Abstract
This paper reports a stretchable pressure sensor based on MXene/PVDF composite film for motion detection and tactile recognition. The molecular dynamics model is created to reveal the effects of the MXene sheets on the conformation of the PVDF chains. MXene/PVDF nanofibers are fabricated by electrospinning process, and stretchable serpentine electrodes based on nanosilver paste were obtained by screen printing method. The microfabricated sensor with sufficient stretchability of 8% exhibits high sensitivity with 55.42 mV/kPa, which is improved by 3.5 times compared with pure-PVDF sensor. The finger motion detection and tactile recognition are realized by this sensor due to its high sensitivity.
