Abstract

A liquid and/or moisture detecting RFID tag arrangement (1) comprises a substrate (4, 4'), at least one antenna element (2) arranged on the substrate, and an RFID chip (3) connected to the antenna element(s). At least a part of the substrate forms a water degradable part (4), made of a water degradable material, arranged to dissolve or disintegrate when wetted by a liquid. When the water degradable part disintegrates or dissolves, the response signal from the RFID tag arrangement (1 ) changes, either to cease, or to be of different content or characteristics. The change in response signal can e.g. be accomplished by a main antenna (2) becoming totally or partly inoperative, by a secondary antenna (5) becoming fully or partly inoperative, or by breaking a detection loop (5').
