Irreversible luminescent thermal indicator of critical temperature

The researchers are developing an irreversible luminescent thermal indicator of the critical temperature. The device is based on a multilayer module consisting of a porous material with a solvent, a barrier - a membrane and a perovskite film.

The device is an elastic temperature tag with a barrier layer that can be used to activate the device. The device is suitable for transporting products and substances with low-temperature storage conditions, such as vaccines or plants. The label can be presented in the form of a vaccine sticker with the function of an irreversible thermal indicator of the critical temperature, which changes color when the required temperature is exceeded for longer than a critical time and excludes the possibility of falsification of data on storage conditions.
