Abstract
Example embodiments relate to an energy harvester using triboelectricity, and to an apparatus including the energy harvester. The energy harvester may include a first structure having a first triboelectric material, a second structure having a second triboelectric material, and a closed structure isolating friction surfaces of the first and second triboelectric materials from external environment. The energy harvester may further include a filling material in the closed structure. The filling material may have an electric charge. The filling material may have a viscosity. At least a portion of the closed structure may include an elastic material.
Claims25
An energy harvester comprising:
- a first structure including a first triboelectric material;
- a second structure including a second triboelectric material configured to generate electricity by friction with the first triboelectric material;
- a closed structure configured to isolate friction surfaces of the first and second triboelectric materials from environmental agents;
- and
- a filling material in the closed structure in contact with the first and second triboelectric materials and having a plurality of electric charges, the filling material being configured to increase an electrification efficiency of the first and second triboelectric materials.
An energy harvester comprising:
- a first structure including a first triboelectric material;
- a second structure including a second triboelectric material generating electricity by friction with the first triboelectric material;
- and
- an intermediate material between the first and second structures and having an electric charge,
- wherein the intermediate material is configured to move outward from a gap between the first and second structures when the gap between the first and second structures is decreased, and the intermediate material is configured to fill the gap between the first and second structures when the gap between the first and second structures is increased.
