Document Type and Number:
Japanese Patent JP2585018
Kind Code:
B2
Abstract:
A piezoelectric pressure-sensitive element comprising a dispersion of a dipolarly oriented ferroelectric ceramic powder in a cured product of a composition comprised of an epoxy resin having at least two epoxy groups in the molecules, a compound having defined numbers of amino groups, benzene rings, carbonyl groups and methylene groups, and a crosslinking agent. A methd for making such a piezoelectric pressure-sensitive element is also described, in which the resin composition comprising a ferroelectric ceramic powder is thermally cured and applied with an electric field at a high temperature to cause dipolar orientation of at least the ceramic powder.
