TANMS nanoscale multiferroic motor proof-of-concept demonstration

The TANMS nanoscale multiferroic motor proof-of-concept demonstration: Top right : Future motor superimposed against a red blood cell for size comparison; middle: magneto-elastic ring on top of a piezoelectric substrate (PMN-PT)*, where the magnetic microbead is trapped by the magnetic force of the magneto-elastic domain structure (when an electric field is applied, the domain rotates and drags the microbead with the domain—a motion similar to that in conventional electromagnetic motors where a magnetic field drives a stator); bottom panel: four pictures represent an experimental demonstration of positioning the magnetic microbead with an applied electric field.
