University of Arkansas physicists have successfully generated an electrical current from the atomic motion of graphene, discovering a new source of clean, limitless power. Paul Thibado, professor of physics and lead researcher in the discovery said, “An energy-harvesting circuit based on graphene could be incorporated into a chip to provide clean, limitless, low-voltage power for […]

In the lab of Fabrizio Carbone at Ecole Polytechnique Fédérale de Lausanne (EPFL) and their international colleagues, these physicists have now demonstrated experimentally the ability to coherently manipulate the wave function of a free electron down to the attosecond timescale. Attoseconds are 10 to the 18th of a second. The team also developed a theory […]

Researchers at Temple University and the University of Maryland has discovered a new class of magnets that expand their volume when placed in a magnetic field and generate negligible amounts of wasteful heat during energy harvesting. The researchers, Harsh Deep Chopra, professor and chair of mechanical engineering at Temple, and Manfred Wuttig, professor of materials […]

University of Michigan electrical engineers have built a piezoelectric generator that can harness energy from vibrations and convert it to electricity with five to 10 times greater efficiency and power than other devices in its class. It’s smaller than a penny. The UM team has built a complete system that integrates a high-quality energy-harvesting piezoelectric […]
