Controlling light is an important technological challenge—not just at the large scale of optics in microscopes and telescopes ...

Abstract: Magnetic tactile sensors are widely used in tactile servo and robotic manipulations because of their compact size and high sensitivity. However, their spatial resolution is constrained by ...

Crowbar circuits have long been the go-to safeguard against overvoltage conditions, prized for their simplicity and ...

Abstract: Reversely switched dynistor (RSD) is a solid-state semiconductor switch with very high critical switched current rising rate and peak forward current. As a two-terminal switch, the RSD is ...

RIKEN physicists have discovered for the first time why the magnitude of the electron flow depends on direction in a special kind of magnet. This finding could help to realize future low-energy ...
