MIT Researchers 3D Print Goldbug-Inspired Device

A group of MIT researchers was inspired by the color-changing golden tortoise beetle, or goldbug, when they decided to 3D print an electronic device to demonstrate the feasibility of flexible, 3D printable electronics that react to their environments. The device was printed on the MIT-created mulitmaterial MultiFab 3D printer, which can print up to 10 different materials in one build, and consists of a base made from a rigid plastic and a crossbar printed from a flexible plastic with a strip of silver running along its length. The base includes two 3D printed transistors and a "pixel," or a semi-conductive polymer circle that changes color when the crossbars are stretched, modifying the electrical resistance of the silver strip.
