BPN628: High Frequency Piezoelectric Micromachined Ultrasound Transducers (PMUTs)

Project ID BPN628
Website
Start Date Mon 2011-Aug-15 10:31:47
Last Updated Thu 2014-Jan-30 21:33:24
Abstract The goal of the current research is to design and fabricate high frequency piezoelectric micromachined ultrasound transducers (PMUTs) for medical imaging and fingerprint sensors, which requires a narrow acoustic beam and high transmitting and receiving sensitivities. The simple process is developed to enable PMUT array with a high fill factor and small size of devices. The fabricated PZT and AlN PMUTs are characterized in mechanical, electrical and acoustic domains. Further characterizations of acoustic beam size and pulse echo imaging are to be done for final demonstration.
