Latest Patents

One of Itoh's latest patents involves a piezoelectric/electrostrictive device and the method of manufacturing it. This invention features a pair of opposing thin plate sections, movable sections, and fixed sections that support the thin plate sections and movable sections on a ceramic substrate. The process begins with the formation of a wiring pattern and a gap or insulating layer of cermet for filling the gap, which are then sintered. Following this, piezoelectric/electrostrictive layers and cermet electrode layers, which include both piezoelectric/electrostrictive material and conductive material, are alternately stacked in a comb-like structure on the ceramic substrate. This innovative approach results in a piezoelectric/electrostrictive device that incorporates a multilayer structure.
