Abstract
A magnetoelastic resonator device comprises a housing, at least one elliptically-shaped or substantially elliptically-shaped magnetoelastic element disposed within the housing, and at least one bias magnet disposed in the housing, wherein the at least one elliptically-shaped or substantially elliptically-shaped magnetoelastic element is configured to couple to an external magnetic field at a particular frequency and convert the magnetic energy into mechanical energy, in the form of oscillations.
