1. An energy harvester comprising:
- a mass;
a first substrate and a second substrate spaced apart from the first substrate, wherein one of the first substrate and the second substrate is connected to the mass;
a first electrode disposed on the first substrate and a second electrode disposed on the second substrate; and
an energy generator connected between the first electrode and the second electrode, wherein the energy generator generates electric energy upon a relative movement between the first substrate and the second substrate caused by a movement of the mass,wherein the energy generator comprises a triboelectric generator,wherein the triboelectric generator comprises;
a first triboelectric layer provided on the first electrode and comprising a first dielectric or a metal; and
a second triboelectric layer provided on the second electrode and comprising a second dielectric that is different from the first dielectric.

23. A mobile device comprising:
-
a mobile device body; a support which supports the mobile device body; and an energy harvester provided in at least one of the mobile device body and the support, wherein the energy harvester generates electric energy upon application of a mechanical force on at least one of the mobile device body, wherein the energy harvester comprises; a substrate having a tube shape and a cavity formed therein; a triboelectric layer provided on an inner surface of the substrate; at least one first electrode and at least one second electrode disposed on the substrate; and at least one mass which is movable along a longitudinal direction of the cavity inside the triboelectric layer in the cavity, wherein when the at least one mass and the triboelectric layer rub against each other or a distance difference occurs between the at least one mass and the triboelectric layer, electric energy is generated between the at least one first electrode and the at least one second electrode due to a charge density difference occurred between the at least one mass and the triboelectric layer. - View Dependent Claims (24, 27)
