Scientists have found that the internal nonlinear magnetization dynamics of microwires can be used as a sensitive parameter in inductive sensors.
Researchers from IKBFU and NUST MISIS have studied the potential of amorphous and nanocrystalline micro-materials as compact sensor elements for non-contact inductive sensing. This was reported by the TASS to press service of the Russian Ministry of Education and Science.

| For the first time, two non-contact methods of signal reading have been compared: the detection of the switching field of object magnetization in the time domain; harmonic (spectral) analysis of the induced stress in the frequency domain. Both approaches have been shown to be effective in various practical scenarios, |

It is noted that the scientists have presented an analysis of the physical properties of micro-objects and demonstrated their applicability in practical tasks, such as miniature, energy-efficient, and adaptive sensors for monitoring mechanical stress in structures, non-contact temperature measurement in biomedical systems, and the detection of magnetic particles. The authors emphasize the potential of such elements for embedded wireless sensor solutions in engineering and medical applications.
In addition to extensive research on existing solutions in the field of magnetic sensing, the scientists' studies have presented new scientific results, demonstrating that the internal nonlinear magnetization dynamics of micro-wires can be used as a sensitive parameter in inductive sensors.
