This is my archiveLondon bridge won’t fall! – Nerve-Sensors at GEO Business 2023
We had the opportunity to present Nerve-Sensors at GEO Business 2023. Many thanks to Katarzyna who, as usual, had her hands full talking about our proven field projects in road and rail embankments, collectors, pipelines and many other geotechnical structures.
Thanks to all the Participants and Organisers for a great job;)Finding new talent at the International Photonics Job Fair in Warsaw
DFOS-based structural health monitoring and the corresponding R&D require the expertise of specialists in construction, geotechnics, mechanics, electronics, computer science, optics, and photonics.
That is why we were at the International Photonics Job Fair at the faculty of physics of the Warsaw University of Technology to recruit talented individuals and future experts in the field of optical sensors!
Special thanks to Łukasz, Tymoteusz and Tomasz for representing Nerve-Sensors at the fair! 💪Nerve-Sensors at a conference in Taiwan
Smart City Summit & Expo is the largest hybrid smart city tradeshow featuring IoT solutions. We have spent three days participating in great meetings, networking sessions and forums and can’t wait to visit this beautiful country again. We shared a stand on the 4th floor of the Global Pavilion with the Polish Technological Platform on Photonics.Happy Holidays from the Nerve-Sensors team!
This 2022 has gone very quickly, and it’s time for the last thank you post to the whole team, with whom we have completed a lot of unique projects. But most of all, we would like to thank all our clients and friends for giving us constant motivation, feedback, and, in the end, satisfaction with the achieved challenges.
Something ends, and something begins. We enter the New Year with even more passion for satisfying our engineering hunger. During the upcoming Christmas time, we wish you all the peace, health, and rest with your loved ones, and after the New Year, come back to work with even more enthusiasm and joy!
Thank you – Nerve-Sensors team!Winter DFOS measurements of the railway line
It’s finally a beautiful, real Polish winter!⛄️
And we start with DFOS measurements of the railway line at -15°C:
❄️ more than 2,200 m of sensing path
❄️ three scatterings: Rayleigh, Brillouin, and Raman
❄️ five independent optical devices
❄️ short-term load tests and long-term monitoring
❄️ static and dynamic readings
❄️ strains, stress, temperatures, curvatures, and displacements
❄️ DFOS supported by automatic inclinometer system
This is the first such project in Poland!An Introduction to High-Definition Fiber Optic Sensing
We encourage you to watch the exciting and informative webinar hosted by David Potter from Luna Innovations. Principles of distributed sensing approach are discussed, and many practical examples are presented, including civil engineering applications with Nerve-Sensors! 💪

“An Introduction to High-Definition Fiber Optic Sensing”
With the ever-growing demand for intelligent and autonomous systems, fiber optic sensing continues to evolve as a critical tool to acquire the essential measurement data and insights that engineers need. More specifically, high-definition fiber optic sensing (HD-FOS) has emerged to play a critical role in the development, manufacturing, and maintenance of today’s advanced products and technologies across many industries, including aerospace, electric vehicles, energy and civil infrastructure.
As an alternative to traditional test and measurement sensors, such as strain gages, thermocouples and RTDs, HD-FOS delivers a versatile solution to easily measure more critical data without the hassle and limitations of bulky electrical sensors and their associated cabling. And compared to other fiber optic sensing technologies, HD-FOS is the only solution that converts a standard optical fiber into an ultra-fine resolution linear sensor for accurate strain and temperature measurements.
This webinar will describe how fiber optic sensing works and the basics of how HD-FOS is used and applied. We will also review examples of successful HD-FOS applications in several areas, including structural testing with advanced composite materials, thermal monitoring for manufacturing process control, thermal analysis of battery and powertrain systems, and structural health monitoring involving crack and defect detection in concrete and modern composite components.Mediterranean conference marathon behind us
We were really pleased to be the participant in the 10th European Workshop on Structural Health Monitoring in Palermo. We presented a paper „Composite and monolithic DFOS sensors for load tests and long-term structural monitoring of road infrastructure„.
Just after that, we visited beautiful Barcelona to discuss bridge maintenance, safety and management (IABMAS2022) with the use of composite DFOS sensors and DFOS approach. Our paper, ’Distributed fibre optic sensing for safety monitoring of concrete, steel and composite bridges’, summarised the Polish achievements to date in bridge monitoring using DFOS technology and monolithic Nerve-Sensors. We also presented our first projects in Germany and USA.
Thanks to the Organizers and Participants for these great events. We met interesting people and engineers from all over the world, and it was our pleasure to have such informative conversations!
We have already collaborated with almost all technical universities in Poland. Now, the list has been extended by the Lodz University of Technology (Politechnika Łódzka). It is our pleasure to support measurements of reinforced concrete slabs and beams strengthened with shape-memory steel. This unique research is done under the supervision of prof. Renata Kotynia. Congratulations! 👍💪Most outstanding exhibition in Edinburgh!
We are pleased to announce that SHM System & Nerve-Sensors stand was awarded for the most outstanding exhibition at the 18th European Bridge Conference in Edinburgh! Congrats to our team for this great job!
We also presented an article: „Composite DFOS sensors as a nervous system of smart bridges – examples of load tests” during this event.

Distributed strain measurements of prestressed concrete elements with fibre optic sensors – abstract
The article presents the application of the technology of distributed strain measurements to prestressed concrete members. Distributed fibre optic sensing technology is based on light backscattering and enables strain measurements with high spatial resolution over the entire length of the optical fibre. Such an approach allows the replacement of thousands of conventional spot strain gauges, arranged in series, with a single optical fibre. The article presents composite fibre optic sensors and their application for strain measurements and cracks development investigations. Three practical examples of prestressed concrete elements were described, namely truck scale platforms, prestressed concrete girders with a length of 24 meters, and one of the largest bridges in Poland. The structural members were analysed at different stages of construction, during fabrication and hardening, tendon activation, installation, proof loading, and also as a post-installed measurement system. The aim of this article was to demonstrate the possibilities of measurements with composite distributed fibre optic sensors.
