Grant: Strategic Projects - Group
University of Alberta
$118,500.00
CMUTs with improved electrical safety and minimal charge effects
FY 2011-12
Summary
We are developing a new type of biomedical ultrasound transducer technology based on state-of-the-art
microfabrication technology. These transducers are essentially miniature membranes fabricated on a silicon
wafer which can vibrate to produce ultrasound or may be used to detect ultrasound signals. Compared to
traditional piezoelectric materials, typically used in medical ultrasound systems, microfabricated ultrasound
trasnducers offer unique performance advantages, and promise miniaturization to the point of implementing an
ultrasound imaging system on a chip. Present barriers preventing commercialization could be device reliability
and safety for patients since high voltages are sometimes needed to drive their operation. Our research aims to
directly address these issues. Our current feasibility data demonstrates promising performance couple with an
electrically-safe design. We aim to expand our present research to further improve device reliability and
performance.
