Technology has largely improved the quality of life for patients needing implantable electronic devices, such as pacemakers or cochlear implants. Pacemakers allow for the heart to function properly and cochlear implants restore hearing to deaf patients. The downfall of these types of technologies is the way in which they are powered. Batteries are a common power source, and while they can be designed to have lifespans of several years, they do eventually need to be replaced. One could argue that this, to an extremely small degree, undermines the benefits of having the implantable device.
Researchers at MIT may have found a way to completely remove this inconvenience associated with having an implantable electronic device. What if we used the resources in our own body to power the electronic components we put into it after injury? More
