TRIBOELECTRIC ENERGY GENERATOR USING CONTROL OF DIPOLE POLARIZATION DIRECTION AND METHOD OF FABRICATING THEREOF

摘要

Provided are a triboelectric energy generator using a control of a dipole polarization direction and a method of fabricating the same. The present invention controls a direction of a charging property generated by friction through a control of a dipole polarization using a ferroelectric or piezoelectric property of a material, and by using this control, the present invention is related to a triboelectric energy generator in a disk type in which a frictional charging material is slidable on a thin film only using control of a dipole polarization without need of an additional patterning process and output power is improved.

1. A triboelectric energy generator using a control of a dipole polarization direction, comprising:
a lower electrode layer; a ferroelectric or piezoelectric material layer disposed on the lower electrode layer; and a frictional charging material layer which is disposed on the ferroelectric or piezoelectric material layer in a contact state, is movable, and is an upper electrode, wherein the ferroelectric or piezoelectric material layer is divided into two or more regions in a direction parallel to a surface of the lower electrode layer, in the two or more regions of the ferroelectric or piezoelectric material layer, each region is polarized so that dipole polarization directions of the regions disposed next to each other are different from each other, and triboelectric energy is generated by continuous charging and friction caused by sliding or rotating the frictional charging material layer.
