Smart Thermos Flask

University of Lapland developed a prototype thermos flask with integrated electrochromic display, to indicate if the flask contents are hot or cold. The display, temperature sensor, driver electronics and a coin cell battery are integrated into the cap of the flask. The prototype explores the use of a combined red-blue display, leveraging the red ink developed in WP1&2. The display was manufactured by Ynvisible based on the design made by
University of Lapland.
