The article describes research into the transmission properties of textile signal lines (TSLs) made using ultrasonic welding technology. The presented TSLs are made from electroconductive, nickel coated, fabric strips welded between non-conducting textile layers. The article presents an analysis of the usability of the ultrasonic welding method for creating TSLs. This analysis shows that direct welding of an electroconductive path with the substrate increases its linear resistance, making it impossible to create a properly functioning line. This article presents an alternative method of creating the line using ultrasound welding technology.

This paper presents results of research on poppers used as electrical connectors connecting fragments of textile signal lines. These lines can be used in intelligent clothing for connecting electronic modules implemented in it. Intelligent (smart) clothing can be used, among others, in the health monitoring of the elderly, newborn babies, or people working in hazardous conditions, for example, firefighters and soldiers. The aim of the present study was to examine the usefulness of poppers, widely used in clothing, as electrical connectors connecting parts of the textile signal lines designed for transmission of high-speed digital signals. The paper presents examples of measured parameters characterizing transmission properties of two fragments of the coplanar, textile transmission line connected to each other using conventional poppers. The presented measurement results contain the so-called s parameters, characteristic impedance of the poppers, and eye measurements characterizing distortions of digital signals passing through the tested line. In the article, the effect of temperature and humidity of air surrounding the tested poppers on their characteristic impedance was also presented. This property and its stability are important in signal lines designed for high-speed data transmission.

The article describes a new kind of textile transmission line which might be widely used, among others, in smart clothing. This line consists of a textile substrate in the form of fabric, sewn with paths made from electrically conductive fabric. The arrangement of electrically conductive paths in the line proposed makes it easy to obtain the possibility of impedance changes in a wide range of its values (potentially giving the possibility to obtain an impedance equal to 50 Ω), regardless of the type of fabric used as a substrate. The paper presents examples of measurement results of characteristic impedance of the line affecting its transmission properties. It also presents an impact study of the type of stitches fastening electrically conductive paths and the inaccurate creation of the line on the value of the characteristic impedance. The studies presented are based on real measurements and computer simulation using CST Studio software.

W artykule opisano nowy rodzaj tekstylnej linii transmisyjnej mogącej znaleźć szerokie zastosowanie w tekstronice. Linia ta składa się z tekstylnego podłoża, na które naszyto ścieżki wykonane z tkaniny elektroprzewodzącej. Rozmieszczenie ścieżek elektroprzewodzących w proponowanej linii umożliwia łatwe uzyskanie impedancji równej 50 Ω, niezależnie od rodzaju tkaniny użytej na jej podłoże. W artykule przedstawiono wyniki pomiarów impedancji mającej wpływ na właściwości transmisyjne linii. Przedstawiono badania wpływu sposobu przyszycia ścieżek elektroprzewodzących linii oraz błędów jej wykonania na wartość jej impedancji.
