Dielectric having nanoring structure carbon nanotube and Energy harvesting device using the same

摘要

The present invention relates to a method for manufacturing a dielectric composite including a nanoring-structured carbon nanotube, which disperses nanoring-structured carbon nanotubes with excellent dispersibility and conductivity in a dielectric with an excellent strain rate to manufacture a dielectric composite with high capacitance and a high strain rate, and applies the dielectric composite to an energy harvesting device, thereby increasing an electric energy generation efficiency; and an energy harvesting device using the dielectric composite including a nanoring-structured carbon nanotube. According to the present invention, the energy harvesting device using a dielectric composite including a nanoring-structured carbon nanotube comprises: an electret; the dielectric composite spaced apart from the electret and including a nanoring-structured carbon nanotube; and a deformation frame disposed close to the dielectric composite. When the deformation frame is extended in a horizontal direction, the dielectric composite is also extended and a distance between the electret and the dielectric composite is decreased. When the deformation frame is returned to an original state, the dielectric composite is restored to an initial state and the distance between the electret and the dielectric composite is restored to an initial state.
