Researchers from the University of South Carolina have been able to convert a regular, store-bought shirt into a capacitor, which means that the very clothes we wear could, someday, power the myriad of devices we use in our everyday lives.
While wearable devices are currently iffy at best, we do carry a handful of devices on our person, including our smartphones, personal music players, and to some extent, tablets. Noting that electronics are fast becoming part of our wardrobe, a team led by the USC’s Xiaodong Li and Lihong Bao are experimenting on ways how fabric can act as flexible energy sources for devices.
One day our cotton T-shirts could have more [...]
When it comes to the idea of flexible smartphones or wearable electronics, you have to remember that in order for everything to work all components must be truly flexible as well. While we’ve already seen demonstrations of flexible displays, it seems that Professor Keon Jae Lee from the Korean Advanced Institute of Science and Technology has also created a flexible battery that can be folded, bent and distorted in a variety of ways without losing any of its energy or ability to maintain a charge.
Apparently, these lith-ion batteries are actually made by printing them onto special film. This new technology could truly lead to many new [...]
What started as a portable means to make and receive calls and text messages, has now been replaced with the desire for a lot of other technologies such as cameras and mp3 players. Our smartphones have become an essential part of our lives, which we use for almost everything. Browsing the internet, checking e-mail, watching videos, listening to music, taking pictures and videos, and gaming, we can do it all on one single device.
What gives us the ability to do so, is the rapidly changing handheld device technology, such as the much faster dual-core and quad-core processors we now have available to us. Unfortunately, one [...]
It’s easy to get carried away with our mobile devices. There are a number of things that can just take up countless hours of your time. Browse the Internet and get lost in the maze of Wikipedia’s articles or TVTropes’ trope pages. Curious about the new TV series everyone is hyped up about? View videos on YouTube or download the series yourself to see why everyone is crazy over this show. Next thing you’ll know, you’ll be tapping on the Next button without noticing the time. Or, you can sit back and curl up with a number of ebooks. Flip page after electronic page to see to the end the adventure you’ve embarked on.
Unfortunately, your [...]
With all of our gaming, constant email checking, and Facebook abuse, it’s a wonder that smartphone batteries can do the job all day. Researchers at Rice University have created a battery that consists of 5 layers, which can be applied by spraying to just about any surface. This new version of the battery will pave the way for more flexible devices and possibly even new types of designs.
To demonstrate the new technology, researchers applied the spray-on battery on nine bathroom tiles, which managed to power a set of LEDs that spelled out “RICE” for a full six hours. The [...]
There are some people who don’t like smart phones. It isn’t because they don’t like the touch sensitive screen, it’s not an ease of use issue, but rather they don’t like the battery life. In the good old days of feature phones, you could charge up your phone once a week, you could talk for hours, and, if you battery showed only one bar left, you knew it would work for the rest of the day. But not so with smartphones. With a nice bright display to power, plus Wi-Fi, plus GPS, and of course 3G or even 4G, a smart phone battery might last a day, maybe two.
A typical feature phone might use a 1100mAh battery, where as a smart phone could have [...]
Recent advances in battery technology could mean that the next generation of batteries will last ten times longer than current batteries.
The new tech known as Lithium-air batteries use the oxygen in the air as part of the chemical reactions that make batteries work. The biggest hurdle up until now has been that the oxygen also reacts with other parts of the battery causing them to deteriorate.
But the latest research has turned up an electrolyte material that doesn’t react with oxygen. This means that, in the lab at least, Lithium-air batteries are stable and can be charged-discharged multiple times without a performance drop. If these batteries ever make [...]
For me, and probably for every tech user out there, there are two major gripes with smartphone batteries.
First, they drain down to empty in no time; second, it can take hours to recharge them again. Well, Prieto, a Colorado-based startup, claims that it has developed a technology that could solve my two gripes, and revolutionize the battery market in the process.
Prieto’s objective is to manufacture and sell a new type of lithium-ion battery that lasts up to five times longer than standard batteries. Moreover, the technology supposedly allows for super-fast recharge times as well. According to GigaOm, the company, which is the brainchild of Colorado State [...]
