ELECTRO-ACTIVE ACTUATOR USING ELECTRO-ACTIVE POLYMER AND SHAPE MEMORY ALLOY

摘要

PURPOSE: An electro-active actuator is provided to secure a larger linear displacement than a ceramic piezoelectric method by employing electro-active polymer and shape memory alloy.;CONSTITUTION: An electro-active actuator comprises an electro-active deformation part(10) which is bent by application of power, first and second rotary shaft parts(31,32) which are coupled along the edges of the electro-active deformation part and rotate to face each other when getting close to each other by bending, and a rotation supporting part which supports the first and second rotary shaft parts. The rotation supporting part includes a guide unit which guides the first and/or second rotary shaft to move linearly.;COPYRIGHT KIPO 2012
