RVmagnetics Demonstrated Microwire Sensor Performance at the National Physical Laboratory in London

Sensors demonstrated their functionality under cryogenic conditions, including liquid helium and liquid nitrogen, and during exposure to neutron and gamma radiation tested in NPL UK for harsh environments, including defence and space applications.

A team from RVmagnetics completed a series of advanced performance TEVV tests at the National Physical Laboratory (NPL) in London, marking another major milestone in broadening the application area of the company’s unique Microwire sensing technology for extreme environments.

RVmagnetics’ Microwire sensors, embedded in glass fibre and carbon fibre composite samples, were subjected to liquid helium and liquid nitrogen environments, as well as exposure to neutron and gamma radiation. The results demonstrated stable and reliable sensor functionality across all conditions confirming the robustness, resilience, and adaptability of RVmagnetics’ technology for use in harsh environments, including defence and space applications.

“We are proud that our Microwire sensors, embedded in glass fibre and carbon fibre composite samples, have successfully demonstrated their functionality under cryogenic conditions, including liquid helium and liquid nitrogen, and during exposure to neutron and gamma radiation,”

The National Physical Laboratory (NPL) is the United Kingdom’s national metrology institute and one of the world’s leading centres of excellence in measurement science. With over a century of expertise, NPL supports cutting-edge research across sectors including aerospace, defence, energy, healthcare, and quantum technologies. The laboratory provides independent verification, testing, and validation that underpin innovation and ensure confidence in new scientific and engineering solutions worldwide.

This testing was conducted under the NATO DIANA program, which supports Test, Evaluation, Validation, and Verification (TEVV) of dual-use technologies.

The successful NPL campaign represents a significant step toward de-risking and confirming RVmagnetics’ sensing technology for defence, aerospace, and advanced industrial applications.
