    • 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.
    • 一种用于产生包括第一电极,第二电极和一个或多个纳米线的电能的装置,以及用于制造用于产生电能的装置的方法。 第二电极可以具有凹部和凸部。 第一电极和纳米线由不同的材料形成。 纳米线形成在第一电极上并且位于第一电极和第二电极之间。 因为在第一电极上形成纳米线,所以可以垂直生长纳米线,并且可以提高纳米线的均匀性和导电性。 当对第一电极或第二电极施加应力时,由于纳米线的压电效应和纳米线与电极之间的肖特基接触,纳米线变形并且从纳米线产生电流,其与 纳米线 因此,当用于产生电能的装置弯曲或部分地被按压时,响应于施加的应力而产生电能。
