Piezoelectric Magnetic Field Sensor Based on a Planar Bimorph Structure with Current
Piezoelectric permanent magnetic field sensor using a planar bimorph lead zirconate titanale structure with additional current carrying conductor is described. The sensor operation is based on combination of the Ampere force and the piezoelectric effect. Sensitivity of the sensor was 10 equal to 10 W(A*kOe) and minimal detecting field was 0,1 Oe at the bending resonance frequency of the structure.
