US Patent 7144654 - Microscopic Batteries for MEMS

This patent from Bipolar Technologies has priority going back all the way to 1998 (due mostly to USPTO delays) and claims the basic configuration of microscale batteries integrated with microelectromechanical systems. While advantagous to conventional MEMS devices such as accelerometers and optical switches, developments in microrobotics may also require such integration. Claim 1 reads:

1. In combination, at least one microfabricated microelectronic circuit the area of which is no greater than the area of a microelectromechanical system and a microfabricated microscopic battery the area of which is less than the area of the microfabricated microelectronic circuit integrated with the microfabricated microelectronic circuit as an internal low power loss source of electrical energy.
