Medical devices powered by the ear itself - MIT Media Relations
Tapping a biological "battery" current source in the ear to power microelectronics. Potential applications in implantable hearing aid amplifiers that are "self powered" and thus batteryless.

A Photo-Thermal-Electrical Converter Based On Carbon Nanotubes for Bioelectronic Applications - Miyako - 2011 - Angewandte Chemie International Edition - Wiley Online Library
Interesting biocompatible power transfer research for implantable electronics, since it uses lasers that can pass through living tissue. Only issue is inherent to the process; namely, you are using a medium to convert tissue penetrating laser light to heat, then using a conventional thermoelectric generator embedded in the medium to generate power internally, which means you have a non-trivial amount of waste heat to reject through body tissue and fluids. As an alternative to skin penetration for power transfer this is nice, and it is not sensitive to EMF interference like induction pads, but induction pads are more efficient probably and generate less heat internally. This might be a good application for sensors, but may not be ideal for larger devices like assist pumps or pacemakers.

Technology Review: Power from Glucose
A potentially interesting solution to power implants and other medical devices, such as pacemakers and insulin pumps. But the interesting long term goal is an auxiliary excess glucose/calorie consume in the body, to overtake the normal metabolism. Basically, the idea would be to implant the biofuelcell in obese people (or people with oddball metabolism or excess glucose in their bodies such as diabetics), run the biofuelcell to reduce blood glucose levels. In an obese person, the body would react like it's being overly exercised (or starved?) and burn fat to compensate. One of the long term problems with obesity is the difficulty to both increase caloric expenditure while reducing food intake. This would neatly bypass the expenditure problem by having a secondary calorie consumer, since realistically, nobody is reliably capable of reducing their food consumption. But I wonder about the caloric starvation effect on hunger...
