Abstract:In this study, to fabricate a soft conductive re-entrant (RE) strain sensor using a fused filament fabrication three-dimensional (3D) printer, carbon/thermoplastic polyurethane (TPU) filaments with three carbon materials—graphene (GR), carbon fiber (CF), and carbon black (CB)—were analyzed. The 3D printing performance of carbon/TPU was evaluated to confirm the applicability to 3D printing. Firstly, the results of the carbon/TPU filament, morphology, and X-ray diffraction analysis confirmed GR-TPU exhibited cry… Show more
