Tribo-induced charges based tension sensing yarns

Abstract

A tribo-induced charges based tension sensing yarn (TCTSY) system is provided, including a primary conductive filament having a first dielectric layer coated around an outer surface of the primary conductive filament; and a secondary conductive filament. When outer surfaces of the primary and secondary conductive filaments contact each other, charges are transferred between the contacted outer surfaces of the primary and secondary conductive filaments. When an axial tensile force is applied to the TCTSY system, a potential difference is generated by the transferred charges between the primary conductive filament and the secondary conductive filament, indicating a magnitude of the applied force. The TCTSY system can be integrated into warp and weft yarns of the fabric with weaving pattern, enabling fabric with distributed weft and warp-axial tension sensing where any two crossed TCTSY systems are configured to measure tension distribution over an area around crossed point of the fabric.
