Paper Abstract

This paper presents a realization of a self-sensing ionic polymer-metal composite (IPMC) device by patterning its surface electrodes and thus creating separate actuator and sensor parts. The sensor and actuator elements of such device are still electrically coupled through the capacitance and/or conductivity of the ionic polymer. By creating a separate grounded shielding electrode between the two parts, it is possible to suppress significantly the undesired cross-talk from the actuator to the sensor. The paper at hand compares three different methods for separating sensor and actuator parts: manual scraping, machine milling, and laser ablation. The basis of comparison of the methods is the electrical characteristics of the device after realizing the surface patterns and the convenience of manufacturing.
