Abstract: A resonator includes a piezoelectric plate and interdigitated electrode(s). The interdigitated electrode includes a plurality of conductive strips disposed over a top surface of the piezoelectric plate. A two-dimensional mode of mechanical vibration is excited in a cross sectional plane of the piezoelectric plate in response to an alternating voltage applied through the interdigitated electrode. The two-dimensional mode of mechanical vibration is a cross-sectional Lamé mode resonance (CLMR) or a degenerate cross-sectional Lamé mode resonance (dCLMR).

Abstract: This disclosure provides systems, methods, and apparatus for detecting magnetic fields. A magnetic sensor can include a substantially planar magnetostrictive layer. A piezoelectric layer can be bonded to a lower surface of the magnetostrictive layer. An electrode layer can be bonded to a lower surface of the piezoelectric layer. The device can be configured such that, when exposed to a magnetic field, at least one of an admittance amplitude, a quality factor, and a resonant frequency of the device is altered. The device can have a resonant frequency in the range of about 1 MHz to about 100 GHz.
