Jordan Geiger developed Litmuscreen as an architectural and product design material based on the performance and properties of litmus paper. Litmuscreen is a simple modification to an old technology—the adaptation of chemical properties found in lichen to indicate acid/base imbalances in a liquid. In this product’s application, a rugged textile suitable to exterior uses displays shifts in color to red or blue as an indicator of environmental pollutants in rain. The intuitive interface provides real-time information regarding local air pollution conditions, without the use of electricity or additional construction.
