Sorry, but it won't be that easy. Living tissue can be severely damaged by even very modest amounts of excess heat. Implanted devices are limited to radiating <2 mW per square cm of surface area, and I expect nanotech devices would face the same constraint.
If you want to implement anything that consumes significantly more energy than normal tissue, you'll have to build a cooling system to carry off the excess heat. That's going to be a difficult task, since we can't use a traditional thermal heat-exchange system. My best idea at the moment would be to look for a fancy chemcal solution, but that could take a lot of searching. We'd need a strongly endothermic reaction that takes place easily in the environment of living tissue, and is easily reversed in an environment exposed to open air.
