Methods, systems, and techniques for the contactless operation of capacitive micromachined ultrasonic transducers (CMUTs) and CMUT arrays. Contactless operations refers to both the contactless transfer of energy and information between the transducer(s) and the controlling subsystem. A system includes a CMUT, a first alternating current voltage source, a first inductor electrically coupled to the first voltage source, and a second inductor electrically coupled to the CMUT. The second inductor is physically decoupled from, and positioned to be wirelessly coupled to, the first inductor. A contactless configuration is useful for a wide range of applications, from wearable transducers to high-end ultrasound imaging systems.
