  • Abstract
  • This talk will begin with the underlying working principle of MPTs (Magnetostrictive Patch Transducers), which is the coupling phenomenon between magnetic field and mechanical strain. Then, recent progresses made in magnetostrictive patch transducers will be presented. These include MPT’s for omni-directional Lamb and shear-horizontal (SH) guided wave transduction.

    We also discuss how to generate only the non-dispersive shear-horizontal wave in a pipe in a frequency above the cutoff frequency and present some applications of the developed MPTs for damage characterization. Also, the applications of MPTS for the low-frequency online torsional vibration measurement of propeller shafts in large ships. Recent applications of MPTs for metamaterial applications will be briefly discussed.
