The present invention relates to flexible thin film batteries on semiconducting surface or the conductive or insulating packaging surface of a semiconductor device and methods of constructing such batteries. Electrochemical devices may be glued to a semiconducting surface or the conductive or insulating packaging surface of a semiconductor device or deposited directly thereon. The invention also relates to flexible thin film batteries on flexible printed circuit board where the electrochemical devices may also be glued or deposited on the flexible printed circuit board.

Thin film battery on an integrated circuit or circuit board and method thereof

A system that powers a wireless sensor mechanism from ambient sources without the need to replace a battery is disclosed. The present invention uses an energy harvesting mechanism built onto, for example, a substrate to recharge a rechargeable energy storage mechanism that is built on the same substrate. The energy storage mechanism provides power to a transmission/receiving mechanism and microprocessor that may also be arranged on said substrate. The energy-harvesting mechanism may be combined with a power management unit to enable efficient use and regulation of the harvested energy.

Environmentally-powered wireless sensor module

Described herein is, for example, a battery or capacitor over voltage (overcharge) and under-voltage protection circuit, that, for example, is adapted to not draw current from the battery or capacitor to be charged unless charge energy is detected and to not charge an energy storage device when an over-charge condition is sensed. The protection circuit may, for example, not be turned on unless an over voltage condition is present. Incoming energy to the system can be shunted to ground via a shunt load of various types including resistive loads and active components such as a zener diode. In some embodiments, no switching of the inbound power is required. Within limits, no regulation of inbound power is needed. When inbound power is sufficient to charge the battery or capacitor, regulation can occur via the applied shunt regulator if overcharge voltage conditions exist. Either type of charge source, voltage or current, can be used to provide charge energy. Combining said battery or capacitor over voltage (overcharge) and under-voltage protection circuit with electronic loads, such as wireless sensors, may lead to autonomously-powered wireless sensor systems.
