A team of US engineers has created the world’s fastest stretchable, wearable integrated circuits — a technological feat that can revolutionise the Internet of Things (IoT) and high-speed wireless world in the future.Led by Zhenqiang “Jack” Ma from University of Wisconsin-Madison, the team developed the new stretchable integrated circuits taking inspiration from twisted-pair telephone cables. 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 3-D puzzle — gives the transmission lines the ability to stretch without affecting their performance, said the study, published recently in the journal Advanced Functional Materials.
Researchers in the Netherlands have developed a tiny wireless temperature sensor powered by radio waves. The technology, still in its infancy, could one day power smart homes.The sensor can detect temperature, but could be designed to sense a range of external variables. For example, sensors employed in smart homes could detect the presence of a person in the room and automatically switch on or off air condition and heat.
