Pressure sensors based on the eddy current effect. The eddy current effect is produced by a moving magnetic field intersecting a metallic conductor or by a moving metallic conductor meeting perpendicular to the magnetic field. In short, it is caused by the electromagnetic induction effect. This action produces a current that circulates in the conductor. The eddy current characteristic makes eddy current detection have characteristics such as zero frequency response, so eddy current pressure sensors can be used for static force detection.
