Abstract
A system for recovering energy from a sensor couples a battery to an inductive device in the sensor for a period of time, such that a current flows through the inductive device from the battery during the time period. The connections of the inductive device are then reversed for a second period of time. During the second time period, a current flow resulting from energy stored in the inductor is allowed to flow back to the battery, such that a portion of the energy from the inductor recharges the battery during the second period of time.
