The innovative energy saving chip which will be presented in the next few days, can help people with cochlear implants to get rid of nosimy parts on an ear. The new technology will facilitate use of the medical devices intended for compensation of losses of hearing.
Existing cochlear implants use the small storage batteries similar to what are used in a watch. Such batteries are subject to a recharge or replacement. The new chip eats from the battery which is charged by air within two minutes and about eight hours without additional charge work, transfers the news Gigaom resource.
The idea consists in using phone with the adapter for a charging of a cochlear implant. It excludes need of continuous connection to a network — the professor of electrical equipment Ananta Chandrakasan from Massachusetts Institute of Technology (MIT) tells.
This week research group into which scientists of Technological laboratory of microsystems (MIT Microsystems Technology Laboratory) enter, Harward medical school (Harvard Medical School) and Massachusetts clinic eye and the ENT SPECIALIST diseases (Massachusetts Eye and Ear Infirmary), will show a prototype of such charger.
The new chip allows not only to get rid of the traditional charger, but also to reduce number of nosimy electronics on the head at the expense of use of technology of bone sound transmission – vibrations are transferred through ear stones. The chip works together with the special sensor which finds and converts vibrations in electric signals. Thus, loss of hearing is compensated without use of any external microphone. It became possible thanks to the wireless chip with low power consumption.
Researchers plan to adapt a wireless charging for all types of implants. In the future such devices can do without the external power supply in general. In 2012 the team of scientific MIT and the Harward university created the implanted electronic device eating energy from the chamber of an internal ear, rich with ions.
