Indian scientists bridge audio divide

[Duer 157099]

More immediately, the RF Cochlea will vastly improve radio frequency spectrum in the newly dawning technology of cognitive and smart radios - vital devices that automatically make better use of unused frequencies in our increasingly bandwidth-crowded world.

Sarpeshkar and Mondal used the same design principles in the human ear to create the RF Cochlea. The device captures radio frequencies a million times higher than the 100 Hz (100 wave cycles per second) to 100,000 Hz that the human ear captures. It includes radio signals for most commercial wireless applications.

In Sarpeshkar's RF Cochlea, human-made inductors imitate the work of fluid mass in the ear, capacitors replicate ear membranes and active radio frequency amplifiers do the work of the outer hair cells in the ear that carry audio as electrical signals to the brain.
