A Miniature Photoacoustic Sensing System with Advanced PMUT and VCSEL Devices
This study presents a high-fill-factor piezoelectric micromachined ultrasonic transducer (PMUT) array fabricated via the cavity silicon-on-insulator (CSOI) process. The center frequency of the PMUT is 4.89 MHz in air and 3.5 MHz in a gel-type couplant, along with a -6 dB photoacoustic (PA) bandwidth...
