Optimization analysis of a magnetic-piezoelectric current sensor

Abstract

In this paper, we reported an optimizing analysis for a magnetic-piezoelectric current sensor. The optimizing approach is conducted by investigating the magnetic force interaction between the sensor and the wire by changing the magnetization direction of the magnet and the relative orientations. Furthermore, we established a magnetic bending-moment based analysis and derive the governing equation to quantitatively correlate the magnetic force interaction to the mechanical bending moments. The analysis results show that the modelled results are highly consistent with the experimental results.
