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.
Claims17
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, the method comprising the steps of:
- a. providing said piece with at least one scored line in said first direction of said piece, and
- b. bending said piece along at least one of said at least one scored line so as to provide said piece with a lasting bend in a direction transverse to said first direction, whereby an enhanced bending stiffness is provided in said first direction of said piece,
- wherein said piece is provided with said at least one scored line by an etching process, said etching process being one of a chemical process, an electrochemical process, an ion beam process or a photo etching process.
A sensor comprising a piece of a film of a magnetoelastic material, which piece has an initial bending stiffness in a first direction, wherein said piece is provided with at least one scored line in said first direction of said piece and that said piece is bent along at least one of said at least one scored line such that said piece is provided with a lasting bend in a direction transverse to said first direction, whereby an enhanced bending stiffness is provided in said first direction of said piece,
- said piece coated with a detection layer on one side, wherein another side is uncoated, the at least one scored line being provided on the side that is not coated.
