A Finemet-based microfluidic single-coil microsensor for monitoring oil condition.

Wear is an unavoidable phenomenon that generates debris particles. i.e., ferromagnetic and non-ferromagnetic particles. If the system's condition is not monitored effectively, wear can lead to the breakdown of the system. Therefore, an inductive-resistance sensor was designed to monitor and detect debris particles. Moreover, Finemet (Fe 73.5 Si 13.5 B 9 Nb 3 Cu 1) was applied to the sensor to improve its sensitivity. A comparison simulation and experiment examined the sensor's performance and Finemet's impact. The study shows that the induction mode has greater sensitivity in detecting ferromagnetic particles, while the resistance mode is more sensitive in detecting non-ferromagnetic particles. This study also demonstrates that the application of Finemet boosts the sensitivity of the sensors in both findings, indicating the significance of Finemet for the sensor's applications.
