| Description | Two sensor probes for monitoring relative humidity and chloride profiles in building stones were designed, developed and tested for their reliability in practical case studies. They are now commercially available through a University spin-out, Sengenia Limited |
| Exploitation Route | The development of the sensors and the probes was published in both international conferences and journals. Therefore, in addition to academics and other researchers benefitting from the sensor probes, they are now available through Sengenia for use by the industry. |

| Description | FBG based relative humidity probe and refractive index based chloride sensor probes were developed for use in building stones. They were tested in wetting-drying regimes with and without chloride salts. Findings from the work led to protocols for the use of fibre optic sensor probes for monitoring building stones. |
