Diamond-based capacitive micromachined ultrasonic transducers in immersion

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2013
Diamond is a superior membrane material for capacitive micromachined ultrasonic transducers (CMUTs). By using ultrananocrystalline diamond (UNCD) membrane and plasma-activated wafer bonding technology, a single diamond-based circular CMUT is demonstrated and operated in immersion for the first time.
