A method for manufacturing an apparatus for generating electrical energy may include; disposing a nanowire including a piezoelectric material on a first electrode, disposing an active layer, which is electrically connected to the nanowire, on the first electrode, disposing an insulating film on the nanowire, disposing a conductive layer on the active layer, and disposing a second electrode in proximity to the nanowire and substantially opposite to the first electrode.

Method for manufacturing an apparatus for generating electric energy

An apparatus for storing energy may include: a plurality of nanowire cells electrically connected to each other; and a storage for storing electrical energy generated from the nanowire cells. Each of the plurality of nanowire cells may include: first and second electrodes disposed at an interval; and a nanowire, which is disposed between the first and the second electrodes and made of a piezoelectric material. The plurality of nanowire cells may be electrically connected, so that voltage or current may be increased. Therefore, wireless recharging of the storage connected to the nanowire cells with electrical energy may be enabled.

Apparatus for storing energy and method for manufacturing the same

An apparatus for generating electrical energy may include; a first electrode, a second electrode spaced apart from the first electrode, the second electrode having a substantially planar flat plate shape, a conductor which electrically connects the first and second electrodes, and a nanowire disposed on the first electrode, the nanowire including a deformable piezoelectric material, wherein a Schottky contact is formed between the nanowire and the second electrode as the nanowires is deformed.

Apparatus for generating electrical energy using electrically connected nanowire and active layer and method for manufacturing the same

An apparatus for generating electrical energy including a first electrode, a second electrode and one or more nanowires, and a method for manufacturing the apparatus for generating electrical energy. The second electrode may have a concave portion and a convex portion. The first electrode and the nanowire are formed of different materials. The nanowire is formed on the first electrode and is positioned between the first electrode and the second electrode. Because the nanowire is formed on the first electrode, the nanowire may be grown vertically and the uniformity and conductivity of the nanowires may be improved. When a stress is applied to the first electrode or the second electrode, the nanowire is deformed and an electric current is generated from the nanowire due to a piezoelectric effect of the nanowire and a Schottky contact between the nanowire and the electrode which makes contact with the nanowire. Accordingly, when the apparatus for generating electrical energy is bent or pressed in part, electrical energy is generated in response to the applied stress.
