Title: Piezoelectric actuator and multilayer piezoelectric actuator
Inventor: KAWAKITA SHINICHIRO
IPC: H01L41/09
Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To increase the amount of deformation of a piezoelectric actuator that is composed of a two-plate piezoelectric unimorph or piezoelectric bimorph. SOLUTION: A piezoelectric actuator A is composed of a pair of two disk- shaped piezoelectric unimorphs U that are coaxially provided, while they oppose each other, three support members 1 that are jointed and fixed at three points of both peripheral edge part of the two piezoelectric unimorph U and support the points with a constant gap among them, and nine spacer members 5 that are pinched at both peripheral edge parts of two piezoelectric unimorphs U between the support members 1.  When a piezoelectric plate 3 shrinks and the piezoelectric unimorph U is deformed convexly toward the outside, a greater amount of displacement can be obtained at the center of a piezoelectric actuator A, since the support members 1 for preventing the peripheral edge of the elastic plate 2 from being deformed are provided only partially, and the spacer members 5 perform the support so that the peripheral edge of the elastic plate 2 between the support members 1 of the spacer members 5 do not retreat.
