Abstract

• Comparative evaluation of 3D-printed TPU/CB strain sensors fabricated from two commercial conductive filaments (RECREUS and FILI). • RECREUS sensors show higher ductility and negative piezoresistive response; FILI sensors exhibit positive, highly linear behavior at low strain. • TPU/CB/Ag FILI sensors demonstrate minimal baseline drift (
