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. © 2017 Wiley Periodicals, Inc.
