Faster 'smart Sensor' is Developed

RALEIGH, N.C., April 22 (UPI) — U.S. scientists say they’ve created a “smart sensor” that can provide faster response times for military and security applications.

North Carolina State University Professor Jay Narayan said the new sensors, developed in a project funded by the National Science Foundation, are also designed to operate under extreme conditions, such as those in Afghanistan.

“We’ve taken a sensor material called vanadium oxide and integrated it with a silicon chip,” Narayan, co-author of the study, said. “Normally sensors are hardwired to a computer. But now the sensor is part of the computer chip itself. The advantage is that now you have a smart sensor that can sense, manipulate and respond to information.”

Researchers said the new technology was possible due to Narayan’s discovery of “domain matching epitaxy,” which allows the creation of single, defect-free crystal layers of different materials that amplify the transmission of electronic signals between the materials.

The research — co-authored by Professor Roger Narayan and doctoral students Tsung Han Yang, Ravi Aggarwal, A. Gupta and H. Zhou — was presented this month at a meeting of the Materials Research Society in San Francisco.

The study also was reported in the Journal of Applied Physics and the journal Applied Physics Letters.
