Based on graphene oxide and multi-walled carbon nanotube layers, a novel bi-layer actuator that can be remotely controlled with an electromagnetic induction system was developed. The bi-layer actuator showed a large one-way bending deformation under the eddy current stimuli due to the asymmetrical responses originated from the relative differences of temperature of two different carbon layers. For the validation of one-way bending actuation, the coefficients of thermal expansion of carbon nanotube and graphene oxide was mathematically formulated first in this study based on the atomic bonding energy related to the bonding length. The newly designed graphene-based bi-layer actuator that is very sensitive to electromagnetic wave radiation is triggering a new way for the remotely controllable actuator and the potential applications in the various wireless systems.
