Field tests are underway for a transdisciplinary research team at Boise State. Led by professor of electrical and computer engineering Dr. Sin Ming Loo, and geosciences professor Dr. HP Marshall, the team is working to develop a competitively-priced, self-contained system with the ability to pinpoint infrasound.

What on earth is infrasound? Much like the light spectrum which ranges beyond human perception (e.g. infrared), sound is also a spectrum. Infrasound refers to those sound waves with frequencies below the lower limit of human hearing.

This month, the team is testing their work at Black's Creek Public Shooting Range. Special thanks to Don Sturtevant and John Keane for their help at the Black's Creek facility.  Spending a sunny day at a shooting range sounds like fun, but these critical tests also provide students with important experience testing designs in real-world conditions.

The team's earlier work has been proven successful in detecting gunshots and snow avalanches. Current work is expected to be utilized in even more ways thanks to its portable design and quick set up.

ECE Seminar October 7: Printed Electronics for Air Force Applications

By Jenn Ambrose
 The Electrical and Computer Engineering Department at Boise State University invites you to attend a free public seminar hosted on Zoom. This week's seminar features  Dr. Emily Heckman, a Senior Research Engineer at Air Force Research Laboratory. October 7 @ 10:30 am  https://boisestate.zoom.us/j/92994002201 ABSTRACT |    This talk will provide an overview of the field of printed electronics and ongoing research efforts in this area at the Air Force Research Laboratory Sensors Directorate. Printed electronics is a subset of additive manufacturing that uses technologies such as inkjet and aerosol jet printing and various other direct-write tools to additively print electronic devices on flexible, conformal and traditional substrate platforms. The AFRL Sensors Directorate is currently exploring this technology for application areas such as RF circuits and antennas, optoelectronic devices, sensors, and rapid prototyping. Challenges such as post-processing, repeat...

Electrical Engineering Research Team Develops New Transistor

By Jenn Ambrose
The American Chemical Society (ACS) launched its new journal Applied Electronic Materials this year. One of Boise State’s own research teams landed a spot in the very first issue thanks to their novel work on a new type of transistor. “The new transistor opens up an exciting avenue of research,” says Dr. Kris Campbell, an associate professor in the Electrical and Computer Engineering Department. The featured work describes an optically-gated transistor developed in the Non-Volatile Memory research lab at Boise State University. Campbell’s research team includes undergraduate electrical engineering students Randall Bassine and Jeremy Astle and electrical and computer engineering doctoral student Faisal Kabir. Their unique work has led to a patent for Boise State University and has already been licensed by a company hoping to use the technology in their products. In this work, Dr. Campbell and her team demonstrate that a device comprised of alternating layers of sputtered amorphous c...
