This paper describes a novel method of self-sensing Ion-conductive Polymer Metal Composite (IPMC) actuator. Unlike the previous self-sensing technique, the proposed principle is based on the electric charge of the IPMC itself, which is correlated with its curvature. At the normal state, IPMC is electrically charged, and the amount varies according to the status of IPMC. While it is operated as an actuator, it also gives position information in the form of the electric charge amount, which is utilized for fast and accurate position control. In order to get the bending status of the actuator, the instantaneous voltage of IPMC is measured during the open state for input signal. The uncomplicated system is constructed to verify if the developed method is effective for the selfsensing actuator and evaluated by the experimental basis. The way to actuate the IPMC with selfsensing is a supplying discrete signal as an input, and it is also evaluated experimentally. This research also represents relatively simple structure for both actuation and sensing, which is very important factor to be implemented as a controller circuit for various applications.

This paper presents a preliminary idea for sensing the deformation of ion-conductive polymer metal composite (IPMC) actuator based on current detection. This method is based on the principle that the impedance of the IPMC actuator is correlated to its bending curvature. Experimental results on the relationship between actuating voltage, current and deformation are presented. It is shown that there are phase differences among these three variables. And it is further shown that within a certain range of deformation, there is a correlation between the impedance and the deformation. The findings suggest it is possible to design a novel way to detect the output feedback of IPMC actuator.
