Abstract
A piezoelectric/electrostrictive device including a pair of mutually opposing thin plate sections and a fixation section for supporting the thin plate sections. A piezoelectric/electrostrictive element is arranged on each of the pair of thin plate sections. Movable sections, having mutually opposing end surfaces, are formed proximate the ends of the thin plate sections. A distance between the end surfaces is not less than a length of the movable sections.
Claims12
A piezoelectric/electrostrictive device comprising:
- a pair of mutually-opposing thin plate sections and a fixation section for supporting said thin plate sections;
- movable sections provided at first end portions of said pair of thin plate sections;
- and
- one or more piezoelectric/electrostrictive elements arranged on at least one thin plate section of said pair of thin plate sections, each of said piezoelectric/electrostrictive elements including at least one electrode containing two portions separated from one another by a slit.
