The energy harvester comprises a first electrode, a second electrode and a load. The first electrode comprises a first semiconductor material. The second electrode comprises at least one of a second semiconductor material and a metal material. The load is provided between the first and second electrodes and is electrically connecting a first end of the first electrode and a first end of the second electrode. Relative movement of the first electrode and the second electrode causes a second end of the first electrode and a second end of the second electrode to be in contact with each other and subsequently apart from each other generating a current flow through the load.
