Inspired by the inner ear, MIT associate professor Rahul Sarpeshkar and student Soumyajit Mandal have developed a radio chip that requires very little power to function as a universal wireless device for electrical signals by mobile devices. The chip is called the radio frequency cochlea, named after the inner ear.
The radio chip is designed to perceive signals at a million fold higher than frequencies for wireless applications. The RF cochlea is inscribed on a silicon chip that is measured 1.5mm x 3mm and works as an analog spectrum analyzer that detects all of the electromagnetic signals in the area. The two have filed a patent for the device.
