This project investigates the use of laser-cut and 3D-printed auxetic patterns as a new strategy for designing textile-based stretch sensors for wearable applications. We explored how different auxetic geometries can be integrated into e-textiles to create flexible, highly sensitive sensors capable of reliably capturing body movement.

Using two biostable auxetic patterns, we fabricated stretch sensors directly on fabric and evaluated their impedance response during repeated cycles of stretching and relaxation. By 3D printing conductive filaments onto textiles in auxetic configurations, we achieved stable and repeatable stretch-sensing performance.
