Your cochlear is a battery that could power your hearing aid

Research out from America reported in the Daily Mail shows that hearing aids could be powered by the bodies own power source, rather than hearing aid batteries.


Researchers at the Massachusetts Institute of Technology (MIT) have been working on a way to harness the energy that is generated by the cochlear in the process of natural hearing. They have proved in animal tests that tiny electrodes, inserted into the cochlear, can generate enough current to keep a miniature circuit board running and think that future developments could lead to tiny hearing aids or implants being powered by the body itself  possibly requiring no external parts.


Tests have been carried out on gerbils in the lab and proved successful but it remains to be seen if this technique would work with all types of hearing loss or along side cochlear implants. Check out the article here.
