Abstract
A sensor is configured to detect a tensile, compressive and/or bending forces acting on a carrier (1, 1′) of the sensor. The carrier (1,1′) has at least one planar magnetizable surface (2). The sensor (13) comprises at least two sensor coils (12, 15) which are arranged at a predetermined angle to a longitudinal axis (14) of the carrier (1, 1′). The sensor (13) may be positioned on either side of the carrier (1, 1′). The sensor (13) is capable of detecting changes of the magnetisation due to tensile, compressive and/or bending forces acting on the carrier (1, 1′).
