Assessing the performance of inkjet-printed coils on paper substrate for WPT

In recent years, wireless power transmission (WPT) has received special attention as a very valuable and convenient technology to power a wide range of equipment and devices, such as mobile phones, laptops, integrated circuits, electric vehicles[1], medical devices and other passive sensors. Magnetic resonance-based WPT is a directional coupled type of near-field power transmission suitable for short distances. Design of inductive coupling coils is crucial to the performance of WPT[2]. The aim of this work is to assess the potential of inkjet printing technology for cheaper and faster prototyping of inductively coupled coils on paper substrate.
