Abstract
An energy harvesting system includes a plurality of transducers. The transducers are configured to generate direct current (DC) voltages from a plurality of ambient energy sources. A sensor control circuit has a plurality of sensors configured to detect the DC signals from the plurality of transducers. A DC-to-DC converter is configured to supply an output voltage. A plurality of switches, each switch coupled between the DC-to-DC converter and a corresponding transducer of the plurality of transducers. The sensor control circuit enables one switch of the plurality of switches and disables the other switches of the plurality of switches based on a priority criterion.
