Beschreibung
Zusammenfassung:	A device includes a plurality of energy harvesting circuits, an energy storage device, a first diode and a second diode. The plurality of energy harvesting circuits includes a first energy harvesting circuit and a second energy harvesting circuit. The first energy harvesting circuit includes a first transducer and the second energy harvesting circuit includes a second transducer. The first transducer is structured for converting a different kind of energy into electricity than is the second transducer. The first diode is electrically connected between the first energy harvesting circuit and the energy storage device and the second diode is electrically connected between the second energy harvesting circuit and the energy storage device. The first diode is oriented to prevent energy from the second energy harvesting circuit from being dissipated in the first energy harvesting circuit and the second diode is oriented to prevent energy from the first energy harvesting circuit from being dissipated in the second energy harvesting circuit.
