Patents by Inventor Dau Min Zhou

Dau Min Zhou has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9592396
    Abstract: The invention is directed to a method of bonding a hermetically sealed electronics package to an electrode or a flexible circuit and the resulting electronics package that is suitable for implantation in living tissue, for a retinal or cortical electrode array to enable restoration of sight to certain non-sighted individuals. The hermetically sealed electronics package is directly bonded to the flex circuit or electrode by electroplating a biocompatible material, such as platinum or gold, effectively forming a plated rivet-shaped connection, which bonds the flex circuit to the electronics package. The resulting electronic device is biocompatible and is suitable for long-term implantation in living tissue.

  • Patent number: 8489202
    Abstract: An implantable electrode having a strong, adherent surface coating of iridium oxide or titanium nitride on a platinum surface, where the platinum surface has a surface area of at least five times that of a smooth shiny platinum surface of the same geometry. The iridium oxide coating may be formed on platinum by a physical deposition process, such as sputtering. A gradient coating of iridium oxide ranging in composition from pure platinum to pure iridium oxide is produced by sputtering.

  • Patent number: 8389434
    Abstract: An improved platinum and method for manufacturing the improved platinum wherein the platinum having a fractal surface coating of platinum, platinum gray, with a increase in surface area of at least 5 times when compared to shiny platinum of the same geometry and also having improved resistance to physical stress when compared to platinum black having the same surface area. The process of electroplating the surface coating of platinum gray comprising plating at a moderate rate, for example at a rate that is faster than the rate necessary to produce shiny platinum and that is less than the rate necessary to produce platinum black. Platinum gray is applied to manufacture a fuel cell and a catalyst.
