Abstract
The demand for lightweight designs of electronics has grown in recent years. Therefore, to meet the demand, novel methods in material and product development are essential. An easy way of achieving lightweight energy storage is utilizing electroactive polymers such as ionic polymer metal composite (IPMC) materials. This work investigates the effect of cracks caused by tensile loading on the electrical/electrochemical performance of IPMC-based capacitors. The IPMC capacitor maintains its capacitance during minor cracking in the Pt electrodes from high tensile mechanical loads, then decreases. The reduction in capacitance measured with increasing strain displays a high correlation with the number of cracks.
