Fig. 14: Suspended graphene with an attached mass.

a A schematic of a few-layer graphene cantilever with diamond-like carbon weights²⁷⁰. b A schematic of a kirigami pyramid made of suspended graphene supporting gold masses and an SEM image of the as-fabricated graphene kirigami pyramid²⁷¹. c An SEM image of a graphene membrane supporting an SU-8 mass²⁷². d Doubly clamped graphene ribbons with an attached silicon-proof mass as the transducer of the NEMS accelerometers¹³⁵. e Fully clamped graphene membranes with attached silicon-proof mass as the transducer of NEMS accelerometers¹⁸³.
