Extremely small batteries could operate for years at nanoampere discharge rates.
Integrated microbatteries have been proposed to satisfy an anticipated need for long-life, low-rate primary batteries, having volumes less than 1 mm3, to power electronic circuitry in implantable medical devices. In one contemplated application, such a battery would be incorporated into a tubular hearing-aid device to be installed against an eardrum. This device is based on existing tube structures that have already been approved by the FDA for use in human ears.
This work was done by Jay Whitacre and William West of Caltech for NASA’s Jet Propulsion Laboratory.
