Textile resonators using a sintered metal conductor for wearable MR-WPT with high efficiency and wearability

This article presents an analysis of the performance of the conductive patterns using a sintered metal conductor (SMC) in textile resonators for wearable applications of magnetic resonant wireless power transfer (MR-WPT). The SMC has advantages in physical and electrical performances. This study compared resonators fabricated with two conductive materials, including a silver paste, as materials for a wearable conductor (MWC). To verify the performance of textile resonators in the MR-WPT, we configured the proposed system consisting of symmetric transmitter and receiver. In the measurement results, the maximum transfer efficiency of the MR-WPT with the SMC is 43.19% at 10 mm, which is much higher than the MWC, and it maintains the superb durability and flexibility for wearable applications.
