In what might be called path-breaking in the field of bio-engineering, the Department of Electrical Engineering and Computer Science at MIT is working to cultivate the use of glucose cells and several other innovations which can be used to propel biomedical devices like pacemaker and cochlear implants.
Associate Professor of Electrical Engineering at the Massachusetts Institute of Technology, Rahul Sarpeshkar was at the MIT Technology Review 2012 in Bangalore recently, where he had a discussion on the projects he and his team of PhD scholars have been working on for sometime and have now started yielding results.
This is happening with me Daily, My mother scolds me everyday for it. When I am working on my Laptop writing something or searching something or doing something related to www.biomedikal.in. I respond to her in ‘YES” or ” NO” n sometimes I get irritated as well , Then I get a Big lecture from her. This is what I got to know from a 
study and its damn interesting.
You’re sitting at the breakfast table, checking your email or reading last night’s sports scores, and your spouse asks you a question — and you don’t respond. Then comes the inevitable: “Are you listening to me?” And you nod your head but really haven’t heard a thing.
SoundBite hearing system is the world’s first and only non-surgical and removable hearing solution designed to imperceptibly transmit sound via the teeth to help people who are essentially deaf in one ear regain spatial hearing ability and rejoin the conversation of life.
It employs a well-established principle called bone conduction to deliver clear, high quality sound to the inner ear. Nearly invisible when worn, the SoundBite system consists of an easy to insert and remove ITM (in-the-mouth) hearing device – which is custom made to fit around either the upper left or right back teeth – and a small microphone unit worn behind the ear. No modifications to the teeth are required.
A hearing aid is an electro acoustic body-worn apparatus which typically fits in or behind the wearer’s ear, and is designed to amplify and modulate sounds for the wearer.
It makes some sounds louder so that a person with hearing loss can listen, communicate, and participate more fully in daily activities. A hearing aid can help people hear more in both quiet and noisy situations. However, only about one out of five people who would benefit from a hearing aid actually uses one.The hearing aid receives sound through a microphone, which converts the sound waves to electrical signals and sends them to an amplifier. The amplifier increases the power of the signals and then sends them to the ear through a speaker.
A hearing aid is a device used to help hard-of-hearing people hear sounds better. In the past, a funnel-like amplification cone, called an “ear trumpet” or “ear horn” was used. Also sometimes used was a desk with a built-in amplifier into which a microphone and earphones could be plugged; these worked better than passive ear trumpets but were not portable.
