Quantum tunneling pushes the limits of self-powered sensors

Shantanu Chakrabartty's laboratory has been working to create sensors that can run on the least amount of energy. His lab has been so successful at building smaller and more efficient sensors, that they've run into a roadblock ...

A touch of gold sends crystals electric with excitement

A touch of gold—or another noble metal—can change the structure of a crystal and its intrinsic properties, physicists at the University of Warwick have demonstrated in a display of modern-day alchemy.

Piezomagnetic material changes magnetic properties when stretched

Piezoelectric materials, which generate an electric current when compressed or stretched, are familiar and widely used: think of lighters that spark when you press a switch, but also microphones, sensors, motors and all kinds ...

Sound waves precisely position nanowires

(Phys.org) —The smaller components become, the more difficult it is to create patterns in an economical and reproducible way, according to an interdisciplinary team of Penn State researchers who, using sound waves, can ...

Researchers generate electricity from viruses

Imagine charging your phone as you walk, thanks to a paper-thin generator embedded in the sole of your shoe. This futuristic scenario is now a little closer to reality. Scientists from the U.S. Department of Energy's Lawrence ...
