  • Publication number: 20240084465
    Abstract: A modification method of an anode for hydrogen production via electrolysis, the anode for hydrogen production via electrolysis and use thereof are provided. The modification method of the anode for hydrogen production via electrolysis includes providing an anode substrate which can be used for hydrogen production via catalytic electrolysis; and depositing a plurality of silver nano particles on the active surface of the anode substrate to form a silver nano layer, wherein gaps are present between the silver nano particles, and a part of the active surface is exposed from the gaps. In the modification method provided by the present application, the silver nano layer covers on the surface of the anode substrate, and chlorine ions are adsorbed onto the surface of silver in the process of hydrogen production via electrolysis to form a chlorine removal layer.

  • Patent number: 11712204
    Abstract: Systems and methods are presented for a swallowable pH sensor made entirely of edible and digestible materials. A substrate is provided and an electrical circuit pattern is printed on a top surface of the substrate. The electrical circuit pattern includes a plurality of interdigitated electrodes and an antenna portion. The substrate is rolled into a cylindrical form such that the interdigitated electrodes are positioned on an outermost layer of the rolled substrate. The rolling of the substrate also causes the antenna portion of the electrical circuit pattern to form into a coil shape.

  • Patent number: 10468203
    Abstract: Systems and methods are described for an edible capacitive power source such as a supercapacitor device. The capacitive power source includes an anode electrode, an anode current collector, a cathode electrode, and a cathode current collector, arranged in layers with a separator layer positioned between the anode electrode and the cathode electrode forming a symmetrical electrical double-layer capacitor. The anode electrode, the anode current collector, the cathode electrode, the cathode current collector, and the separator layer are all constructed of non-toxic, edible materials. The packaging material, the conductive anode tab, and the conductive cathode tab are all also constructed of non-toxic, edible materials forming a completely edible capacitive power source package.
