Deep Brain Implants

Implant charging is a key need for deep brain implants.  In Engadget.  " ... Stanford researchers have figured out a way to wirelessly charge electronic devices that are deep inside your body. Currently pacemakers and nerve transmitters need to have large receiving coils near the top of your skin to charge up (limiting where you can put them), or periodically have their battery replaced through surgery.
