Abstract: Graphene nanoribbons provide an opportunity to integrate phase-coherenttransport phenomena with nanoelectromechanical systems NEMS. Due to thestrain induced by a deflection in a graphene nanoribbon resonator, coherentelectron transport and mechanical deformations couple. As the electrons ingraphene have a Fermi wavelength \lambda ~ a 0 = 1.4 {\AA}, this coupling canbe used for sensitive displacement detection in both armchair and zigzaggraphene nanoribbon NEMS. Here it is shown that for ordered as well asdisordered ribbon systems of length L, a strain \epsilon ~ w-L^2 due to adeflection w leads to a relative change in conductance \delta G-G ~ w^2-a 0L.
