Scientists have created the world’s fastest, stretchable, wearable integrated circuits, an advance that could drive the Internet of Things (IoT) and lead to a much more connected, high-speed wireless planet.The platform, developed by the University of Wisconsin-Madison engineers may help manufacturers expand the capabilities and applications of wearable electronics–including those with biomedical applications – particularly as they strive to develop devices that take advantage of next-gen wireless broadband technologies like 5G.
Microwave radio frequencies are electromagnetic waves that use frequencies in the 0.3 gigahertz (GHz) and 300 GHz range, which fall directly in the 5G range. In mobile communications, the wide microwave radio frequencies of 5G networks will accommodate a growing number of connected devices and notable increases in data speeds and coverage areas.
In an intensive care unit, epidermal electronic systems (electronics that adhere to the skin like temporary tattoos) could allow healthcare staff to monitor patients remotely and wirelessly, increasing patient comfort by decreasing the customary tangle of cables and wires. What makes the new stretchable integrated circuits so powerful is their unique structure, inspired by twisted-pair telephone cables, researchers said. They contain, essentially, two ultra-tiny intertwining power transmission lines in repeating S-curves.
This serpentine shape, formed in two layers with segmented metal blocks like a three-dimensional puzzle, gives the transmission lines the ability to stretch without affecting their performance. It also helps shield the lines from outside interference and, at the same time, confine the electromagnetic waves flowing through them, almost completely eliminating current loss.
