Magnetoelectric current sensor

Y. Zhou,  and S. Priya     Virginia Tech, Blacksburg, VA, USA

Abstract

Magnetoelectric (ME) composites can directly generate an electric signal in response to the applied external magnetic field, leading to a passive sensing without the need of external power sources. In addition, by optimizing the composite material composition and configuration, one can realize significantly large voltage and sensitivity over a wide range of frequency. These considerations are driving the development of ME composites for passive sensing devices, especially on the current/magnetic field sensing. In this chapter, we will systematically describe the development of magnetoelectric current sensors with respect to challenges of typical ...
