The tattoo biosensor for monitoring lactate levels that has been converted into a sweat-po...

Last year, researchers at the University of California, San Diego (UCSD) unveiled a sensor imprinted on a temporary tattoo that, when applied to the skin, is able to continuously monitor lactate levels in a person's sweat as they exercise. Now the research team has leveraged the technology to create a biobattery powered by perspiration that could lead to small electronic devices being powered by sweat.  Read More

The ZeroHour XD offers four different lighting modes

According to its creators, not only can the ZeroHour XD tactical flashlight blast 1,000 lumens of light into the evening darkness for up to six hours, it can charge an iPhone seven times (though it won't do both on the same charge). The flashlight includes a removable, 10,200-mAh battery pack that doubles as a dual-USB charger and features a modular design that allows the size of the device to be altered depending on the need at hand.  Read More

Thanks to zinc oxide nanorods, phones may someday be able to recharge using the sounds aro...

Four years ago, we first heard about how Korean scientists had proposed using sound to charge mobile phones. They explained that it could be done via a piezoelectric effect, in which zinc oxide nanowires converted sound-caused vibrations into electricity. At the time, the researchers couldn't generate enough of a current to actually charge a phone. Now, however, scientists from Nokia and Queen Mary University of London (QMUL) have succeeded in doing so.  Read More

A Kickstarter campaign has been launched for the Scribble Ink Pen that allows people to sc...

Back in May we reported on plans to create the Scribble – a pen that can scan and reproduce any color you can find on the fly. After the project smashed its Kickstarter target in just five hours, those plans are now one big step closer to reality.  Read More

The Yepzon child tracker

A child gone missing is every parent’s worst nightmare. Thankfully, digital technology can offer a helping hand. Devices like Hereo, Belluv and Mommy Here have been created to help parents keep their little ones under their digital thumbs. The latest to join the ranks is Yepzon from Finland, a positioning device currently at the type-approval stage. Its makers are seeking 50 testers all over the globe to see how it works in the field.  Read More

The tinyTelsa musical Telsa coil from oneTesla

The folks who successfully crowdfunded a DIY singing Tesla coil kit last year have taken to Kickstarter again to bring a smaller version into production. Like its older and bigger brother, the tinyTesla shoots out bolts of artificial lightning while playing MIDI music using the electricity itself. It looks like that polyphonic MIDI version of Danger High Voltage by Electric Six might just come in handy after all.  Read More

The WristBow Mk II stores multiple carbon fiber darts in its ammo clip, which drop into pl...

When we last heard from German cyberpunk weapons hobbyist Patrick Priebe, he'd made a set of X-Men-inspired goggles that incorporated burning lasers. Some time before that, however, he showed us a wrist-mounted, laser-sighted crossbow that he'd created. Now, he's just completed a new-and-improved "semi-automatic" take on that crossbow.  Read More

Researchers have developed a wireless system that directly powers Wi-Fi connections using ...

One of the advantages of the "connected world" is that myriad different devices can interact with each other over Wi-Fi to exchange data, control equipment, and generally lay the foundations of the Internet of Things of the not-too-distant future. Unfortunately, on the downside, all of the Wi-Fi connections need power to operate, and this severely restricts the pervasiveness of this technology. However, researchers at the University of Washington have developed a system that they say eliminates the need for power supplies for these connections by using what is known as radio frequency (RF) backscatter technology.  Read More

Nanospheres were specifically created to protect the lithium from reacting chemically with...

Stanford University researchers claim to have created the first stable pure lithium anode in a working battery by using carbon nanospheres as a protective sheath to guard against degradation. As a result, the researchers predict that commercial developments may eventually result in anything up to a quadrupling of battery life in the not-too-distant future.  Read More
