31 Claims

1. A microfabricated battery comprising a system for internal storage of electricity comprising reactants, the microfabricated battery having a volumetric size which is microscopic including a micrometer footprint substantially less than 20 cm2 and congruent with a microelectronic circuit accommodating integration with the circuit to provide long term stored power and to materially limit power losses, the microfabricated battery comprising a body of material having a first microfabricated electrode of chemically reactant material, a second microfabricated electrode spaced from the first electrode and a microscopic amount of internal ion-transmitting electrolyte which restricts electronic current flow and accommodates reactions at the electrodes contained within an internal microfabricated space in the body accessible to both electrodes.
