Abstract
Ionic polymer metal composites (IPMCs) are emerging materials used to realize motion sensors and actuators. In the former case by bending an IPMC membrane an electric signal is obtained, while in the latter case an electric input is able to cause the membrane to bend. Hence, it makes sense to investigate the opportunity to use IPMCs to build either actuators or sensors. Though a number of interesting properties have been described for such materials, few results have been obtained regarding their characterization. In this work, a new experimental setup to investigate IPMC behaviour as sensors is described and some results of the analysis of sensing properties of IPMCs strips are presented. In particular attention is focused on the influence of IPMC structure on the performance of the sensor and preliminary results concerning its life time are showsI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
