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

Bu çalışmanın amacı e-tekstil yapılarında meydana gelen diyafoni etkisini analiz etmektir. E-Tekstillerde, endüklenen sinyal, bozucu bir etki yaratmakta olup iletken iplikler arası sinyal diyafonisi oluşturmakta ve sinyal bütünlüğünü bozmaktadır. Bu çalışmada; sinyal diyafoni etkisini e-tekstil yapılarında analiz etmek için, e-tekstil yapısı öncelikle sonar sensörlerin çoklu bağlantı şekline göre iletken iplikler kullanılarak oluşturulmuştur. Sonrasında, 4 kHz’den 400 kHz’e kadar değişen aralıklardaki sinyaller farklı kombinasyonlarda (GS (Toprak sinyali - Verici sinyal), GSG gibi) iletim hattı olarak görev alan iletken ipliklerin üzerine uygulanmıştır. Son olarak da, iletim hattı çıktıları ve komşu hatlarda (1’den 6. iletken ipliğe kadar) meydana gelen sinyal diyafonisi ölçülmüş ve desibel cinsinden analiz edilmiştir. Sonuçlar, konfigürasyona bağlı olarak iletken iplikler arası mesafenin artmasıyla sinyal diyafonisinin azaldığını göstermiştir.

Sonar sensörlerin çoklu bağlantısı için geliştirilmiş bir kumaş devresinde diyafoni etkisi

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.
