A team of engineers has created the most functional flexible transistor in the world — and with it, a fast, simple and inexpensive fabrication process that’s easily scalable to the commercial level. It’s an advance that could open the door to an increasingly interconnected world, enabling manufacturers to add ‘smart,’ wireless capabilities to any number of large or small products or objects — like wearable sensors and computers for people and animals — that curve, bend, stretch and move.
