Patent ID: 8354871

Claim:
An energy harvester system, comprising: an energy harvesting module; an energy storage element; a comparator wherein the comparator comprises: a first input connector; a second input connector; an input power connector; and an output connector, wherein the comparator is connected to the energy harvesting module via the first input connector, wherein the comparator is connected to the energy storage element via the second input connector, and wherein the input power connector is connected to the energy harvesting module such that the comparator is powered by the energy harvesting module when a first voltage applied to the first input connector by the energy harvesting module is higher than a threshold voltage, wherein the output connector outputs an output voltage, a switch transistor, wherein the switch transistor comprises a gate, a switch input, and a switch output, wherein the output connector is connected to the gate of the switch transistor, wherein the energy harvesting module is connected to the switch input, and wherein the energy storage element is connected to the switch output; wherein when the first voltage is higher than a second voltage applied to the second input connector by the energy storage element, the output voltage connected to the gate of the transistor allows power to flow from the energy harvesting module to the energy, and wherein the comparator only consumes power when the first voltage is higher than the threshold voltage.
