AZONano -- Forget 9-volts, AAs, AAAs or D batteries: The energy for tomorrow’s miniature electronic devices could come from tiny microbatteries about half the size of a human cell and built with viruses. MIT engineers have developed a way to at once create and install such microbatteries -- which could one day power a range of miniature devices, from labs-on-a-chip to implantable medical sensors -- by stamping them onto a variety of surfaces.
