Abstract
A disposable sensoring absorbent structure for detecting wetness comprises at least one absorbent layer and at least one sensing device comprising a magnetoelastic film. Such an absorbent structure enables the monitoring the status, e.g., wetness and/or at least one biological and/or chemical analyte, in an absorbent article. A change in status, such as wetness, may reflect an event, such as urination or a feces event. Also included are methods for detecting wetness and/or at least one biological and/or at least one chemical analyte, using the sensoring absorbent structure according to an embodiment of the invention.

- 24. A wetness sensing device for detecting wetness, wherein said wetness sensing device comprises a magnetoelastic film, and said film being coated with a material that interacts with said wetness, resulting in a change in magnetoacoustic oscillations such that a first magnetoacoustic resonant frequency at said sensing device evoked when said sensing device is not influenced by wetness is different from a second magnetoacoustic frequency evoked when said sensing device is influenced with wetness.
