Researchers at UC Berkeley have been working on an amazing paper-thin e-skin display. What makes this display especially unique is the fact that it is quite flexible and it responds to touch. Don’t think of it responding to touch like the average smart phone, rather, pressure on the e-skin will cause it to light up. Check out this amazing video below of the e-skin in action.
Research team leader Ali Javey has worked with his team to develop this new technology. “With the interactive e-skin, we have demonstrated an elegant system on plastic that can be wrapped around different objects to enable a new form of human-machine interfacing,” said Javey.
The sky is the limit with this new kind of technology. Some hope that it could be used as an interactive wallpaper or as an additional means to control electronics in a car. Currently, the test samples are 16 x 16 pixels that are embedded with organic LEDs that light up when touched, but there is certainly potential for much more.
How were these devices created? Engineers started by curing a thin layer of polymer and placing it atop a silicon wafer. After the plastic hardens the whole item is run through a fabrication tool to insert all the electronics. Next, the plastic layer is peeled from the silicon base leaving a freestanding film with all the electronics already embedded.
Javey also added, “The electronic components are all vertically integrated, which is a fairly sophisticated system to put onto a relatively cheap piece of plastic. What makes this technology potentially easy to commercialize is that the process meshes well with existing semiconductor machinery.”
