Our research is concerned with development of inexpensive sensors, with no internal power
supply, that can be used for remote query sensing of environmental and chemical
parameters. 1–3 In response to a time varying alternating-current ac magnetic field thick-film
ribbons of magnetoelastic amorphous ferromagnetic alloys efficiently translate magnetic
energy into elastic energy4, 5 which, in turn, acts to mechanically deform the material. This
mechanical deformation is greatest along the length of the ribbon, and demonstrates a …
