The patent describes a conductive coating and bonding material for single element electrostrictive transducers and for those formed as a mosaic stack, or non-linear seriatim assembly of electrostrictive segments. The composition is a mixture of silver flakes and copper flakes in a matrix of any one of various commercially marketed room temperature curing epoxy resins. In addition to the silver flakes and copper flakes the composition also includes nickel powder which serves as an agent for stirring the mixture. The term electrostrictive is used in the generic sense to encompass ceramic materials and piezoelectric natural or grown crystals.
