cochlear implants

The first fully implantable cochlear implant is now being fitted in patients, removing the external speech processor and battery pack that conventional devices require. Everything, including sound capture and power, sits under the skin, which should make the devices more discreet, durable and convenient for everyday life. Commenters on Hacker News greeted the news enthusiastically, discussing the engineering behind the device and what it could mean for people with hearing loss.
