This would be prohibitively large to implant in the brain.
Betavoltaics could provide a novel power source, I believe they are used in some pacemakers. RF would be a problem because cancer.
People forget that magnetic induction can also be used for data and power transfer simultaneously, I believe they use this approach with some cochlear implants.
- robryk 13y ago> RF would be a problem because cancer. Could you provide some evidence for this? Also, isn't magnetic induction basically RF?
- pocketstar 13y agoelectromagnetic radiation(photons) is VERY VERY VERY different from magnetic fields(fucking magnets how do they work?) the driving physics behind magnetic induction. Yes RF is non-ionizing, but research linking it to cancer is generally inconclusive. So I concede I was too bold saying RF causes cancer, but right now we just don't know. It would probably be possible to power it with RF power harvesting and multiplex the MEA with a MSP430. Now that would be a fun research project.
- robryk 13y agoIn order to transfer power using magnetic induction you need a _variable in time_ magnetic field, which causes a variable in time electric field to appear. That seems to me to be exactly the description of an electromagnetic wave.
