<p>This energy conversion device is equipped with a vibration energy harvester and a rectifier circuit. The vibration energy harvester outputs an alternating-current voltage by means of electromagnetic induction caused by displacement of the position of a coil block relative to a magnet block in a prescribed direction. The vibration energy harvester is equipped with multiple elastic body sections which deform more easily in the prescribed direction than in a direction orthogonal to the prescribed direction and which connect a movable section having the magnet block or the coil block to a support section. The multiple elastic body sections are arranged along the direction orthogonal to the prescribed direction on either end of the movable section in the prescribed direction. The rectifier circuit is a voltage doubler rectifier circuit wherein different capacitors are charged when the polarity of the alternating-current voltage is positive and when the polarity is negative.</p> |
