Medical devices, radio powered by the ear itself – MIT
Here is an interesting view to the future from a joint team from MIT, Harvard and the Mass. Eye & Ear Infirmary: a micro radio, implanted into the inner ear and powered by a natural battery that all mammals have in the ear.
Many interesting challenges addressed in the process, including
- Ultra low power, miniature radio
- Very low voltage source with energy harvester accumulating charge over 40seconds.
- Kick-starting the power management controller with an external RF field (once started, it runs from it’s own output)
Energy harvesting from in-vivo bio-chemical sources. Congratulations to the team.
