Eleventh Order Lamb Wave Mode Biconvex Piezoelectric Lorentz Force Magnetometer for Scaling Up Responsivity and Bandwidth

摘要

We report the novel use of a higher harmonic Lamb wave modes to realize a piezoelectric readout Lorentz force magnetometer (LFM). The proposed design aims to significantly enhance the pre-amplified sensitivity per unit of excitation current (referred to as the responsivity here) relative to the fundamental mode in the same resonator. By exploiting an 11
