Technology can be awkward. Our pockets are weighed down with ever-larger smartphones that are a pain to pull out when we’re in a rush. And attempts to make our devices more easily accessible with smartwatches have so far fallen flat. But what if a part of your body could become your computer, with a screen on your arm and maybe even a direct link to your brain?

Artificial electronic skin (e-skin) could one day make this a possibility. Researchers are developing flexible, bendable and even stretchable electronic circuits that can be applied directly to the skin. As well as turning your skin into a touchscreen, this could also help replace feeling if you’ve suffered burns or problems with your nervous system.

The simplest version of this technology is essentially an electronic tattoo. In 2004, researchers in the US and Japan unveiled a pressure sensor circuit made from pre-stretched thinned silicon strips that could be applied to the forearm. But inorganic materials such as silicon are rigid and the skin is flexible and stretchy. So researchers are now looking to electronic circuits made from organic materials (usually special plastics or forms of carbon such as graphene that conduct electricity) as the basis of e-skin.

Retired U.S. Air Force Colonel Gene Lee, in a flight simulator, takes part in simulated air combat versus artificial intelligence technology developed by a team from industry, the U.S. Air Force, and University of Cincinnati.

The U.S. Air Force got a wakeup call recently when AI software called ALPHA — running on a tiny $35 Raspberry Pi computer — repeatedly defeated retired U.S. Air Force Colonel Gene Lee, a top aerial combat instructor and Air Battle Manager, and other expert air-combat tacticians at the U.S. Air Force Research Lab (AFRL) in Dayton, Ohio. The contest was conducted in a high-fidelity air combat simulator.

According to Lee, who has considerable fighter-aircraft expertise (and has been flying in simulators against AI opponents since the early 1980s), ALPHA is “the most aggressive, responsive, dynamic and credible AI I’ve seen to date.” In fact, he was shot out of the ai r every time during protracted engagements in the simulator, he said.

Definitely could see QC being Blackberry’s achilles heal.

WATERLOO — Advances in quantum computing could present a huge challenge to BlackBerry’s biggest competitive advantage — its vaunted security software that has never been hacked.

This seldom talked-about subject was raised recently by John Thompson, the associate vice-president for research at the University of Waterloo. Thompson was listening to a presentation by Mike Wilson, a senior vice-president and chief evangelist for BlackBerry, at a medical technology conference in Kitchener about a month ago.

Both quantum computing and BlackBerry have deep roots in Waterloo. BlackBerry pioneered the smartphone industry and the wireless Internet from its suburban office parks in Waterloo.

What if industrial waste water could become fuel? With affordable, long-lasting catalysts, water could be split to produce hydrogen that could be used to power fuel cells or combustion engines.

By conducting complex simulations, scientists showed that adding lithium to aluminum nanoparticles results in orders-of-magnitude faster water-splitting reactions and higher hydrogen production rates compared to pure aluminum nanoparticles. The lithium allowed all the aluminum atoms to react, which increased yields (Nano Letters, “Hydrogen-on-demand using metallic alloy nanoparticles in water”).

For clarity, the water molecules were removed from the snapshot. Simulations were carried out at the Argonne Leadership Computing Facility.

With a radio specifically designed to communicate through tissue, Professors David Blaauw (http://web.eecs.umich.edu/faculty/blaauw/) and David Wentzloff (http://web.eecs.umich.edu/~wentzlof/) from the University of Michigan’s Electrical and Computer Engineering Department (https://www.eecs.umich.edu/ece/) are adding another level to a computer platform small enough to fit inside a medical grade syringe.

With this enabling technology, real time information can be applied to devices monitoring heart fibrillation as well as glucose monitoring for diabetics.

This new radio, designed by Graduate Student Research Assistant Yao Shi, can transmit information from inside the body up to one foot to a data base receiver, more than 5 times the distance from any known radio of equal size.

ABOUT THE PROFESSORS
David Blaauw received his B.S. from Duke University in 1986 and his Ph.D. from the University of Illinois, Urbana, in 1991. From 1993 until August 2001, he worked for Motorola, Inc. in Austin, TX, where he was the manager of the High Performance Design Technology group. Since August 2001, he has been on the faculty at the University of Michigan where he is currently a full Professor. His work has focused on VLSI design with particular emphasis on adaptive and low power design.

David D. Wentzloff received the B.S.E. degree in Electrical Engineering from the University of Michigan, Ann Arbor, in 1999, and the S.M. and Ph.D. degrees from the Massachusetts Institute of Technology, Cambridge, in 2002 and 2007, respectively. Since August, 2007 he has been with the University of Michigan, Ann Arbor, where he is currently an Associate Professor of Electrical Engineering and Computer Science. His research focuses on RF integrated circuits, with an emphasis on ultra-low power design.

Miniaturization is one of the most world-shaking trends of the last several decades. Computer chips now have features measured in billionths of a meter. Sensors that once weighed kilograms fit inside your smartphone. But it doesn’t end there.

Researchers are aiming to take sensors smaller—much smaller.

In a new University of Stuttgart paper published in Nature Photonics, scientists describe tiny 3D printed lenses and show how they can take super sharp images. Each lens is 120 millionths of a meter in diameter—roughly the size of a grain of table salt—and because they’re 3D printed in one piece, complexity is no barrier. Any lens configuration that can be designed on a computer can be printed and used.

Deep inside the electronic devices that proliferate in our world, from cell phones to solar cells, layer upon layer of almost unimaginably small transistors and delicate circuitry shuttle all-important electrons back and forth.

It is now possible to cram 6 million or more transistors into a single layer of these chips. Designers include layers of glassy between the electronics to insulate and protect these delicate components against the continual push and pull of heating and cooling that often causes them to fail.

A paper published today in the journal Nature Materials reshapes our understanding of the materials in those important protective layers. In the study, Stanford’s Reinhold Dauskardt, a professor of materials science and engineering, and doctoral candidate Joseph Burg reveal that those respond very differently to compression than they do to the tension of bending and stretching. The findings overturn conventional understanding and could have a lasting impact on the structure and reliability of the myriad devices that people depend upon every day.
