ABSTRACT:
A capacitive transducer having a significantly increased actuation force and improved response time as compared to similar prior art capacitive transducers. In the capacitive transducer of the present invention it is not necessary to balance response time and actuation force or to provide pre-strain to the transducer in a direction of actuation. Additionally, buckling in the capacitive transducer is prevented, or at least substantially reduced, in a simple manner.
