The CHARISMA project has achieved significant milestones in developing cutting-edge technologies for smart labels. These labels incorporate irreversible electrochromic indicators, chemical thermal sensors, and printed flexible supercapacitor energy storage modules, paving the way for advanced applications in various industries.
One key objective was to create irreversible electrochromic indicators with optimal performance for integration into commercial technologies. These indicators needed to meet specific criteria such as activation voltage, coloration efficiency, thermal and environmental stability, contrast, and switching time. By utilizing different monomers and mixtures, the project achieved multichromic indicators with enhanced performance. The most stable indicators demonstrated resilience even after prolonged exposure to high temperatures, ensuring reliable performance in various conditions.
The integration of chemical thermal sensors played a crucial role in the smart label system. These sensors detect temperature variations, triggering responsive actions within the label. The change in conductivity of the sensor serves as a switching mechanism, activating the supercapacitor energy storage module, which powers the electrochromic visual indicator.
A significant achievement was the development of a printed flexible supercapacitor energy storage module. This module, comprising three printed supercapacitors connected in series, offers optimal power storage capacity and flexibility. Utilizing non-toxic materials in fabrication ensures minimal environmental impact, aligning with sustainability goals.
The innovative smart label system holds promise for various applications, particularly in industries requiring stringent temperature control, such as pharmaceuticals and logistics. The ability to monitor temperature deviations in real-time provides invaluable insights into product integrity throughout the supply chain.
The success of the CHARISMA project stems from close collaboration between academia and industry partners. Through multidisciplinary training and collaborative research, the project has fostered innovation and advanced the field of printed electronics. The integration of diverse expertise has led to the development of practical prototypes with significant potential in the market.
The advancements made within the CHARISMA project represent a significant leap forward in smart label technology. By combining scientific rigor with industrial applications, the project has laid the foundation for the future of printed electronics, offering sustainable and versatile solutions for various industries.
