Novel inkjet-printed ferromagnetic-based solutions for miniaturized wireless power transfer (WPT) inductors and antennas

In this work, we have shown the feasibility of inkjet-printed ferromagnetic material on a flexible, low cost, paper substrate for miniaturization of planar spiral inductors, which can be extended to compact printed transformer designs for wireless power transmission applications as well as other designs such as antennas and reconfigurability by way of tunable inductors for antenna tuning.
