Podcast: Virtually Invisible Cochlear Implants

 On this week's Physics Central Podcast I've got an amazing story of how physics could improve quality of life for thousands of people. Researchers at Harvard Medical School and the Massachusetts Eye and Ear Infirmary are working on a new cochlear implant device which would eliminate the need for external hardware, and help the wearer better determine the direction of sounds. The new design is based around a new, low-power signal-processing chip developed by researchers at the MIT Microsystems Technology Laboratory. The chip is low power and wirelessly chargeable, removing the need for an external battery pack. It also combines with other technology to remove the need for an external microphone, and instead uses the wearer's natural ear. Listen to this week's podcast to learn more.
