主　　题：Pressure sensor Graphene scrolls Hybrid films Electronic skins 

摘      要：In recent years,flexible pressure sensors have attracted much attention owing to their potential applications in motion detection and wearable *** a result,important innovations have been reported in both conductive materials and the underlying substrates,which are the two crucial components of a pressure sensor.1D materials like nanowires are being widely used as the conductive materials in flexible pressure sensors,but such sensors usually exhibit low performances mainly due to the lack of strong interfacial interactions between the substrates and 1D *** this paper,we report the use of graphene/graphene scrolls hybrid multilayers films as the conductive material and a microstructured polydimethylsiloxane substrate using Epipremnum aureum leaf as the template to fabricate highly sensitive pressure *** 2D structure of graphene allows to strongly anchor the scrolls to ensure the improved adhesion between the highly conductive hybrid films and the patterned *** attribute the increased sensitivity(3.5 k Pa^-1),fast response time(50 ms),and the good reproducibility during 1000 loading-unloading cycles of the pressure sensor to the synergistic effect between the 1D scrolls and 2D graphene *** results demonstrate that these sensors are promising for electronic skins and motion detection applications.
