I’m sure that this is years away from being used in people but the idea is pretty neat. Nano sized electrical cells that could power things in a person like an artificial retina, replacement cochlea, maybe even pacemakers. Maybe this could also serve as a way to correct vision like LASIK or radial keratotomy by flexing a liquid lens implanted in the eye. Something like that could be a new lease on vision for cataract sufferers.
