Electrical characterization of textile transmission lines

TLDR

The paper presents electrical characterization and modeling of conductive textiles. A dedicated measurement setup was developed to reliably connect textile samples to equipment cables. The study determined geometrical and fabrication tolerances, high‑frequency properties up to 6 GHz for four textile types, realized transmission lines with controlled impedance, and showed they can operate up to 1.2 GHz (10 cm) and 120 MHz (100 cm).

Abstract

In this paper, electrical characterization and modeling of conductive textiles are presented. A dedicated measurement setup has been developed to allow reliable connection of the textile samples with the equipment cables. Geometrical fabric structures and fabrication tolerances as well as high frequency properties up to 6 GHz for four types of textiles have been determined. Transmission lines with controlled characteristic impedance have been realized enabling the characterization of typical line attenuation factors. This work shows that textile transmission lines can be used for frequencies up to 1.2 GHz and 120 MHz with the maximal lengths of 10 and 100 cm, respectively.
