Crosstalk effect in a fabric circuit developed for multi-connection of sonar sensors

The aim of this study is to analyze the crosstalk effect within e-textile structure. In e-textiles, induced signals acting as a noise source are resulting in a crosstalk and lack of signal integrity between conductive lines. In this study, in order to analyze crosstalk effect within e-textile circuit, e-textile structure was firstly developed according to multi connection of sonar sensors by using conductive yarns. Then, signals ranging from 4 kHz to 400 kHz were applied on conductive yarns used as transmission lines in different configurations like GS (Ground-Signal), GSG (Ground-Signal-Ground) etc. Finally, the outputs of transmission lines and crosstalk effect in neighboring lines (from 1st to 6th conductive yarn) were measured and analyzed in decibels. Results showed that due to the configuration as the distance between conductive yarn increases, crosstalk decreases.
