The field of electronic textiles is still relatively new and extending due to technology miniaturisation. In this article, the integration of an ultrasonic sensor into a textile structure was realised and analysed in order to develop a system able to help visually impaired people. The performance of ultrasonic sensors was tested by means of five different conductive yarns used as transmission lines, in three different configurations for the purpose of detecting the eventual existing off disturbances and their values. Finally, the influence of the conductive yarn type on the performance of the ultrasonic sensor was discussed. The results highlighted that the linear resistance of conductive yarn has a strong influence on the sensor’s signal quality.

Tekstylne wyroby tekstroniczne są ciągle nową dziedziną wymagającą intensywnych badań. W artykule opisano badania związane z integracją czujników ultradźwiękowych w odzieży tekstronicznej, które mogą być pomocne np. przy identyfikacji przedmiotów przez niewidomych. Zachowanie tych czujników badano przy zastosowaniu pięciu różnych przędz przewodzących stosowanych jako linie przesyłowe, w trzech różnych konfiguracjach dla kreślenia ewentualnie występujących zakłóceń i ich wielkości. Po dyskusji wyników stwierdzono, że wartość rezystancji liniowej stosowanych przędz odgrywa istotna rolę w jakości sygnałów przekazywanych przez czujniki ultradźwiękowe.
