Hydrogen leak detection using fiber optics

Hydrogen is becoming increasingly important for clean energy and industry. However, the use of hydrogen also presents safety challenges. This project developed a sensor for monitoring hydrogen leaks over long distances.

Graphene-coated optical fibers for sensor applications

Optical fiber coatings are essential for the performance and reliability of the optical fiber in application. In this project, RISE developed a nanocomposite coating using graphene oxide and polyimide, and validated its potential …

DAS for vibration monitoring and passive seismic exploration of rock

The present project is a feasibility test that focuses on the exploration and characterization of the mining site of Malmberget via an acoustic technique based on optical fibers (Distributed Acoustic Sensing, DAS). It is a unique …

Flexible X-ray detectors (Flex-Ray)

Unlike traditional X-ray film, today's digital detectors are rigid, which means that they can't be used to analyze three-dimensional surfaces. This project developed technology for flexible digital X-ray detectors.

Pressure sensors for machine integration and harsh environments (fiber

Fail-safe machinery is fundamental to industrial competitiveness, and monitoring of equipment condition is crucial. In this project, we developed fiber optic pressure sensors for integration in heavy machinery.

Quantum Technologies

Quantum technology stands on the threshold of a breakthrough that will reshape our entire society. For many organizations in both the public and industry sectors, it's no longer a question of if, but when and how to take the step …

Fiber optic sensors

Fiber optic sensors are insensitive to electromagnetic fields, can be interrogated at a distance, and can withstand harsh environments.

Fiber optics

Want to measure temperature at hundreds of positions in a harsh environment? Do you need to bring intelligence into systems where you can't use electricity? Do you want to develop new solutions for minimally invasive surgery? Then…
