摘要：An energy harvesting system and method having improved efficiency. A primaryenergy harvesting device is used to generate a first electrical output signal. The first
electrical output signal is applied to a first switching circuit. A secondary energyharvesting device is used to generate a second electrical output signal that is used topower a second switching circuit. The second switching circuit generates the switchingdrive signal for the first switching circuit, which in turn generates a final output signal. Byusing a second energy harvesting circuit operating in connection with a different
structure, and a secondary switching circuit, less power from the signal generated by theprimary energy harvesting device is needed to power the first switching circuit. Thisresults in a greater percentage of the output power of the first signal being usable by anexternal device.
