The POSPORI project has marked a significant advancement beyond the current state of the art in the field of fibre sensing technology and structural health monitoring. By leveraging innovative technologies and interdisciplinary collaboration, the project has developed novel polymer optical fibre Bragg grating (POFBG) sensors capable of detecting in-situ changes in reinforced structures, such as internal strain, stress, temperature, humidity, and interfacial debonding (bond-slip) between rebars and concrete. The use of a custom-made polymer optical fibre with specific core and overcladding properties has enabled enhanced sensitivity and resilience, setting a new standard in the field. The successful development and testing of novel prototype sensors in intended and operational environments, including soil monitoring and reinforced concrete monitoring in residential structures, have demonstrated the potential of the technology, laying the groundwork for further refinement and potential industrial applications. The project's collaborative nature, involving different teams and disciplinary areas across nations, has facilitated a rich exchange of know-how and expertise, fostering a broader understanding of the technology's potential applications. The innovative prototype sensors developed in the POSPORI project have the potential to contribute to more sustainable urban development, reducing unnecessary expenditures, and enhancing public safety, with clear pathways to potential socio-economic benefits. Beyond the immediate applications in structural health monitoring, the innovations hold promise for other sectors using fibre sensing technology, such as transportation, industrial automation, and healthcare, leading to transformative changes in various domains.
