感器和执行器的简要介绍。然后，步骤致力于评估之间的关系的输入位移被迫被测试的IPMC和相应的IPMC的电压输出。(C)2005 Elsevier B.V保留所有权利。
Ionic polymer metal composites (IPMCs) are emerging materials used to realize motion sensors and actuators. In the former case by bending an IPMC membrane a voltage output is obtained, while in the latter case a voltage input is able to cause the membrane to bend.Although a number of interesting properties have been described for such materials, few results have been obtained regarding their characterization.In this paper a system devoted to the characterization of IPMCs as motion sensors is presented. The system was built in order to study the IPMC reaction, in a large range of frequencies, to a mechanical bending stimulus, in a cantilever configuration.An IPMC strip acts as the movable capacitive plate between two fixed plates, inside a differential capacitive measuring system. The motion of the IPMC is transduced into the system output voltage, without any mechanical contact, while ad-hoc electronics detect the IPMC sensing output voltage.A description of the IPMC characterization system follows a brief introduction to IPMC behaviour as sensors and actuators. Then, steps devoted to evaluation of the relationship between the input displacement forced to the IPMC being tested and the corresponding IPMC voltage output are derived.
