초록

Stretchable strain sensors have attracted increasing interest for applications in wearable electronics, human motion monitoring, and soft robotics. To achieve high performance, they must exhibit both high stretchability and sensitivity. In this study, graphene nanosheets were vertically grown on carbon nanofibers using electrospinning followed by thermal chemical vapor deposition. These were combined with two-dimensional reduced graphene oxide to form conductive films. Wrinkling these films enhanced their mechanical compliance, enabling their use as resistive strain sensors. The sensor exhibited a high stretchability of up to 392%, a large gauge factor, and excellent repeatability.
