Abstract:
Some aspects of the present disclosure feature a sensing device comprising a magnetic bias layer, a resonator, a spacer, and an environmental change receptor. The environmental change receptor is disposed on a surface of the resonator. The mass of the environmental change receptor is changed in response to a change in environment. The resonant frequency of the sensing device shifts in response to the mass change of the environmental change receptor.
