Professor Victor M. Bright of the Paul M. Rady Department of Mechanical Engineering delivered his Distinguished Research Lecture “Microscale Sensors and Machines” on November 2, 2021. In this talk, Professor Bright gave an overview of the history of microscale sensors and micromachines, and the contributions of his research.

The Distinguished Research Lectureship is among the most esteemed honors bestowed by the faculty upon a faculty member at the University of Colorado Boulder. Each year, the Research & Innovation Office (RIO) requests nominations from faculty for the Distinguished Research Lectureship, and a faculty review panel recommends recipients.

Big Sound from Nanoengineered Speakers

Big Sound from Nanoengineered Speakers Anonymous (not verified) Thu, 10/27/2016 - 13:02

At a concert, bigger is better when it comes to amplifiers and speakers, but research in CU Boulder mechanical engineering professor Victor Bright's Multidisciplinary Engineering Micro-Systems Group is demonstrating that small speakers can produce big sound too. How small? Fewer than 300 atoms thick.

Listen to a clip of music from the speakers

It's all thanks to the thermoacoustic effect, the ability to transform temperature fluctuations into sound energy. Recorded sound didn't begin until Thomas Edison's phonograph, but the thermoacoustic effect is a scientific principle that has been known for centuries and was studied for use in loudspeakers 100 years ago. Progress in nanofabrication has renewed interest in the phenomenon.

Bright's research group is now showing readily audible thermoacoustic effects from atomic-layer-deposited tungsten bridge structures less than 300 atoms thick.

The studies of the nanospeakers were led by research scientist Joseph J. Brown, PhD, and performed by undergraduate student Nathan C. Moore with graduate students Omkar D. Supekar and Jonas C. Gertsch. The research is providing new insights into acoustic measurements of thermoacoustic nanosystems.

The devices they create consist of suspended tungsten bridges around 25 nm thick and 17 μm x 2 μm in area that produce audible sound and music. Operated in parallel in large arrays, the devices produce sound pressure levels of 90-100 dB at frequencies above 10 kHz and ~10 W electrical input power, and the team was able to measure 104 dB output at 20 kHz.

The profile at Nanotechweb is based on the team's recently published paper in the journal Nanotechnology titled Ultrathin thermoacoustic nanobridge loudspeakers from ALD on polyimide.
