Abstract:
1. A therapeutic ultrasound device comprising: a substrate; at least one high power capacitive micromachined ultrasonic transducer having a structure including a membrane electrode and a counter electrode, the membrane electrode having a membrane thickness, the membrane electrode separated from the counter electrode by a gap height within the at least one high power capacitive micromachined ultrasonic transducer; and at least one imager transducer comprising a capacitive micromachined ultrasonic transducer having a structure including a membrane electrode and a counter electrode, the membrane electrode having a membrane thickness, the membrane electrode separated from the counter electrode by a gap height within the at least one imager transducer, the at least one high power capacitive micromachined ultrasonic transducer and the at least one imager transducer being monolithically integrated on the substrate such that the at least one high power capacitive micromachined ultrasonic transducer is disposed laterally with respect to the at least one imager transducer along a surface on the substrate, the at least one high power capacitive micromachined ultrasonic transducer separated from the at least one imager transducer, the structure of the at least one imager transducer differing from the structure of the at least one high power capacitive micromachined ultrasonic transducer in gap height or both membrane thickness and gap height.
