Abstract
Using different stitch patterns can allow a single conductive yarn to take on varying electrical properties and serve different functions in an electrical circuit. However, the relationship is not so well understood due to the vast variety of stitch patterns available. We seek to contribute to this understanding by characterizing 13 basic stitch patterns with potential for strain sensing. We found that changing the stitch pattern increased the gauge factor (sensitivity) by 7.16 times, the working range by 2.90 times, and the resistance by 3.50 times. Rib 1x1 and Interlock x2 were promising strain sensor candidates with high sensitivity and working ranges, while Linen Stitch and Full Cardigan were promising interconnect candidates with low sensitivity. This is our first step towards the design of wearable sensors for human motion sensing.
