Thin-Film Device Eyed as Power Source for Wearable Tech
6/10/2014

A thin-film energy storage device, seen attached to a polymer backing, retains its battery-like and supercapacitor-like qualities even after being flexed 1,000 times, according to tests at Rice University. Rice chemist James Tour led the team that developed the supercapacitor, which can be used to power wearable electronics and flexible devices.  (Source: Jeff Fitlow/Rice University)

Yes, I think that could be a good application, too, Cadman-LT. A lot of these new power sources are aimed at both wearables, which often demand flexibility themselves, and the next generation of flexible mobile devices that are the evolution of the hard, inflexible ones we have now. I've written a lot about some of these alternative power sources.

Thanks, mrdon. Your observation is interesting and correct. It's funny how something that's been around for a long time and is, as you point out, simple, could become the default future power source for some of the most innovative new electronics.

mrdon, I think it just may just fix the flexible, roll-up screen problem. It's been a power issue forever, this could solve it.

I agree. Its amazing how a capacitor has become an alternative power source because of its electrical charge storage capabilities. Talk about a simple yet powerful solution.

The capacitor is an innovative way of creating an alternative power source because of its ability to store charges and to release them when an electrical load is connected to them. What a simple yet powerful solution. I'll definitely be sharing this article with my students to illustrate how small electronic components can solve today's tech challenges. This was a nice article to read.

Yes, Cadman-LT, you're right. Necessity is the mother of invention here. With electronic devices taking on smaller and more varied shapes and sizes, so, too, are power sources.

Elibeth, great article. This sounds good like a good option for the flexible screens. I think one of their biggest hurdles was power.

This is another advancement in power sources for wearable tech, which range from small devices like this to energy harvesters. It will be interesting to see going forward if certain types of devices are adopted more than others, or if a combination of devices is used depending on the application.
