NANO GENERATOR USING PLA PIEZOELECTRIC MATERIAL OF NANOFIBER WEB TYPE BY ELECTROSPINNING

摘要

The present invention relates to a nano-generator, and more specifically, to a nano-generator using a PLA piezoelectric sensor of a nano-fiber web form obtained by electrospinning which folds a PLA piezoelectric material realized in a nano-fiber web form by electrospinning poly lactic acid at least twice to allow top portions of a nano-fiber web to face each other and allow bottom portions to face each other to form a folded PLA nano-fiber web. Then a flexible parallel electrode unit is connected to each folded layer of the folded PLA nano-fiber web to transmit an electrical signal generated by the folded PLA nano-fiber web by a piezoelectric effect when applying a pressure by a signal transfer unit made of conductive fabric to store the electrical signal in an energy storage means such as a capacitor to realize a small autonomous generator at low costs while retaining a property of the fabric.
