Abstract:
The present invention is generally in the field of measuring and indicating techniques and relates to a time-temperature indicator and methods of manufacturing and use thereof. More specifically, the time-temperature indicator comprises at least one metal layer or metal containing layer, and in direct contact to the metal layer or to the metal containing layer at least one pad member affixed onto a pad carrier layer,wherein the pad member comprises a pad made of an absorbent material and a dopant medium, whereby the dopant medium comprises a liquid medium or a viscous medium or a viscoelastic medium which is doped with a dopant that destroys the metal/metal containing layers such as an acid, a base or a salt or a photolatent acid or a photolatent base.
