Abstract
Triboelectric nanogenerators are provided that are textile-based, combine embroidery, silanizing agents, highly networked conductive nanoparticles, and a conformable electronegative layer, and can produce a stable energy source with high power density. Electronic textiles are also provided that utilize such triboelectric nanogenerators to convert the biomechanical energy of a wearer into electrostatic energy that can power electronic devices coupled with the triboelectric nanogenerator. Methods of manufacturing the triboelectric nanogenerators and related electronic textiles are also provided.
Claims20
An triboelectric nanogenerator comprising:
- a first electrode layer affixed to a first textile substrate;
- a second electrode layer affixed to a second textile substrate;
- and
- an electronegative layer positioned on or over the second electrode layer and in a position relative to the first electrode layer such that the first textile substrate is able to undergo friction with the electronegative layer;
- wherein each of the first and second electrode layers comprises a plurality of conductive nanoparticles arranged on a surface thereof and are electrically charged by the friction between the first textile substrate of the first electrode layer and the electronegative layer.
A method of manufacturing an e-textile comprising:
- affixing one or more triboelectric nanogenerators to a textile capable of harvesting electrostatic energy from a wearer's motion to power one or more electronic devices;
- wherein the one or more triboelectric nanogenerators comprises:
- a first electrode layer affixed to a first substrate,
- a second electrode layer affixed to a second substrate,
- an electronegative layer positioned on or over the second electrode layer and in a position relative to the first electrode layer such that the first substrate is able to undergo friction with the electronegative layer, and
- a component positioned over the first electrode layer and coupled with both the first electrode layer and the second electrode layer,
- wherein each of the first and second electrode layers comprises a plurality of conductive nanoparticles arranged on a surface thereof and are electrically charged by the friction between the first substrate of the first electrode layer and the electronegative layer.
