Abstract

This paper discusses a simple characterization method for thin stacked dielectric elastomer actuators (DEAs), which is difficult to measure the mechanical impedance. We employ a method of suspension for characterizing the mechanical impedance. A weight is attached to a thin stacked DEA and then the DEA is electrically excited. The frequency response is obtained by measuring the vibration displacement. Consequently, we can estimate the mechanical impedance or viscoelasticity of the thin stacked DEA. From the experimental frequency response of electrical excitation, Young’s modulus and damping ratio were successfully estimated.
