Abstract

Official abstract text for this publication.

A transducer that converts electrical energy to mechanical energy, the transducer includes: a dielectric layer; a first electrode that is provided on one surface of the dielectric layer; and a second electrode that is provided on another surface of the dielectric layer. At least one of the first electrode and the second electrode becomes an insulator, before the dielectric layer suffers insulation breakdown by voltage that is applied between the first electrode and the second electrode.

First claim

1 . A transducer that converts electrical energy to mechanical energy, the transducer comprising: a dielectric layer; a first electrode that is provided on one surface of the dielectric layer; and a second electrode that is provided on another surface of the dielectric layer, wherein at least one of the first electrode and the second electrode becomes an insulator, before the dielectric layer suffers insulation breakdown by voltage that is applied between the first electrode and the second electrode. 2 . The transducer according to claim 1 , wherein at least one of the first electrode and the second electrode includes porous carbon particles. 3 . The transducer according to claim 2 , wherein the porous carbon particles include pores each having a pore diameter of 2 nm or more and 100 nm or less on surfaces. 4 . The transducer according to claim 3 , wherein the porous carbon particles further include pores each having a pore diameter of 0.5 nm or more and less than 2 nm on the surfaces. 5 . The transducer according to claim 2 , wherein the porous carbon particles include pores each having a pore diameter of 0.5 nm or more and less than 2 nm and pores each having a pore diameter of 4 nm or more and 20 nm or less on surfaces. 6 . The transducer according to claim 2 , wherein an average particle diameter of the porous carbon particles is 1 μm or more and 20 μm or less. 7 . The transducer according to claim 2 , wherein an aspect ratio of the porous carbon particles is 10 or less. 8 . The transducer according to claim 2 , wherein the porous carbon particles are made from a raw material that is a plant derived material in which a content of silicon is 5 mass % or more. 9 . The transducer according to claim 2 , wherein the porous carbon particles are biocarbon. 10 . The transducer according to claim 2 , wherein the first electrode and the second electrode further include a binder. 11 . The transducer according to claim 1 , further comprising: a first bonding layer that is provided between the first electrode and the dielectric layer; and a second bonding layer that is provided between the second electrode and the dielectric layer. 12 . An electronic device comprising: a transducer that converts electrical energy to mechanical energy, wherein the transducer includes a dielectric layer, a first electrode that is provided on one surface of the dielectric layer, and a second electrode that is provided on another surface of the dielectric layer, and at least one of the first electrode and the second electrode becomes an insulator, before the dielectric layer suffers insulation breakdown by voltage that is applied between the first electrode and the second electrode.
