Abstract:
1. A method for producing a piezoelectric/electrostrictive device comprising a pair of opposed thin plate sections having a movable section at one end thereof, a fixing section supporting said thin plate sections, and at least one piezoelectric/electrostrictive element formed on at least one of said thin plate sections, said method comprising the steps of: providing a first ceramic green sheet for a thin plate section; providing a second ceramic green sheet having a first window section, wherein a portion of said first window defines at least a portion of a slit in said piezoelectric/electrostrictive device; providing a third ceramic green sheet having a second window section, said second window section being smaller than said first window section; interposing said second ceramic green sheet between said first ceramic green sheet and said third ceramic green sheet to form a laminated green ceramic body such that said first ceramic green sheet defines a portion of an outer surface of said laminated green ceramic body; sintering said laminated green ceramic body to form a laminated sintered ceramic body; forming at least one piezoelectric/electrostrictive element on a portion of said outer surface of said laminated green ceramic body or on a portion of an outer surface of said laminated sintered ceramic body; cutting a first portion of said laminated sintered ceramic body to expose said slit; providing a filler material in said slit; and cutting a second portion of said laminated sintered ceramic body to allow for movement of said movable section.
