1. A structure of an artificial electronic retina comprising an array of a plurality of photoelectric units, each photoelectric unit including:

  • an electronic photosensitive element;

    a microelectrode disposed on a top surface of the electronic photosensitive element and electrically connected to the electronic photosensitive element;

    a layer of a light-permeable conductive material disposed in an independent manner on the top surface of the electronic photosensitive element in each photoelectric unit and surrounding the microelectrode, an inner surface of the layer of the light-permeable conductive material abutting against an outer surface of the microelectrode, and the layer of the light-permeable conductive material electrically connected to the microelectrode and the electronic photosensitive element;

    an electronic circuit disposed on the top surface of the electronic photosensitive element and surrounding the layer of the light-permeable conductive material, and an inner surface of the electronic circuit abutting against an outer surface of the layer of the light-permeable conductive material; and

    a base including sidewalls and a bottom wall, the sidewalls abutting against sidewalls of bases of neighboring photoelectric units and forming a chamber with the bottom wall;

    wherein the electronic photosensitive element, the microelectrode, the layer of the light-permeable conductive material and the electronic circuit are received in the chamber, a bottom surface of the electronic photosensitive element abuts against the bottom wall of the base, both an outer surface of the electronic photosensitive element and an outer surface of the electronic circuit abuts against inner surfaces of the sidewalls of the base.
