Abstract
High sensitivity and flexible Graphene Hall elements (GHEs) were demonstrated. The average and maximum current-related sensitivity of our GHEs are respectively 2030 V/AT and 2364 V/AT, outperforming almost all reported Hall sensors. In addition, the GHEs fabricated on flexible substrate show high sensitivity, linearity and stability against bending. Our work shows that graphene Hall sensors are promising in accurate detection of magnetic field and flexible sensing systems.
