Purpose – By means of measurement and modelling, evaluate frequency dependent per-unit-length parameters of conductive textile transmission line (CTTL) for wearable applications and study deterioration of these parameters when CTTL is subjected to washing.
Design/methodology/approach – The studied transmission line is made of Nickel/Copper (Ni/Cu) plated polyester ripstop fabric and is subjected to standard 60oC cycle in a commercial off-the-shelf washing machine. The per-unit-length parameters (resistance and inductance) and characteristic impedance of the line are extracted from measurements before and after washing. Using the measurement data an equivalent circuit is created to model the degradation of the line. The circuit is then integrated in a three-dimensional Transmission Line Matrix (TLM) model of the transmission line.
Findings – Both an electrical equivalent circuit and a TLM model are developed describing the degradation of the conductive textile when washed. A severe deterioration of the electrical parameters of the line is noticed. Experimental and modelling results are in good agreement in the addressed frequency band.
Research limitations/implications – Analysis is performed for frequencies up to 10 MHz. The developed TLM model can be used to conduct parametric studies of the CTTL. To counteract the degradation of the line, protective coating is to be considered in further studies.
Originality/value – Experimental and simulation based characterization of the conductive textile transmission line when subjected to washing cycles.
