      abstract     = {Controlling the Dirac point voltage of graphene is
                      essential for realizing various practical applications of
                      graphene. Here, control of the doping state is achieved in
                      flexible graphene field effect transistors (GFETs) by
                      applying mechanical bending stress. By gradually increasing
                      the bending strain (the decrease of upward/downward bending
                      radius), the Dirac point (VDirac) linearly shifts to
                      left/right, which is induced by the flexoelectric effect of
                      the ferroelectric Pb0.92La0.08Zr0.52Ti0.48O3 (PLZT) gate. In
                      addition, a superior mechanical antifatigue character is
                      obtained in the flexible GFETs, and the doping effect is
                      recoverable. The sensitivity to strain and high bending
                      stability not only offer an easy, controllable and
                      nonintrusive method to obtain a specific doping level in
                      graphene for flexible electric devices, but also highlight
                      the enormous potential of the flexible ferroelectric
                      PLZT-gated GFETs as wearable sensors.},
