This Engage Plus project will continue a research ended in a previous Engage project and will have significant applications for potential end-users in the energy and mining sectors, in addition to directly benefiting QPS Photronics Inc. The latter is a Canadian high tech company and a world-class leader of Fiber Bragg Grating (FBG) sensor technology and solutions. Under this study is a new technology essential for the safe operation of engineering structures such as the power generators, the mining equipment and the oil and gas pipelines. Typically for down-well and pipeline applications the environment temperatures reach 300°C and above or cycle at -50°C to 125°C extremes. Advanced sensor technologies that can endure harsh working conditions and maintain stable operation for five years are rare but in high demand. Improving the current sensor capacity and reliability will significantly impact the company's R&D and commercialization efforts, helping its business
