The interconnections are able to guide light signals when stretched by up to 30 percent, or when bent around an object with a diameter as small as that of a human finger
One of the flexible, stretchable optical interconnections
If flexible electronic devices are ever going to become practical for real-world use, the circuitry incorporated into them will have to be tough and resilient. We're already seeing progress in that direction, including electrical wires that can still carry a current while being stretched. However, what if the application calls for the use of fiber optics? Well, scientists from Belgium may have that covered, too. They've created optical circuits utilizing what they believe are the world's first stretchable optical interconnections.
