High-strain ionomeric–ionic liquid electroactive actuators
Published 2006“…Results demonstrate that the surface-to-volume ratio of the metal particulate is critical to increasing the capacitance of the transducer. Increased conductivity of the metal particulates produces improved response at higher frequencies (>10 Hz), but this effect is small compared to the increase in strain produced by maximizing the capacitance. …”
