Magnetoelastic transduction is an inherently wireless technique that does not require any onboard power; thus it offers considerable opportunities in both sensing and actuating microsystem applications. However, the technique is relatively young in its development and solutions to miniaturization and integration challenges are still emerging. This paper details some of these challenges, including...
A dynamic model is presented for a novel magnetoelastic rotary micro-motor. Magnetoelastic excitation results in a rotary motor with comparatively large payload even under direct wireless actuation, but the resulting stator behavior is significantly different from that of prior micro-scale rotary motors. A parametric modal model is developed from conservation of momentum, a second order linear distributed...
