Patent abstract
A push-pull capacitive micromechanical ultrasound transducer (CMUT) is provided for ultrasound imaging or therapy. Gaps and electrodes on both sides of an electrostatic membrane provide push-pull operation. The membrane is oriented to flex in a direction of acoustic propagation. A surface connected to the membrane may better expose the movement to the acoustic medium even in the push-pull arrangement.
