Abstract
Official abstract text for this publication.
A piezoelectric actuated device includes one or more areas of piezoelectric material coupled to a substrate. The piezoelectric material may be placed on regions of the substrate that exhibit the greatest curvature and stress when the device is vibrating according to a desired structural Eigenmode of vibration. The piezoelectric material may have a non-uniform density.
First claim
Opening claim text (preview).
What is claimed is: 1. A piezoelectric actuated device comprising: a frame; a platform that can take on different angular displacements relative to the frame; at least one flexure coupling the platform to the frame; and piezoelectric material mechanically coupled to at least a portion of the frame, wherein the piezoelectric material has a non-uniform area density, wherein the device exhibits a desired structural Eigenmode of vibration that results in stress on the frame, and…
