Applying Tumor Treating Fields (TTFields) to a Subject's Body Using Electrodes Having a Fluoropolymer Layer Disposed on Successive Strata of Nickel, Palladium, and Gold

원문 (중국어)

Alternating electric fields (e.g., TTFields) can be applied to a subject's body using a pair of electrode assemblies, each of which includes a flexible insulating substrate and a plurality of conductive pads disposed on a front side of the flexible insulating substrate. Each of the conductive pads includes a layer of nickel, a layer of palladium disposed on a front side of the layer of nickel, and a layer of gold disposed on a front side of the layer of palladium. A plurality of flexible polymer regions made from Poly(VDF-TrFE-CtFE), Poly(VDF-TrFE-CFE), and/or Poly(VDF-TrFE-CFE-CTFE) are disposed on the front side of the conductive pads. When an AC voltage is applied between the pair of electrode assemblies, an AC current will be capacitively coupled into the subject's body, which will induce the alternating electric fields in the subject's body.
