Dielectric film and transducer including the same

Abstract

A dielectric film of the present invention includes an elastomer and barium titanate particles with a crystallinity of 80% or more. The elastomer and each of the barium titanate particles each have a functional group, the functional groups can react with each other, and through the reaction of the functional groups, a cross-linked structure with the elastomer and the barium titanate particles is formed. With this structure, the dielectric constant and volume resistivity of the dielectric film of the present invention are high. A transducer of the present invention includes the dielectric film and a plurality of electrodes with the dielectric film interposed therebetween. The transducer of the present invention is excellent in resistance to dielectric breakdown and can output a large force.
