Students in the field of CMUT design, development and application

The Microacoustic Systems (MAS) Group in System Packaging (SP) department specializes in the development and fabrication of Capacitive Micromachined Ultrasound Transducers (CMUTs) building on SP’s well established wafer bonding technology. CMUTs are emerging as excellent alternatives to conventional ultrasound transducers because of their numerous advantages like miniaturization, wide bandwidth, design flexibility, high temperature stability, batch production and high sensitivity. Having demonstrated several use cases of CMUTs in the past, the MAS group is actively researching innovative CMUT designs for future applications.
