Abstract: The invention performs a new electrode structure that increases the surface area of the electrode. An electrode structure comprises a conductive part, a grass-like dielectric material on the conductive part, and a conductive layer on the grass-like dielectric material. The conductive part and the conductive layer is electrically connected to each other.
