From May 18 to 22, 2025, the city of Nice, France, hosted the Tenth International Conference on Advances in Sensors, Actuators, Metering and Sensing (ALLSENSORS 2025) — a key event for professionals and researchers working on cutting-edge sensing technologies.
As part of the scientific programme, the INFINITE project was represented through the publication of two research papers, highlighting ongoing developments in wireless sensing solutions using magnetic microwires:
- Free Space Microwave Stress Sensing in Composites with Ferromagnetic Microwire Inclusions. This study presents experimental results showing how microwave signals in the 2–4 GHz range can be affected by mechanical stress in composites that include ferromagnetic microwires. The observed changes in signal response (S12 parameter) and hysteresis behaviour under stress indicate a strong potential for contactless stress monitoring in both civil infrastructure and aerospace applications.
- Development of Magnetic Microwires with High Magneto-Impedance Effect. The second paper focuses on enhancing the Giant Magneto-Impedance (GMI) effect in Co-rich glass-coated microwires — a core technology for developing high-sensitivity magnetic sensors. The team studied microwires of two different diameters and found significant differences in frequency response, with a GMI ratio of up to 625% achieved in thinner samples at 300 MHz.
These contributions underscore INFINITE’s commitment to advancing next-generation sensing technologies that support real-time structural health monitoring and a digitalised, circular aircraft lifecycle. Events like ALLSENSORS 2025 offer an essential platform to disseminate our work and foster new collaborations within the sensor innovation ecosystem.
