Abstract
A vibration-driven energy harvesting device includes a vibration-driven energy harvesting element that generates power according to vibrations of an electrode; an output unit that, when connected to a load resistor, extracts power generated by the vibration-driven energy harvesting element; a judgment unit that judges whether or not a power value of the power is greater than a predetermined threshold value; a determination unit that determines an input impedance of the output unit based on a judgment result obtained by the judgment unit; and an adjustment unit that adjusts the input impedance of the output unit according to a determination made by the determination unit.
