StretchEBand: Enabling fabric-based interactions through Rapid Fabrication of Textile Stretch ...
summary
Fabric-based stretch sensors are fabricated on a household sewing machine using conductive filament yarn (silver‑plated nylon) and stitched patterns; five yarns are evaluated and the zig‑zag/6‑axis stitches prove most reliable. Electrical resistance is measured 37 measurements × 10 cycles up to ~170% strain, revealing drift/hysteresis with repeated use. Stitch width/length are derived by formula to match material elasticity, and a user study with 12 participants shows sensor length doesn't affect control but stiffer materials give finer, faster input. Prototypes work for phone, watch, cushions and car seats but need durability improvements.
