Patent abstract
An exemplary magnetic flux sensor in accordance with the present invention is characterized by an electrical output that is proportional to the total static and dynamic flux passing normally through a large area. An oscillating electrical current passing down a conducting area produces Lorentz forces, which are transferred to piezoelectric areas. The piezoelectric areas produce electrical voltage at the oscillation frequency whereby amplitude is proportional to the total magnetic flux passing normally through the conducting area. Demodulating the voltage provides an electrical signal with high sensitivity, dynamic range, and noise immunity.
