Abstract:
A piezoelectric/electrostrictive device comprising:a pair of mutually opposing thin plate sections made of metal and a fixation section for supporting said thin plate sections; an object attached to forward end portions of said pair of thin plate sections; and one or more unimorph piezoelectric/electrostrictive elements arranged on at least one thin plate section of said pair of thin plate sections, said at least one thin plate section defining a substrate for each respective unimorph piezoelectric/electrostrictive element, wherein each of said piezoelectric/electrostrictive elements includes a piezoelectric/electrostrictive operating portion defined between opposed electrodes, and the piezoelectric/electrostrictive operating portion extends from an outer surface of the fixation section onto at least a portion of the thin plate sections, wherein: an areal size of a surface of said object opposed to said thin plate section is larger than an areal size of an object attachment surface of said thin plate section.
