Turkey-Inspired Sensor Schematic (image) University of California - Berkeley Caption Bio-inspired sensors are made from bacteriophages that mimic the collagen fibers in turkey skin. When exposed to target chemicals, the collagen-like bundles expand or contract, generating different colors. The researchers also created a mobile app to be used with camera phones to help analyze the sensor's color bands.
