Abstract
In an energy harvesting system, a power extraction circuit extracts electrical power from an environmental power source susceptible of providing a level of power that fluctuates. An electrical power storage device stores the electrical power extracted from the environmental power source by the power extraction circuit. A sensing circuit provides an indication of a level of power that the power extraction circuit can extract from the environmental power source. A controlled switch circuit electrically decouples the power extraction circuit from the electrical power storage device when the indication indicates that the level of power that the power extraction circuit can extract from the environmental power source is insufficient for the power extraction circuit to charge the electrical power storage device. This prevents leakage of harvested power.
