Abstract:
A conductive structure is fabricated on a substrate (either flexible or rigid) by first printing a precursor seed layer of a conductive ink, then electroplating a highly conductive metal such as Cu or Ag onto the precursor. The plated layer has a conductivity approaching that of the bulk metal. To improve the uniformity of plating, an intervening layer of electroless metal may be deposited onto the precursor prior to electroplating. The structure may be used for applications such as coils used in a wireless power transfer system.
