RESi: A Highly Flexible, Pressure-Sensitive, Imperceptible Textile Interface Based on Resistive ...
summary
A new yarn combines a metallic core with a carbon‑based polymer coating so that two intersecting yarns form a single‑layer resistive pressure sensor that drops resistance under load. Tests show sensitivity primarily between 0 and 0.6 N, tensile strength varies by thickness, and even an 80 µm yarn measures ~9 Ω/m. Prototypes include a 6×6 machine‑sewn pants patch, a 1024‑sensor woven handbag corner, a flexible PCB readout, solderable connections, plus a web API for rapid prototyping; current limits: no stretchability and no dyeing.
