Or by chewing.  Back in the old days there were watches that wound their
springs by movement of the wrist, perhaps using a concentric weight on a
spindle.  If someone knows or can estimate the amount of power needed to run
a minimal processor and interface, I can calculate the amount of energy
likely to be generated by such motion with a device small enough to be
reasonably implanted.
