Abstract

Highly sensitive, wirelessly powered, and maintenance-free sensors are of great interest to the biomedical, geological, hazardous environment, and traffic control communities. This work demonstrates the passively-powered wireless operation of a magnetoflexoelastic magnetometer. The wireless coupling is achieved using a coupled near-field resonant loop antennas, which excite the high Q-factor (∼6000) micromachined quartz resonator. Magnetostrictive curves are acquired both wired and wirelessly at distances up to 45 mm to confirm the phenomenon is magnetoflexoelastic in nature. A 49.1 Hz/Oe sensitivity was achieved in wireless operation and the ultimate detectable limit was 7 μΤ at 0.5 Hz.
