University of Missouri engineers are building a nuclear battery the size of a penny. Their aim is to develop a long-lasting power source for tiny sensors, actuators, and labs-on-a-chip. While nuclear batteries sound, er, problematic, they're actually relatively common in larger form factors to power pacemakers and instruments aboard space vehicles. From MU News Bureau:
(Professor Jae Kown's) innovation is not only in the battery’s size, but also in its semiconductor. Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.

“The critical part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure of the solid semiconductor,” Kwon said. “By using a liquid semiconductor, we believe we can minimize that problem.”
In the future, they hope to increase the battery’s power, shrink its size and try with various other materials. Kwon said that the battery could be thinner than the thickness of human hair.
Lured by the internet’s pervasive insistence that it represents a superior, more comfortable typing experience, I recently went back to an old-timey mechanical keyboard. This was a mistake. I am now a hamfisted ASCII jazz disaster.
SpareOne Emergency Phone is a basic cellphone powered by AA batteries. This gives it a relatively short time on a charge, but means that it will have a charge after being stuffed in a drawer or glove box for months. I came across this during my search for the perfect basic phone, but be warned: […]
Low-cost carrier Easyjet has prototyped “Sneakairs,” a pair of shoes that have small vibrating motors and Bluetooth links; they work in concert with your mobile phone’s mapping app, buzzing left or right when it’s time to turn, and twice if you’ve gone the wrong way.
Jared Sinclair developed the RSS reader app Unread, which made $10,000 in its first 24 hours on the iOS market. And we’ve all heard the story of Flappy Bird developer Dong Nguyen, whose creation was reportedly earning $50,000 a day at the height of its 2013 explosion. While those are rare examples, they’re also testament to the […]
If you or your company’s IT system are besieged by black hat cyber attacks, an ethical hacker might be all that stands between crippling damage and a company’s long-term prosperity. It’s no wonder that the market for IT security specialists is exploding. Certification is the key – so learn the tenets of ethical hacking and get […]
