Tze Wei Yeow

John Yeow is a Professor in the Department of Systems Design Engineering and is cross-appointed to Mechanical and Mechatronics Engineering and Electrical and Computer Engineering at the University of Waterloo. He is also the Director of the Advanced Micro & Nanodevice Lab at the university and holds the Canada Research Chair in Micro and Nanodevices.

Professor Yeow’s research expertise lies in Micro-/Nano- Electro Mechanical systems. He aims to develop mechanical machines that are integrated with microelectronics at the micron scale. New device concepts include, but are not limited to: the integration of micro-optics components, miniature signal processing devices, biomedical/genome processing devices, miniature electromechanical wireless components (filters, mixers, antennas), miniature opto-electromechanical devices (optical cross connect, optical relays, optical multiplexers, deformable optics), miniature biosensors and environmental sensors, and microfluidics devices. Professor Yeow also explores issues such as self-testing, self-assembly, and automated packaging.

He is currently developing nanodevices and highly selective sensors that will help create new medical instruments for diagnosing and treating disease. These include MEMS optical scanner for endoscopic optical coherence tomographic imaging, micromirror devices for genetic microarray reading and tissue imaging, robotics for micromanipulations of MEMS components, carbon nanotube-based sensors for biomedical applications, and lab-on-a-chip designs.

Additionally, Professor Yeow’s company ARTsensing Inc. has commercialized an invention which is a product of his research – the world’s first transparent and flexible radiation detector that measures ionizing radiation delivered to cancer patients during treatment.

In addition to his many accomplishments, Professor Yeow was the recipient of the Young Engineer Award from the Ontario Society of Professional Engineers in 2008.
