Abstract
A sensor for sensing rotational displacements of a body comprises an elongated beam of a material providing a piezoelectric effect. The elongated beam has a first and second ends and a central portion, with the ends of the beam being attached to an interior surface of a case. The case, in turn, is attached to the body. When the body is subject to rotational accelerations, the beam is stressed, and a piezoelectric voltage is generated across the length of the beam.
