The intelligent systems of smart textile should contain flexible electronics, for example, sewn or stitched textile elements that function as conductive traces, sensor elements, electrodes or switches. The experiments for development of sewn touch and push switches are performed. For this reason silver coated multifilament polyamide and multifilament stainless steel yarns were used and their properties and suitability tested. Tests include the changes of electrical resistance of yarns during tension, measurements of yarn voltage loss at 50 mA current; experiments to assess the yarn suitability for sewing; reliability tests of switches during use. |
