It is shown as magnetoelastic sensor may be able to measure point displacement from some centimeters down to 10 -7 m. In some examples of basic applications the good agreement among the theoretical predictions and the experimental results is reported. The proposed sensors are both sensitive as those founded on optical techniques and strength as the mechanical similar devices.
