Tapping Touch Screens to Generate Energy

Touch-screens are becoming ever-so-popular; people everywhere are tapping away on their smart phones, laptops, and iPads — and tapping frequently. So what if there were a way to capture the energy in all that tapping and use it to power the touch-screen device? Well researchers at Samsung and Sungkyunkwan are working on doing just that.

The researchers have combined flexible transparent electrodes with an energy-scavenging material. The resulting film-like substance can be printed over large areas and can potentially help power portable electronics.

The touch-screen display sensors that are commonly used today are rigid and power-consuming. Samsung’s team is trying to replace these with a flexible, self-powering sensor system. “The flexibility and rollability of the nano-generators gives us unique application areas such as wireless power sources for future foldable, stretchable, and wearable electronics systems,” says Sang-Woo Kim, professor of materials science and engineering at Sungkyunkwan University. Kim led the research with Jae-Young Choi, a researcher at Samsung Advanced Institute of Technology.

According to Technology Review, the power-generating touch screens are at least five years from the market. However some prototypes that have already been made can produce about a microwatt per square centimeter. Kim says this is enough for a self-powered touch sensor and “indicates we can realize self-powered flexible portable devices without any help of additional power sources such as batteries in the near future.”

Let's not stop at floors and roadways, Jamie. What about runways - with the rolling of the planes before they take off.
And also in the rails that trains travel on.

great idea. could we install them in the floors and roadways so that when we walk and drive we create energy LOL.
