Researchers at the Ulsan National Institute of Science and Technology in Korea have developed, what they claim to be, the world's first imprintable and bendable lithium-ion battery. The move should hasten the adoption of mobile devices with flexible displays, such as Samsung’s Youm flexible OLED, and potentially other flexible devices that are beginning to emerge.
Wearable Li-ion batteries, that's cool, but won't be so cool if they overheat and light your heated jacket on fire! Laptops, Chevy Volt, airplanes, etc. are pretty good indicators that Li-ion has its drawbacks. Now, imagine, someone's kid gets burned, even a little bit while wearing his cool LED jacket, or the coat room burns up during a night out. Dunno...I think that Li-ion tecnology will have a ways to go yet before we can ubiquitously start putting it into flammable, wearable goods. Try putitng a 9V dry cell in your pocket with a bit of change...yeowch!
Interesting observation, and you're right. It seems for awhile that device design was going in the direction of thinner, smaller and more sleek. Now that a lot of companies have got that down, it's time to make them flexible. I look forward to see where this trend will take us.
Ann, you are right. Wearable & portable electronic devices may be more benefitable because the devices become handier and hence easy to carry either in pouch or hand bag. How about the durability or life time of such cells/battery when it becomes bendable?
Elizabeth, it seems that now a day's all inventions are happening in a similar direction to bent the existing technology. Last month we read about foldable screen and now about batteries. Hope this will lead to a technology to bendable devices, so that we can bend and keep the device in our wallet or hand bag.
There are a lot of apps for a bendable battery aside from displays and touch screens, and they somewhat parallel the apps for bendable displays themselves: smart fabrics, wearable electronics, conformable signage, for example.
Duh, I didn't even think of that, TJ, but of course! And I actually reported on some of these electronic-embedded fabrics etc. It didn't occur to me at the time this would be a good application, but you're right, it certainly would make these types of things much more comfortable to wear by eliminating the need for a hard, bulky battery.
Elizabeth, I think it will go beyond phones and tablets. In the past year Design News has reported on various fabrics and clothing with embedded electronics. A flexible battery seems a perfect power source for smart clothing.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
