MAE/HKCRC join seminar - Piezoelectric and Piezoelectret Devices Toward Smart Construction
Leveraging from the core MEMS (Microelectromechanical Systems) technologies, my group has been working on micro/nano piezoelectric and piezoelectret sensors and actuators toward practical applications such as smart construction. In the area of piezoelectric devices, I will discuss topics such as piezoelectric micromachined ultrasonic transducers (pMUTs) with various applications, PVDF nanofibers as nanogenerators as energy harvesters, and soft crawling robots. In the area of piezoelectret devices, I will talk about piezoelectret-based energy harvesters, strain/pressure sensors as wearable sensing systems for human health assessments, and sensors for robots.
Professor Liwei Lin is the James Marshall Wells Professor at the Mechanical Engineering Department and Co-Director at Berkeley Sensor and Actuator Center (BSAC) at UC Berkeley, and Interim Co-Director of Tsinghua-Berkeley Shenzhen Institute. His research interests are in design, modeling and fabrication of micro/nano structures; sensors and actuators; as well as mechanical issues in micro/nano systems including heat transfer, solid/fluid mechanics and dynamics. Dr. Lin is the recipient of the 1998 NSF CAREER Award for research in MEMS Packaging and the 1999 ASME Journal of Heat Transfer best paper award for his work on micro scale bubble formation. He led the effort to establish the MEMS division in ASME and served as the founding Chairman of the Executive Committee from 2004~2005. He is an ASME Fellow and has 23 issued US patents in the area of MEMS. He was the general co-chair of the 24th IEEE international conference on Micro Electro Mechanical Systems at Cancun, Mexico. He serves as a subject editor for the IEEE Journal of Microelectromechanical Systems, and Microsystems & Nanoengineering published by the Nature group.
