Pattern-changing textile

Chromosonic is a programmable electronic, color- and pattern-changing textile interface. The heat-responsive textile’s coloration changes dynamically in reaction to processed sound files, which are converted into heat energy, as well as direct contact with the warmth of users’ hands.

Designers Judit Eszter Kárpáti and Esteban de la Torre created the interface using linen that is screen-printed with thermochromic dye. An Arduino open-source platform with a 12 V power supply and twenty custom printed circuit boards drive four industrial 24 V DC power supplies. These supplies heat nichrome wires, which are woven into the fabric, transforming the colors of the thermochromic dyes.

Chromosonic investigates how the world of digital media becomes tangible through a textile. The slow-changing fabric responds to ambient environmental impulses and direct user interaction, demonstrating that digital interfaces need not be exclusively defined by backlit glass planes.
