Abstract :
The paper shows the gravure printing technology is used as deposition method to pattern a graphene film on flexible polyimide substrates for a wireless strain sensor (WSS). According to the inductive coupling between the reader antenna and the graphene pattern (GP), a change in the GP characteristic can be detected wirelessly by a corresponding change in the complex impedance of the reader antenna. The WSS overcomes the inadequacy of the existing conventional sensors limited monitoring locations. And the WSS also exhibits a high sensitivity of 51% under a load of 100 N.
