  • Patent number: 9929336
    Abstract: A self-powered generator is provided. The generator includes a piezoelectric nanorod member layer that includes a first layer; a second layer; and a plurality of piezoelectric nanorods disposed between the first and second layers. The piezoelectric nanorod is a biaxially-grown nanorod. When mechanical energy is applied from an outside, an upper half and a lower half of each of the plurality of piezoelectric nanorods generate piezoelectric potentials having opposite polarities, the upper half and the lower half being on both sides of a longitudinal axis along an axis perpendicular to the longitudinal axis.

  • Patent number: 9112076
    Abstract: A glass substrate manufacturing method of the present invention comprises forming a multi-porous structure layer which comprises nano-size pores at a surface of a glass substrate by etching the surface of the glass substrate with hydrofluoric (HF) acid or an etchant substituting for fluoride. Unlike related art methods, the glass substrate forms no additional coating layer, uses no harmful chemical material, and is given anti-reflection, anti-fogging, and super-hydrophilic characteristics through a simple process at a relatively low temperature. The glass substrate is effectively applied to various applications requiring high light transmission such as a protective filter for a display device, a solar cell, a mobile communication device, glass of a building structure, and an optical element lens.
