Magnetoelectric current sensor
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 ...
