Investigation of PDMS as coating on CMUTs for imaging [PDF]
2014 IEEE International Ultrasonics Symposium, 2014 A protective layer is necessary for Capacitive Micromachined Ultrasonic Transducers (CMUTs) to be used for imaging purpose. The layer should both protect the device itself and the patient while maintaining the performance of the device. In this work Sylgard 170 PDMS is tested as coating material for CMUTs through comparison of transmit pressure and ...
