Researchers at the University of California San Diego have designed a sensor in the form of a temporary tattoo that can monitor a person`s progress during exercises. It can also generate electricity from their perspiration.
Exploiting the electron`s tiny magnetic moment or `spin`, scientists have discovered a new method to efficiently generate and control currents based on the magnetic nature of electrons in semi-conducting materials - offering a radical way to develop a new generation of electronic devices.
Researchers including an Indian origin have built a low-cost gesture recognition system that runs without batteries and lets users control their electronic devices hidden from sight with simple hand movements.
Scientists have come up with a simple one-step process that produces both n-type and p-type doping of large-area grapheme surfaces could facilitate use of the promising material for future electronic devices.
