Mechanical stress sensor having a ferromagnetic microwire

摘要

The invention refers to measuring equipment and is a mechanical stress sensor. The sensor has a rectangular plate of a polymer material the top surface of said rectangular plate having a cavity where a detector is located. Inside the rectangular plate there is a preliminary tensile amorphous ferromagnetic microwire located inside a measuring coil. The microwire is connected to a first pair of contact pads, while the differential measuring coil is connected to a second pair of contact pads. Both pairs of contact pads are connected to the detector. The detector has an output which is connected to an analog to digital converter coupled with a personal computer.
