Bipolar Piezoelectric Buckling Actuators

IEEE/ASME Transactions on Mechatronics, 2014
A nonlinear piezoelectric amplification mechanism utilizing structural buckling is presented, and its static and dynamic properties are measured and analyzed. Buckling is a pronounced nonlinear effect that occurs at a structurally singular point. A small piezoelectric displacement on the order of 10 μm results in a large buckling displacement on the ...
