A piezoresistive flexible strain sensor was developed using thermoplastic polyurethane elastomers (TPU) as the matrix and carbon nanotubes (CNTs) conductive fillers. Sensitivity, range, tensile cycling stability were concurrently considered during its design. Electrospun TPU fiber membranes prepared via electrospinning in this experiment, with controllable diameter achieved by adjusting rotational speed of receiving drum. CNTs incorporated into a polymer substrate through suction filtration to create sensor. The support structure electrospun film served carrier for uniformly adhering particles. Well-dispersed could more easily achieve uniform loading pore size film, thereby forming layer. This study initially determined influence content spinning solution on morphology membrane. Subsequently, effects CNT drum microstructure investigated, along their impact microstructure, mechanical properties, sensing performance CNTs/TPU (CT) sensors. results indicate that membrane under conditions mass fraction 20 wt% 100 r/min has larger average stable scaffold structure. sensor, filtering 10 mL concentration 2 mg/mL, exhibited best strength elongation at break 6.22 MPa 575%, respectively.
