Pressure Sensors for 3D Nonwoven Assemblies by Using Novel Spacer Stitching Technology

Textile-based sensors are increasingly popular for wearable technology due to their affordability, lightweight, flexibility, and compatibility with diverse body shapes, offering a promising alternative to traditional solid-state sensors. These sensors can be crafted with conductive polymers, threads, or fabrics for various applications. This study explores a unique sewing method, spacer stitching, which prevents compression during stitching to preserve material thickness. This approach was used to sew conductive thread onto spacer and sandwich-structured nonwoven fabrics, creating a pressure sensor that enhances thermal insulation in clothing and suits spacer fabric applications.
