  • Patent number: 8558052
    Abstract: A method for providing a piece of a film of a magnetoelastic material having an initial bending stiffness with an enhanced bending stiffness in a first direction. According to the method, the piece is provided with at least one scored line in the first direction of the piece. Furthermore, the piece is bent along at least one of the at least one scored lines so as to provide the piece with a lasting bend in a direction transverse to the first direction, whereby an enhanced bending stiffness is provided in the first direction of the piece. Also, a product obtained by the method, a sensor and an absorbent structure and an absorbent article including the sensor.
