Title:
圧電素子シートおよびその製造方法
Document Type and Number:
Japanese Patent JP6869260
Kind Code:
B2
Abstract:
Provided are: a piezoelectric element sheet, which exhibits a high piezoelectric constant, holds charged charge carriers for a long time, and maintains a high piezoelectric modulus; and a method for manufacturing the piezoelectric element sheet. The piezoelectric element sheet comprises a matrix resin dispersion of an insulating woven/nonwoven fabric, and is characterized in that charge carriers are retained. The method for manufacturing the piezoelectric element sheet is characterized in that: an insulating woven/nonwoven fabric is immersed in a solution in which a matrix resin is dissolved or dispersed; the woven/nonwoven fabric is impregnated with the matrix resin; and then charge carriers are injected, by a charging treatment, into the obtained sheet which is composed of a woven/nonwoven fabric-matrix resin dispersion.
