Disney Develops Energy-Harvesting Finger-Touch Tech
11/11/2013

The Paper Generator harvests energy when the user rubs, taps, or slides a finger over a thin sheet of Teflon sandwiched between two thin sheets of reactive material. Invented by researchers at Disney Research, the technology could be used to power small devices or interactive technologies for e-games or displays.(Source: Disney Research)

"you make a very good point. If enough power could be generated to power the entire toy and not just some kind of light or gizmo on the top, then this technology would be even more useful."

Elizabeth, I had seen similar thing in Chinese toys. Toys are working with a mechanical key and we have to key it before it starts. When it performs, the mechanical movements are converting into electrical energy for performing other functionalities like sound, light, obstruct detection etc.

"It does seem like it is the touch and the movement that combine to generate energy in Disney's method."

Elizabeth, that's great. Then that's a piezoelectric technology, where any form of stress and pressure can be convert into equivalent form of electricity.

Conductive paints sound like a really interesting idea, too, Jack B. And a company called Pavegen already has invented energy-harvesting tiles that use people's footfalls, which is really quite cool: http://www.designnews.com/author.asp?section_id=1386&doc_id=262295

Thanks for the comment and your compliment.

It will be interesting to see where this could lead to in the future. With conductive paints, and paper circuits the printed page may never be the same. Scaling it up you could harvest the energy of people walking over a surface or traffic rolling over a highway. Great write-up!

Battar,

Great idea. As for the TV watching, I rarely watch, but the TV is 200+ channels of uselessness. When I do sit down to watch, the remote is in constant use channel surfing. I usually end up turning off the TV and working on one of my hobbies.

Mydesign,

              you say " Some mechanism for converting the toy activity to a self powering mode will be very good"

That sounds like a recipe for a perpetual motion machine. I'm waiting to see the prototype. On the other hand, if you have an idea how I can harvest my 3 boys' excess energy for useful purpose (there is plenty, efficiency is not an issue), then you have my full and undivided attention.

GTOlover,

               Has it ever occurred to you to place a selenium PV cell on the remote and harvest the light energy emitted by your TV to power the device?

If you find youself periodically replacing the batteries on the remote, it's a sure sign that you watch too much TV.

Now that is a fine idea, GTOLover. How annoying is it to continuously push the button of the remote to try to change a channel with no success and then realize you're out of batteries and have to go searching around for some. I'm sure that can be done.

Sounds like a good idea, Cadman-LT, but how would that work exactly? :)

How about energy harvesting the button push of the TV remote! Never have to replace the remote control batteries.

Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?

In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Biomedical engineering is one of the fastest growing engineering fields; from medical devices and pharmaceuticals to more cutting-edge areas like tissue, genetic, and neural engineering, US biomedical engineers (BMEs) boast salaries nearly double the annual mean wage and have faster than average job growth.
