The Climate Dress can signal how much CO2 is in the air. The dress has over a hundred tiny LED lights inserted into the embroidey, a CO2 sensor and an Arduino Lilypad microprocessor. The LEDs visualize the level of CO2 in the nearby surroundings and are powered trough the embroidery. The dress senses the CO2 concentration in the air, then accordingly creates light patterns varying from slow, regular light pulsations to short and hectic. The technology is a collaboration between Copenhagen based design studio diffus, Swiss embroidery company Forster-Rohner, the Danish research-based limited company Alexandra Institute and the Danish School of Design.
