Abstract
A vibration energy harvester includes: a pair of electrodes provided so as to face opposite each other, with at least one of the pair of electrodes allowed to move; and an ion gel provided between the pair of electrodes, which is formed by using an ionic liquid, wherein: as an external vibration causes the electrode to move along a direction in which a distance between the pair of electrodes changes, power is generated through a change in an area of an electric double layer formed on two sides of an interface of each electrode and the ion gel.
