    Abstract: A dielectric elastomer transducer according to the present invention includes a dielectric elastomer layer, and a pair of electrode layers sandwiching the dielectric elastomer layer. The electrode layers contain a binder and carbon black. The carbon black has a particle size distribution as measured by dynamic light scattering in which not less than 95% falls in a range of 0.15 to 8.0 ?m. The carbon black has a particle size as measured by laser scattering ranging from 0.4 to 50 ?m. The particle size distribution of the carbon black as measured by dynamic light scattering has a first peak that falls in a first range of 0.15 to 1.0 ?m and a second peak that falls in a second range of 1.0 ?m to 8.0 ?m. This structure achieves both stretchability and electrical conductivity of the electrode layers.

    Abstract: A dielectric elastomer power generation system of the invention includes: a power generation unit including a dielectric elastomer power generation element having a dielectric elastomer layer flanked by two electrode layers; a step-down unit including capacitors; a power storage unit for input of an output power from the step-down unit; and a control unit that controls the connection between the step-down unit and the power generation unit or power storage unit. The step-down unit includes first diodes and second diodes, where the first diodes form a circuit that connects the capacitors in series when the power generation unit is connected to the step-down unit, and the second diodes form a circuit that connects the capacitors in parallel when the step-down unit is connected to the power storage unit.
