Highly Isotropic Terfenol-D/PZT Magnetoelectric Sensor Based on Nested Ring Structure

In this paper, we studied a highly isotropic sensor for scalar magnetic field measurements and developed a Terfenol-D/PZT composite magnetoelectric sensor based on a nested ring structure. The effect of applied magnetic field, direction, and bias magnetic field on the output characteristics of the structure was studied, and it was observed that it has good linearity and a wide measurement range.
