Rechargeable paper sheets could help rewrite the book on electricity storage

Using millions of tiny fibers of nanocellulose sheathed with a conductive polymer coating, scientists have created sheets of paper that can store significant amounts of electric charge. Dubbed "power paper," the material is able to be recharged many hundreds of time, and in mere seconds. It is also lightweight, requires no toxic chemicals or heavy metals to create, and may offer a renewable and prolific way to provide energy to all manner of devices.Read More

Flexible sensor made from chewing gum promises sensitive and versatile wearables

The small sensors found in wearables like fitness trackers and smartwatches are only becoming more versatile, from monitoring your heart rate to enabling gesture control. But a new sensor design could afford these devices even more flexibility, in more ways than one. By combining carbon nanotubes with used chewing gum, scientists have developed a sensing device that can pick up movements of the more flexible body parts, such as bent finger.Read More

Mstick LED light wand can wake you up and help you cook

The Mstick is a curious little device. It doesn't immediately appear to fall easily into any category and yet has multiple useful functions. It seems conspicuously unusual and yet strangely compelling. It's just an LED light stick. But it's also a timer, an alarm and a weather forecast display.Read More

Stretchable, programmable keyboard is tailor-made for wearable tech

Most of the keyboards we're familiar with are actually rather complicated pieces of hardware, usually invlolving springs and wiring for dozens of keys, but scientists at the University of Auckland in New Zealand have developed a streamlined, programmable keyboard using a soft, flexible and stretchable type of rubber known as a dielectric elastomer.Read More

Sensors to detect smouldering cables before they catch alight

They say that where there's smoke there's fire, but when it comes to electrical systems, by the time the smoke is detected, it's often too late. To raise the alarm early, a team of researchers from the Karlsruhe Institute of Technology and Karlsruhe University of Applied Sciences have developed hybrid sensors that detect gases given off by overheated plastic cables before too much damage can occur.Read More

Self-healing gel to repair and connect electronic circuits

Researchers at The University of Texas at Austin may have found a solution to one of the key problems holding back flexible, bendable electronics and soft robotics from mass production. Electronic circuits tend to crack and break when repeatedly subjected to bending or flexing, but a new self-healing gel may automatically repair these flaws as they develop.Read More
