Abstract: 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.

Abstract: A conductivity type of a protein semiconductor is controlled by controlling total amount of charge in amino acid residues, a p-type protein semiconductor or an n-type protein semiconductor is manufactured, and a pn junction is manufactured using the p-type protein semiconductor and the n-type protein semiconductor. The total amount of charge in amino acid residues is controlled by substituting one or more of an acidic amino acid residue, a basic amino acid residue, and a neutral amino acid residue, which are contained in protein, with an amino acid residue having different properties, chemically modifying one or more of an acidic amino acid residue, a basic amino acid residue, and a neutral amino acid residue, which are contained in the protein, or controlling polarity of a medium surrounding the protein.
