RVmagnetics Demonstrated Microwire Sensor Performance at the National Physical Laboratory in London
London, October 2025 – A team from RVmagnetics has successfully 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.
The three-member team — Pavol Lipovský, David Fülöp, and Samuel Nalevanko — collaborated closely with Radka Veltcheva, Karen Alston, Rodrigo da Silva, Graeme Taylor, and Michael Homer from NPL to carry out comprehensive experiments focused on cryogenic and radiation conditions.
Testing at the Edge of Extremes
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 delighted to have had the opportunity to test our Microwire sensors at such a prestigious institution as the National Physical Laboratory (NPL) in London. 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,”
