Abstract

Some aspects of the present disclosure feature a sensing device comprising a magnetic bias layer, a resonator, a spacer, and a housing. The spacer includes an environmental change receptor. The thickness of the environmental change receptor rapidly increases in response to a change to an environment variable.

Description

technical field [0001] The present disclosure relates to magnetomechanical resonator sensors designed to monitor environmental variables, biological variables, and systems using these sensors. Background technique [0002] A magnetomechanical resonator (MMR) is powered using a radio frequency source that produces a magnetic field. MMR sensors are based on the principle of magnetostrictive and magnetoelastic coupling. Magnetostriction involves changing the shape of ferromagnetic materials when subjected to a magnetic field. Magnetoelastic coupling involves the relationship between stress and tension in a material when subjected to a magnetic field. [0003] Typically, MMR sensors are coupled to an external magnetic field and receive magnetic energy from the field. MMR sensors convert magnetic energy into mechanical oscillations. When the magnetic field is removed, the mechanical oscillations are converted into magnetic energy, and the sensor radiates the magnetic field at...
