N2 - Advanced sensor network in aircraft can enable in-situ structural health monitoring, reduce unscheduled groundings, and consequently decrease maintenance expenses. This research aims to fabricate lightweight, flexible, wireless, and passive thin film sensors consisting of magnetostrictive thin films, a sensing coil, and yttria-stabilized zirconia substrates. External stress variation changes the magnetic permeability of the magnetostrictive thin films, resulting in an electrical impedance shift on the sensing coil, and thus can be detected wirelessly using a secondary excitation coil. Specifics for the additive manufacturing procedures, experimental data characterized, and theoretical numerical simulations for the magnetostrictive thin film sensors are presented.
