This chapter elucidates on some of the work done by different researchers on sensors developed from Carbon Nanotubes (CNTs) and graphene. Work done on the preparation and properties of CNTs and graphene are explained in addition to their employment as electrochemical, strain and electrical sensors. It also explains the work done on a range of wearable, flexible sensors, some of the network protocols used to operate them, the current challenges availing in the present scenario and some of the future opportunities in terms of market survey and betterment of the existing sensors.
