Presentation Title: Intelligent Sensor/Actuator for Human-Machine Interfaces

Abstract: Leveraging from the core MEMS (Microelectromechanical Systems) technologies, my group has been working on micro/nano sensors and actuators toward practical applications for human-machine interfaces. In this talk, I will present 6 main research results. In the area of personalized health by wearable systems, a piezoelectric pulse detector is developed to sense human pulse for health monitoring following the concept of traditional Chinese Medicine practices. In the second area, I will discuss our efforts in using graphene to make a transistor for gas detection in cell phone applications. The third topic is the development of flexible mechanical actuators as haptic feedback functions in applications such as AR/VR and robotics. Forth, I will discuss the development of piezoelectric micromachined ultrasonic transducers (pMUTs) with various applications, such as temperature, flow, blood pressure … In the fifth area, my group has been working on microfluidic devices and some of the biomedical applications will be introduced. The sixth topic is energy generation and storage systems, such as energy harvesters, supercapacitors, and batteries. Finally, I will also introduce some fun projects, such as an ultra-robust and fast moving piezoelectric robot similar to those of cockroaches.

Biography: Professor Liwei Lin is the James Marshall Wells Distinguished Professor at the Mechanical Engineering Department and Co-Director at Berkeley Sensor and Actuator Center (BSAC) at UC Berkeley. 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 MEMS. He was the general co-chair of the 24th IEEE international conference on Micro Electro Mechanical Systems at Cancun, Mexico. He serves as associate editor for Microsystems & Nanoengineering published by the Nature group.
