In this paper, a study on the performance of Wireless Power Transfer (WPT) systems embroidered onto denim using conductive threads is presented. A 30 mm radius transmitting (TX) element and an embroidered receiving (RX) element were fabricated on an FR-4 PCB and on textile using conductive threads, respectively. Different sewing layers (up to four) and angles were studied. The measured results show that a CSCMR system with four layers of embroidered elements achieves the optimal performance when sewing angles of 0° and 135° are layered on top of each other, providing a Power Transfer Efficiency (PTE) of 58%. Furthermore, liquid metal nanoparticles were added between the four-layer design and this increased the PTE to 68%.
