It is well recognized that the miniaturization of electromechanical deviceswill bring a revolution to humanity in the coming decades synonymous with theeffects of miniaturizing electronic devices in those previous. Anelectromechanical actuator - a device that converts electrical energy tomechanical deformation or motion - is the core component of many such devices.Consequently, research interrogating mili-, micro-, and nano-actuation has, andwill continue to become increasingly essential. The challenge is that behaviourof actuators at small size scales vastly differs to those at the macroscale. Wecannot simply shrink the size of conventional actuators at the macroscale downto the micro/nanoscale. In addition, conventional actuation materials (such aspiezoelectric ceramics and shape memory alloys) have poor properties andperformances when fabricated at a small length scale. There is an urgent needto discover novel actuation materials at small length scale. This paper willreview recent advances in graphene-based actuation materials. We will focus ondifferent actuation physical mechanisms of this most well-known two-dimensionmaterial. The in-depth physical understanding and insights will lay the groundfor further optimization/development of graphene-based actuators. They may alsoprovide valuable knowledge for the design and development of othertwo-dimensional actuation materials and actuators.
