Abstract:
A power generation device includes: a composite layer formed by a dielectric elastomer with ferroelectric particles dispersed therein; and a pair of electrodes disposed on opposite sides of the composite layer, the pair of electrodes being stretchable and compressible along with stretch and compression of the composite layer. The ferroelectric particles have crystal orientability and are orientationally dispersed in the dielectric elastomer, and are polarized in the layer thickness direction of the composite layer.
Abstract:
A polymer composite piezoelectric body is obtained by conducting polarization treatment on a composite having piezoelectric particles uniformly mixed by dispersion in a polymer matrix containing cyanoethylated polyvinyl alcohol.
Abstract:
A perovskite oxide film is formed on a substrate, in which the perovskite oxide film has an average film thickness of not less than 5 μm and includes a perovskite oxide represented by a general formula (P) given below: (K1−w−x, Aw, Bx)(Nb1−y−z, Cy, Dz)O3 - - - (P), where: 0
Abstract:
A ferroelectric oxide structure includes a substrate and a ferroelectric thin-film deposited on the substrate. The ferroelectric thin-film has a thickness of greater than or equal to 200 nm and a tetragonal crystal system. The ferroelectric thin-film has (100) single-orientation crystal orientation.
