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 a time temperature indicator comprising 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 doped polymer layer, wherein the dopant is an acid, a base or a salt or a photolatent acid or a photolatent base which dopant is added to the polymer, and/or at least one polymer layer wherein a polymer is functionalized with acidic or latent acidic or basic or latent basic groups; or a time temperature indicator comprising at least one polymer layer containing metal particles and a photolatent acid or a photolatent base, or at least one polymer layer containing metal particles wherein the polymer is functionalized with latent acidic or latent basic groups.

A device for activating and dispensing a two-label system in which the system becomes activated upon contact of a first label with a second label, the device comprising a first dispenser carrying the first label and a second dispenser carrying the second label, said first and second dispensers being disposed such that said first dispenser dispenses the first label and said second dispenser dispenses the second label, such that the two labels become attached to one another to thereby activate the two label system, and the attached activated layers are thereby provided.
A device for activating and dispensing a photolatent label, comprising a label dispenser for dispensing and attaching said label onto the surface to which it is to be attached, and a light source for illuminating and thus activating the photolatent label as it is being dispensed.
A time temperature indicator comprising at least one metal layer or metal containing layer and in contact to the metal layer or to the metal containing layer at least one doped polymer layer, wherein said at least one doped polymer layer is an adhesive and wherein said at least one doped polymer layer etches the metal layer or the metal containing layer, wherein an extent of etching of the metal layer or to the metal containing layer indicates elapsed time and temperature, wherein the dopant comprises phosphoric acid, which dopant is added to the polymer, and further comprising two label dispensers where one dispenser attaches the label bearing the doped polymer layer to the surface of the metal layer while the second dispenser deposits the combined labels atop the surface of the good to which the TTI indicator is to be attached.
