Derek Tsan is a M.A.Sc. student. He received his B.A.Sc. from the University of British Columbia in 2009, specializing in Nanotechnology and Microsystems. His current research focuses on developing highly sensitive dynamic strain sensors based on piezoelectric zinc oxide nanowires. These sensors are being developed as low-cost alternatives to traditional piezoceramic sensors for structural health monitoring applications.
Derek is the manager of the rheometer and 3D printer in LMRS 156, and has extensive experience with Matlab and GPIB instrument programming, 3D modelling and fabrication, drop-on-demand inkjet printing, and machine tools.

Abstract: Thin films composed of self-supporting ZnO nanowire arrays are fabricated via a hydrothermal approach without the presence of any substrates. The films can be transferred and bonded to an arbitrary substrate for device applications. As a demonstration, a piezoelectric converter is made which is able to generate electric charge under compressive forces.
