Glass Fabric for Wearable Electronic Devices

Glass Fabric for Wearable Electronic Devices

Wearable computers or devices have been hailed as the next generation of mobile electronic gadgets, from smart watches to smart glasses to smart pacemakers. For electronics to be worn by a user, they must be light, flexible, and equipped with a power source, which could be a portable, long-lasting battery or no battery at all [...]

Mobile Device Can Sense a Stranger’s Touch

Mobile Device Can Sense a Stranger’s Touch

Passwords, gestures and fingerprint scans are all helpful ways to keep a thief from unlocking and using a cell phone or tablet. Cybersecurity researchers from the Georgia Institute of Technology have gone a step further. They’ve developed a new security system that continuously monitors how a user taps and swipes a mobile device. If the [...]

Logical Circuits Built Using Living Slime Molds

Logical Circuits Built Using Living Slime Molds

A future computer might be a lot slimier than the solid silicon devices we have today. In a study published in the journal Materials Today, European researchers reveal details of logic units built using living slime molds, which might act as the building blocks for computing devices and sensors.   Andrew Adamatzky (University of the [...]

Harnessing Everyday Motion to Power Devices

Harnessing Everyday Motion to Power Devices

Imagine powering your cell phone by simply walking around your office or rubbing it with the palm of your hand. Rather than plugging it into the wall, you become the power source. Researchers at the 247th National Meeting & Exposition of the American Chemical Society (ACS) presented these commercial possibilities and a unique vision for [...]

Graphene-Metal Sandwich Shrinks Electronics

Graphene-Metal Sandwich Shrinks Electronics

Researchers have discovered that creating a graphene-copper-graphene “sandwich” strongly enhances the heat conducting properties of copper, a discovery that could further help in the downscaling of electronics.   The work was led by Alexander A. Balandin, a professor of electrical engineering at the Bourns College of Engineering at the University of California, Riverside and Konstantin [...]

Thinnest LEDs Stronger, More Energy Efficient

Thinnest LEDs Stronger, More Energy Efficient

Most modern electronics, from flat-screen TVs and smartphones to wearable technologies and computer monitors, use tiny light-emitting diodes, or LEDs. These LEDs are based off of semiconductors that emit light with the movement of electrons. As devices get smaller and faster, there is more demand for such semiconductors that are tinier, stronger and more energy [...]

Computer Processors Power Efficiency Increased

Computer Processors Power Efficiency Increased

Have you ever wondered why your laptop or smartphone feels warm when you’re using it? That heat is a byproduct of the microprocessors in your device using electric current to power computer processing functions — and it is actually wasted energy.   Now, a team led by researchers from the UCLA Henry Samueli School of [...]

Auto-Fill for Gaps in Computer Programmers’ Code

Auto-Fill for Gaps in Computer Programmers’ Code

Since he was a graduate student, Armando Solar-Lezama, an associate professor in MIT’s Department of Electrical Engineering and Computer Science, has been working on a programming language called Sketch, which allows programmers to simply omit some of the computational details of their code. Sketch then automatically fills in the gaps.   If it’s fleshed out [...]
