A small energy harvesting device that can transform subtle mechanical vibrations into electrical energy could be used to power wireless sensors and actuators for use in anything from temperature and occupancy monitoring in smart environments, to biosensing within the human body.
TROY, N.Y. — The harsh conditions that equipment, satellites, and spacecraft are subject to in space pose significant challenges. Electronic systems must be protected from extreme heat and cold, while storage containers holding liquid propellants must be shielded from solar radiation.
A COVID-19 transmission model inspired by gas-phase chemistry is helping the Centers for Disease Control and Prevention (CDC) forecast COVID-19 deaths across the country. Developed by Yunfeng Shi, an associate professor of materials science and engineering at Rensselaer Polytechnic Institute, and Jeff Ban, a professor of civil engineering at the University of Washington, the model uses fatality data collected by Johns Hopkins University and mobility data collected by Google to predict disease spread based on how much a population is moving within its community.
Bioimaging technologies are the eyes that allow doctors to see inside the body in order to diagnose, treat, and monitor disease.
Heart disease is the leading cause of death worldwide for men and women. The most common type of heart disease, coronary artery disease, is caused when plaque builds up along the walls of arteries that carry blood to the heart. It is often diagnosed through a cardiac computed tomography (CT) scan, which shows doctors if arteries are narrowing.
