▎ 摘　　要

NOVELTY - The 3D electronic device has a fractal structure that is provided with an array with multiple radial elements which are interconnected at and radially extending from a center of the device. The spiral element encircles the center and any spiral elements are located radially inward. The fractal structure is applied to a 3D surface, a time-dynamic surface, or a flexible surface. The fractal structure includes an organic, n-type doped graphene hybrid composite material at cross-junctions of the spiral and radial elements. The hemispherical photodetector device has photodetectors at cross-junctions of the spiral and radial elements. USE - Three-dimensional (3D) electronic device e.g. electronic contact lens device (claimed). ADVANTAGE - The 3D electronic device has improved resistance to mechanical deformations, improved mechanical adaptability, and improved damage tolerance due to the fractal structures. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method of producing a three-dimensional electronic device; and (2) an electronic contact lens device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a fabrication method to yield a 3D electronic device.
