NASA's Wi-Fi reflection chip

Wi-Fi 'reflector' hooks you up at 0.1 per cent of current power budget

By using absorption and reflection to indicate data states, NASA reckons it's created a Wi-Fi device for the wearable market that uses just 0.1 per cent of the power of ordinary transceivers. Working with Frank Chang at Caltech UCLA, the JPL boffin Adrian Tang is keen on ways to let devices with relatively low communications …
