Abstract
A device capable of measuring the capacitance of a dielectric elastomer by variably manipulating the voltage applied to the dielectric elastomer includes a capacitance estimating unit that acquires current detection values at a plurality of sampling times in a current reduction period in which, when an output voltage of a power source changes, an energizing current of a dielectric elastomer increases and then gradually decreases according to the change in the output voltage, and estimates the capacitance of the dielectric elastomer on the basis of a model representing a correlation between the time-dependent change of the energizing current and the capacitance of the dielectric elastomer in the current reduction period, and the current detection values.
