In this work a magnetoelectric (ME) current sensor design based on a
magnetoelectric effect is presented and discussed. The resonant and non-resonant
type of ME current sensors are considered. Theoretical calculations of the ME
current sensors by the equivalent circuit method were conducted. The application
of different sensors using the new effects, for example, the ME effect, is made
possible with the development of new ME composites. A large number of studies
conducted in the field of new composites, allowed us to obtain a high
magnetostrictive-piezoelectric laminate sensitivity. An optimal ME structure
composition was matched. The characterization of a non-resonant current sensor
showed that in the operation range to 5 A, the sensor had a sensitivity of 0.34
V/A, non-linearity less than 1% and for a resonant current sensor in the same
operation range, the sensitivity was of 0.53 V/A, non-linearity less than 0.5%.
