摘要： A transducer 1 includes a high-resistance layer 10 that includes an elastomer and has a volume resistivity of 10 12 Ω·cm or more, a pair of electrodes 30a, 30b that are arranged on both a front side and a back side of the high-resistance layer 10 and include a binder and a conductive material, and a medium-resistance layer 20 that is interposed between the electrode 30a and the high-resistance layer 10 on at least one of the front side and the back side of the high-resistance layer10, includes an elastomer, and has a volume resistivity that is smaller than the volume resistivity of the high-resistance layer 10 by two or more digits. In the transducer 1, the medium-resistance layer 20 is interposed between at least one electrode 30a and the high-resistance layer 10 to take advantage of the resistance to dielectric breakdown originally possessed by the high-resistance layer 10, thereby obtaining a larger force by applying a higher voltage.

摘要： 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.

摘要： A dielectric film includes an elastomer, and metallic oxide particles having a particle diameter of 100 nm or less that are chemically bonded to the elastomer and are dispersed in the elastomer in a state of primary particles. A method for manufacturing the dielectric film includes: a chelating process of adding a chelating agent to an organometallic compound to produce a chelate compound of the organometallic compound; a sol manufacturing process of adding an organic solvent and water to the chelate compound to obtain a sol of metallic oxide particles produced by the hydrolytic reaction of the organometallic compound; a mixed solution preparing process of mixing the sol of the metallic oxide particles and a polymer solution containing a rubber polymer having functional groups that optionally react with hydroxy groups to prepare a mixed solution; and a film forming process of applying the mixed solution onto a substrate, and curing the resultant coating film to obtain a dielectric film.
