Abstract
A MEMS magnetometer comprises a deflectable resonator comprising a base layer; a Lorentz force (LF) drive conductor attached to the base layer; and a piezoelectric sensor attached to the base layer and electrically isolated from the LF drive conductor. The LF drive conductor comprises conductive material configured for receiving a current at a mechanical resonant frequency of the device capable of causing mechanical deformation of the deflectable resonator, wherein the current causes formation of Lorentz forces in a presence of a magnetic field, and wherein the deflectable resonator is mechanically deformed as a result of the formation of the Lorentz forces. The mechanical deformation of the deflectable resonator generates a detectable piezoelectric electrical signal that is proportional to the magnitude of the magnetic field.
