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.
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
