Abstract: This paper reviews graphene's potential as a material for making different types of sensors. Graphene is a monolayer of carbon atoms that exhibits some remarkable electronic and mechanical properties and many of these properties are suitable for applications with sensors. The review attempts to be comprehensive with mass and strain sensors in sensor types covering chemical and electrochemical sensors, magnetic and electrical field sensors, and optical sensors as well. An indication of its versatility and importance is the fact that grapheme offers some advantages over this whole range of sensing modalities. Graphene has emerged as one of the strongest post-silicon technological candidates. One of graphene's most important applications in the foreseeable future is the sensing of particles of gas molecules, biomolecules or various chemicals or the sensing of particle radiation, such as alpha, gamma or cosmic particles. Several unique graphene properties, such as its extremely small thickness, very low mass, large surface-to-volume ratio, very high absorption coefficient, high load carrier mobility, high mechanical strength and high Young's modulus make it exceptionally suitable for sensor making.
