FIELD: physics.
SUBSTANCE: invention relates to a method of making a piece (2, 4) of a film (1) of magnetoelastic material having initial flexural rigidity when flexural rigidity is increased in the first direction. In accordance with this method, a piece (2, 4) is provided with at least one linear depression (5) in the first direction of the piece (2, 4). Also the piece (2, 4) is curved along at least one linear depression from one or more linear depressions (5) in order to obtain a piece (2, 4) with stable flexure in a direction across the said first direction, through which high flexural rigidity is ensured in the first direction of the piece (2, 4). The invention also discloses an absorbent product made using said method, a sensor, an absorbent structure and an absorbing article having said sensor.
EFFECT: invention enables formation of a piece of film having initial flexural rigidity when flexural rigidity is increased in the first direction.
