Abstract
A piezoelectric sensor for bending moment measurements has measuring elements separating at their axes and electrically connecting both halves with their opposing directions of polarization. Such a sensor, mounted with its axis on the neutral bending axis of a machine structure, thus measures concurrently both tension and compression of the machine on both sides of the axis thereof.
