BIOGRAPHY
Yipeng Lu received the B.Sc. degree in Materials Science and Engineering from Jilin University, Changchun, China in 2007 and the M.Sc. degree in Microelectronics and Solid State Electronics from Shanghai Jiao Tong University, Shanghai, China in 2010. He worked in HUAWEI until 2011 when he joined into UCD MEMSLab under the supervision of Prof. David A. Horsley. He is currently pursuing his Ph.D. from Mechanical Engineering at UC Davis.

Novel Ultrasonic Fingerprint Sensor Based on High-Frequency Piezoelectric Micromachined Ultrasonic Transducers (PMUTs) [BPN628]
The goal of this project is to design and fabricate a novel ultrasonic fingerprint sensor based on high-frequency Piezoelectric Micromachined Ultrasonic Transducers (PMUTs). Present fingerprint sensors in portable devices, such as capacitive fingerprint sensors, have failed to gain wide acceptance due to their susceptibility to contamination from oils, perspiration and dirt. Ultrasonic fingerprint sensors solve these problems, but devices currently available are too large and costly for deployment in consumer devices. The proposed ultrasonic fingerprint sensors based on PMUTs are easy to integrate with circuits. A test chip of a 72x9 PMUT array with 60 um pitch and electronics for driving and receiving were fabricated and characterized, and high resolution images of a steel phantom were obtained. The second generation of test chips with PMUTs and electronics on the same die is fabricated and under characterization.
