Smart, active and intelligent labeling
This article aims to provide a brief overview of some of these emerging technologies. SMART COATINGS The use of high-performance coatings can enable surfaces to be more responsive to their environment and add functionality. Smart coatings frequently rely on a visible color response to indicate a temperature change or respond to other stimuli, such as a pH change, oxidation, corrosion or electric current. Applications for smart coatings include tamper evidence, time/temperature indicators, anti-counterfeiting solutions, anti-microbial properties, barrier performance and freshness indicators. ...
