Abstract:

In order to detect the strain in a specific direction, aligned polyvinylidene fluoride (PVDF) nanofiber mats were fabricated via magnetic electrospinning and packaged in soft materials to prepare flexible and anisotropic strain sensors. The effects of electrospinning parameters on the morphology of nanofibers were studied. Raman spectroscopy was used to characterize the crystal form in PVDF nanofibers. The performances of flexible strain sensors and the feasibility of applying the sensor in monitoring ureteral peristalsis were tested. The experimental results show that PVDF nanofibers fabricated by an 11.5 kV voltage under 10 cm eletrospinning distance and 5 mL/h injection rate present uniform morphology and best alignment. The β phase is in the predominant crystal form in the PVDF nanofiber. Bending test shows that the sensor generates an obvious response signal for the bending perpendicular to the PVDF nanofiber, while the sensor is insensitive for the bending in parallel to the PVDF nanofiber. The work shows that the sensor performs good anisotropic detection sensitivity to strain.

Key words: polyvinylidene fluoride, flexible sensor, electrospinning, anisotropy, nanofiber, detection of ureteral peristalsis
