Abstract
One or more thin film battery cells are embedded in a multilayer thin film flexible circuit board supporting electronic devices, such as power regulators, for forming an integrated battery and circuit module. The module can be made using conventional thin film processes. The module is well suited for applications where size and space limitations, such as on spacecraft or credit cards, require the use of ultra thin power sources integrated with respective electronic devices and printed circuits.
