ABSTRACT:
An acceleration sensor essentially consists of a cantilevered laterally bending beam arranged in a housing. Because of its mass inertia the bending beam is deflectable relative to the sensor housing in the plane of the acceleration to be measured. The bending beam has the design of a thin resilient strip which is wide relative to its thickness and is made of amorphous metal. The bending beam may have a one-layer or a multi-layer structure. In case of a multi-layer structure, the friction between the individual strips, causes the vibration to be damped. A small air gap between the walls of a closed housing and the bending beam additionally brings about an air damping of the bending beam's vibrations.
