Energy-efficient chip could improve mobile device battery power

A new energy-efficient microchip may lead to mobile devices and sensors with a far-longer running battery power.

The proof of concept technology, built by Massachusetts Institute of Technology (MIT) and Dallas, Texas-based semiconductor vendor Texas Instruments, claims to be up to 10 times more energy-efficient than current hardware.

The key to the energy efficiency was making the circuits on the chip perform at a lower than usual voltage. The new chip works at just 0.3 volts, as opposed to the usual 1 volt requirement.

Future applications for the technology include portable and implantable medical devices, and portable communication and networking devices.
