PIEZOELECTRIC ACTUATOR WITH PASSIVE GAP FOR PUSH-PULL MOTION |
摘要 |
<p>The invention relates to a Stick-Slip piezoelectric actuator comprising a piezoelectric element with active zones and passive zones, said active zones being transversally deformable by applying different voltages, said passive zones not being actively deformable, characterized by the fact that said piezoelectric element is designed to have at least one zone working in contraction against at least one zone working in expansion, in such a way that both of said working zones may perform a push-pull motion.</p> |
