Researchers at MIT's Microsystems Technology Laboratory and physicians from Harvard Medical School and the Massachusetts Eye and Ear Infirmary designed hardware that will make cochlear implants fully implantable.
They made a processing chip small enough to run on an implanted battery. The system has two custom designed chips: one for signal processing with an implantable acoustic center, and another for wireless resonance charging.

The implant may be charged through a cellphone or by a charger implanted in a pillowcase. Researchers say the device can charge in two minutes and last up to eight hours. To date, it has only been tested on cadavers.
