Harvester could capture energy from ambient rf signals

imec and the Holst Centre, along with the Delft University of Technology and the Eindhoven University of Technology, have designed and fabricated a self calibrating rf energy harvester which may pave the way towards capturing energy from ambient WiFi or GSM signals.

Miniature optical sensor boosts microphone performance

An optical sensor less than 1mm in diameter is set to improve the sensitivity of microphones, according to Norwegian research organisation SINTEF. The researchers have exploited optical diffraction and interference to allow the sensor to measure membrane movements of less than the diameter of an atom.

ST, Rambus sign cross licenses, settle lawsuits
