ASSIST is working with two categories of sensors: non-invasive health sensors for bio-electric, biochemical, and acoustic monitoring; and environmental sensors that measure gasses, particulate matter, and temperature. The goals are to gather more accurate data on how the environment causes changes in physiological signals and to develop a multi-modal harvesters.

Tom Snyder, the lab’s industry liaison, demonstrated an asthma monitor at CES this year, which was both activated and powered by breath. “If we understand exposure to the ozone and monitor EKG and understand motion of the body…an asthma attack could be predicted as much as 24 hours before it happens,” he said, noting that this principle is currently being studied.

OAKLAND, Calif. – Researchers at North Carolina State University are using nanotechnology to create energy harvesting and storage devices for ultra-low power sensors. The federally-funded research aims to create battery-free, body-powered wearable health monitors.
