Electromechanical behavior of the graphene-on-PDMS strain sensors.
(a) The changes in current and resistance (inset) under different strain. (b) Current response at different static strain. (c) Current response at different frequency under 5% strain. (d) Current and relative changes in resistance (inset) of graphene film. All samples were tested under a bias of 1 V.
