Device for detecting angular accelerations toward rotation degree of freedom and for applying rotational torques or rotational angles toward rotation degree of freedom, has transducer attached to surface of strip material

摘要

The device has a spiral spring (1) arranged in a main extension plane around a normal axis, where a strip material (2) is wound along the main extension plane. The strip material has a fixed end (7) fixed at a base and a free end (6) engaged at a device part in relation to the base. A mechanical electrical transducer (4) is attached to one of surfaces (3) of the strip material in a main extending direction parallel to the normal axis.
