US 8,803,406 B2 · Flexible nanocomposite generator and method for manufacturing the same

Abstract

There are provided a flexible nanocomposite generator and a method of manufacturing the same. A flexible nanocomposite generator according to the present invention includes a piezoelectric layer formed of a flexible matrix containing piezoelectric nanoparticles and carbon nanostructures; and electrode layers disposed on the upper and lower surfaces of both sides of the piezoelectric layer, in which according to a method for manufacturing a flexible nanocomposite generator according to the present invention and a flexible nanogenerator, it is possible to manufacture a flexible nanogenerator with a large area and a small thickness. Therefore, the nanogenerator may be used as a portion of a fiber or cloth. Accordingly, the nanogenerator according to the present invention generates power in accordance with bending of attached cloth, such that it is possible to continuously generate power in accordance with movement of a human body.
