▎ 摘　　要

Strain Sensors have rapidly pervasived in modern era due to their ability to identify, respond and exchange mechanical motion into an electrical signal that can be interpreted on the basis of electrical resistance. As a matter of fact, strain sensors applications have expanded the technology scope and enabled us to observe the changes in the surroundings in distinct ways. More recently, advanced carbon nanomaterials-based films for sensing application have been extensively growing because of their outstanding properties. Based on nanomaterials distinctive structure, enhanced material strength can be obtained in addition to the added multifunctionality of these materials. Such remarkable feature is a main factor in the design of sensors composed of functional nanomaterial. At present carbon nanomaterials, particularly graphene is promising choice for the sensor development due to its unique thermal, electrical and mechanical strength. Therefore, this paper critically discussed on brief history, graphene synthesis, properties, structure, derivatives, graphene based nanocomposites and strain sensor application of graphene based nanomaterials.
