BIOGRAPHY
Hao-Yen Tang was born in New Taipei City, Taiwan(ROC) in 1989. He received the B.S. degree with top 3% ranking in electrical engineering from National Taiwan University, Taipei, Taiwan, in 2011. After that he served national compulsory military service for one year.
Currently, he is a Graduate Student Researcher in Berkeley Sensor and Actuator Center at University of California, Berkeley, where he is pursuing his Ph. D. in electrical engineering. His research interests include energy harvesting system, sensor interface circuits, and mixed signal integrated circuits.

Ultrasonic Fingerprint Sensor Using Piezoelectric Micromachined Ultrasonic Transducers (PMUTs) [BPN722]
The proliferation of electronic devices such as smartphones creates a pressing need for reliable biometric authentication. Present solutions such as capacitive fingerprint sensors have failed to gain wide acceptance due to there susceptibility to contamination from oils, perspiration, and dirt. Ultrasonic fingerprint sensors solve these problems but currently available devices too large and costly for deployment in consumer devices. The goal of this project is to fabricate a fingerprint sensor based on a piezoelectric micro-machined ultrasonic transducer (PMUT) array and integrated electronics. A test chip comprising an 8 by 24 array of PMUTs fabricated on a 125um pitch and per-transducer readout electronics is presently in fabrication.
