Description

Available for purchase at: https://www.inventables.com/technologies/temperature-sensitive-flexible-sheets This is a thermochromic, ready to use, vinyl material that is coated with liquid crystal and then covered with a clear polyester over laminate. These flexible sheets can be cut to size and used to create a touch sensitive color changing graphic that changes from black through the visible spectrum in between the temperature range of 25ºC to 30ºC (77ºF to 86ºF). The black to red color change occurs at 25ºC, the green color starts at 26ºC, the blue color starts at 30ºC and the clearing point when the film changes back to black is 34ºC. The colors observed depend not only on temperature but also on the viewing angle.
