Graphene-based microelectromechanical systems (MEMS) are very promising candidates for next generation miniaturised, lightweight, and ultra-sensitive devices. In this paper we review the progress to-date of the assessment of the mechanical, electromechanical, thermomechanical properties of graphene towards application in graphene-based MEMS. Graphene possesses a plethora of outstanding properties-such as a 1 TPa Young's modulus, exceptionally high 2D failure strength that stems from its sp 2 hybridization, and strong sigma bonding between carbon atoms. Such exceptional mechanical properties can enable, for example, graphene-based sound sources capable of generating sound beyond the audible range. The recently engineered piezoelectric properties of AFM-tip-pressed graphene membranes or supported graphene on SiO 2 substrates, have paved the way in fabricating graphene-based nanogenerators and actuators.On the other hand, graphene's piezoresistive properties have enabled miniaturized pressure and strain sensors. Two-dimensional graphene nanomechanical resonators can potentially measure
