The consumer marketplace is flooded with a lively assortment of smart wearable electronics that do everything from monitor vital signs, fitness or sun exposure to play music, charge other electronics or even purify the air around you — all wirelessly.
Now, a team of University of Wisconsin—Madison engineers has created the world’s fastest stretchable, wearable integrated circuits, an advance that could drive the Internet of Things and a much more connected, high-speed wireless world.
Led by Zhenqiang “Jack” Ma, the Lynn H. Matthias Professor in Engineering and Vilas Distinguished Achievement Professor in electrical and computer engineering at UW–Madison, the researchers published details of these powerful, highly efficient integrated circuits today, May 27, 2016, in the journal Advanced Functional Materials.
The advance is a platform for manufacturers seeking to expand the capabilities and applications of wearable electronics — including those with biomedical applications — particularly as they strive to develop devices that take advantage of a new generation of wireless broadband technologies referred to as 5G.
With wavelength sizes between a millimeter and a meter, microwave radio frequencies are electromagnetic waves that use frequencies in the .3 gigahertz to 300 gigahertz range. That falls directly in the 5G range.
UESTC has co-training agreements in place with over 40 overseas institutions, such as Purdue University, University of Glasgow and University of Minnesota in the World Top 100 University League.
UESTC collaborates with more than 300 overseas institutions and multi-national companies. There are over 1,000 overseas companies collocated with UESTC in Chengdu, including over 100 Fortune 500’s, such as 3M, Dell, HP, Intel, Microsoft, Motorola, National Semi, Onsemi, ABB, Acatel, BAT, BHP, Ericsson, GSK, KLM, Nokia, Philips, Siemens, Shell, Canon, NEC, Samsung, Toyota, etc.
One team has already made a cat ‘disappear’ with a device that has huge military potential
Mainland scientists are increasingly confident of developing the world’s first invisibility cloak, using technology to hide objects from view and make them “disappear”.
The central government has funded at least 40 research teams over the past three years to develop the idea, which until now has largely been the stuff of science fiction and fantasy novels like the Harry Potter series.
The technology would have obvious military uses such as developing stealth aircraft, but Beijing believes the research could lead to wider technological breakthroughs with broader uses, scientists involved in the research said. The teams involved include researchers at Tsinghua University and the Chinese Academy of Sciences.
The main approaches are developing materials that guide light away from an object, creating electromagnetic fields to bend light away from what one is trying to hide and copying nature to make hi-tech camouflage materials.
