Short Description |
|||||||||||||||
Ching-Hsiang Cheng is a Research Engineer and also Assistant Professor in the Research Institute of Innovative Products & Technologies, The Hong Kong Polytechnic University, Hung Hom, Kowloon, Hong Kong. Ching-Hsiang Cheng was born in Taipei,Taiwan. He received the B.S. degree in Mechanical Engineering from National Taiwan University in 1993. After completeing the military service in 1995, he got admission from Cornell University, NY, U.S.A. and awarded with Master’s degrees in both Mechanical and Electrical Engineering from Cornell University in 1998. During his master's study, he has developed biomedical pressure sensors, variable capacitors, and optical accelerometer using MEMS technology. Following his master's degree, he joined Professor Khuri-Yakub’s Ultrasonics Group in Electrical Engineering at Stanford University, CA and received his Ph.D. degree in 2005. During his doctoral research, he has developed electrical through-wafer interconnects to integrate the 2D capacitive micromachined ultrasonic transducer (CMUT) arrays with electronics, which has only 0.05 pF of parasitic capacitance for each interconnect. He has also developed CMUT for different applications including medical ultrasonic imaging, underwater camera, SAW filter, and Non-Destructive Inspection (NDI). After receiving his doctoral degree, he was invited to join Professor Kenneth Goodson’s Microscale Heat Transfer Group in Mechanical Engineering also in Stanford University as a postdoctoral scholar. He has developed a microfluidic system with integrated sensors and heaters for microprocessor cooling and fuel cell applications. After completing his postdoctoral research, he joined Industrial Technology Research Institute (ITRI) in Taiwan as a researcher and became a project leader after three months. He has developed tactile and thermal sensor arrays for robotics applications and nanoimprint technology for forming of micro to nano scale miniature polymeric based devices. In 2006, he has been appointed as a Research Engineer and also Assistant Professor in the Research Institute of Innovative Products and Technologies (RIIPT) of The Hong Kong Polytechnic University. His research interests include microfluidic systems with integrated sensors and actuators, capacitive micromachined ultrasonic transducers (CMUT), electrical through-wafer interconnects, polymeric tactile sensor arrays, nanoimprint technology, and microelectromechanical systems (MEMS) for healthcare applications. |
