Cochlear Implants Without Exterior Hardware!
(Ivanhoe Newswire) – A new low power signal-processing chip could lead to a cochlear implant that requires no external hardware.
Researchers at MIT’s Microsystems Technology Laboratory (MTL), along with physicians from Harvard Medical School and the Massachusetts Eye and Ear Infirmary (MEEI), developed the chip that would allow the implant to be wirelessly recharged in about two minutes using a cell phone and run for about eight hours on one charge.
Existing cochlear implants require a bulky one-inch diameter transmitter be affixed to the skull, with a wire attached to a microphone and power source. “The idea with this new design is that you could use a phone, with an adaptor, to charge the cochlear implant, so you don’t have to be plugged in,” Anantha Chandrakasan, the Joseph F. and Nancy P. Keithley Professor of Electrical Engineering and corresponding author, was quoted as saying. “Or you could imagine a smart pillow, so you charge overnight, and the next day, it just functions.”
