Snake-inspired robot uses kirigami to move
Who needs legs' With their sleek bodies, snakes can slither up to 14 miles-per-hour, squeeze into tight space, scale trees and swim. How do they do it? It's all in the scales. As a snake moves, its scales grip the ground and propel the body forward - similar to how crampons help hikers establish footholds in slippery ice.

New method for waking up devices
A device that's turned off doesn't suck battery life, but it also doesn't work. Now a low-power system that's always on the alert can turn devices on when they are needed, saving energy in the networked internet of things. As smartphone users know all too well, a sleeping device can still suck the life out of a battery.

Engineering Research Gives Optical Switches the ’Contrast’ of Electronic Transistors
Current computer systems represent bits of information - the 1's and 0's of binary code - with electricity. Circuit elements, such as transistors, operate on these electric signals, producing outputs that are dependent on their inputs. Agarwal's research on photonic computing has been focused on finding the right combination and physical configuration of materials that can amplify and mix light waves in ways that are analogous to electronic computer components.

New robots can see into their future
UC Berkeley researchers have developed a robotic learning technology that enables robots to imagine the future of their actions so they can figure out how to manipulate objects they have never encountered before. In the future, this technology could help self-driving cars anticipate future events on the road and produce more intelligent robotic assistants in homes, but the initial prototype focuses on learning simple manual skills entirely from autonomous play.

’Magnetoelectric’ material shows promise as memory for electronics
For News Media FOR IMMEDIATE RELEASE 11/29/17 Devices tend to store that information in two ways: through electric fields (think of a flash drive) or through magnetic fields (like a computer's spinning hard disk). Each method has advantages and disadvantages. However, in the future, our electronics could benefit from the best of each.

New theory could open potent new applications for light
One bar, two bars - it's an all-too-common problem. You're in a large building, driving in a remote area, or even right in the middle of a big city, but you can't stream video, check email or even make a phone call - because your cellular signal is weak. But the future may be different. University of Wisconsin-Madison electrical engineers have devised a new fundamental understanding that someday could lead to vast improvements in devices that gather or deliver information at any wavelength.
