A wireless power link on leather for applications in the clothing industry

摘要

This paper presents a new wireless power link fabricated by using a conductive non-woven fabric on a leather substrate, thus resulting in a prototype that can be easily embedded in wearable accessories such as fashion bags. More in detail, in the fabricated prototype (which was designed to work in the ISM band 433.05 - 434.79 MHz), the power transfer was implemented by exploiting a magnetic coupling between two planar resonators. The results related to the characterization of the fabricated wireless power link are presented and discussed. In particular, from experimental data, a power transfer efficiency of about 69 % is demonstrated.
