Current Research Interests

YAO Kui's research areas cover smart materials and their applications as sensors, actuators and transducers. The materials studied include ferroic, piezoelectric, dielectric, photovoltaic, chemical and bio sensing materials. He is interested in understanding and improving the structure and properties of these smart materials, and further exploring their signal/energy conversion and storage functional mechanisms including their applications. As the program manager, he is leading a research program focusing on material-critical sensors and transducers at Institute of Materials Research and Engineering in A*STAR. Working together with his colleagues and students, he has designed and demonstrated a variety of material-critical sensors, actuators, and transducers on the basis of the functional mechanisms of the smart materials. Processing of functional thin films, thick films, multilayers, and micro/nano fabrication processes are applied to produce devices.

Biographical Information

YAO Kui received the bachelor degree in electronics engineering and the Ph.D in electronic materials and devices, both from Xi'an Jiaotong University, China, in 1989 and 1995, respectively, and the master degree in technical physics from Xidian University, China, in 1992. He joined Institute of Materials Research and Engineering (IMRE) in Singapore in 1997 as a research fellow. After several promotions, he is currently a principal scientist and a program manager in IMRE, A*STAR, and an adjunct professor in School of Material Science and Engineering (MSE), NTU. During 1998 - 1999, he worked in the Materials Research Laboratory (MRL), The Pennsylvania State University, USA. Previously, he was a postdoctoral fellow in Microelectronic Center, Nanyang Technological University (NTU), Singapore, during 1995-1997.
