In this presentation, the concept, theory, and application of ‘lab-on-sensors’ are briefly introduced. The ‘lab-on-sensors’ concept is detailed in its application to corrosion sensors. Then, the recent development of metal-coated corrosion sensors based on long period fiber gratings (LPFG) is reviewed in three forms of metal coatings: (1) nano iron particles mixed with epoxy, (2) Fe-C mixture applied over a silver layer, and (3) Fe-C mixture applied over a graphene layer. Such a corrosion sensor is used to monitor the change in wavelength as the metal coating is corroded gradually. The wavelength change is calibrated with the degree of corrosion in metal coating. When the corrosion sensor is deployed next to a steel member, the measurement of wavelength change from the corrosion sensor enables the prediction of steel member corrosion from the calibration curve and the wavelength measurement.
