Fiber optic sensor carpet for lining monitoring

Important results from the project

The project has brought the sensor technology closer to market through input from the project partners, through an improved design that has been developed, and thanks to the new insights from the experiments at Sandvik. It has contributed to the objectives of the program through the involvement of different actors in the value chain with very different operations. The project has also to some extent reinforced fiber optic measurement technology as an area of excellence through the application of fiber optics in practically challenging applications.

Expected long term effects

The outcome of the project consists of : an improved sensor design, a plan of activities for the development of the sensor into a product , new insights as a result of field measurements , as well as suggestions for new applications. The impact is expected to be an increased development rate of the sensor concept. In a longer perspective we envision a product that is valuable for the end-users as well as for other commercial players.

Approach and implementation

The project was a collaboration between Acreo who coordinated and conducted the experiments together with Sandvik , the Swedish School of Textiles who contributed with their expertise on fiber embroidery and who also came with new ideas for applications , Nike Tech who manufactured the sensor mat , ABB who contributed with its expertise in sensors for the steel industry, and Sandvik, who as end user, helped with requirements definition and who enabled, and together with Acreo, conducted experiments in one of their ovens.
