Paper-based resistive touchpad for electronic applications
In this, the touch location is identified by the change in the output resistance of a particular place and is flexible from both the sides because the building blocks are composed of soft materials such as paper and PDMs While the graphite-coated paper layers act as conductive layers in the touchpad, the transparent coating of PDMS, in the middle of the papers, acts as a dielectric layer between them. It is a resistive touchpad where the touch area comprises two pieces of graphitecoated paper, acting as two conductive surfaces, and comes in contact to give a particular output resistance at the touch location. Here, the conductive papers are coated with a transparent polymer, acting as a protective coating; the conductive papers are separated by patterned thin film of non-conducting polymer and, the polymer coating is the only transparent element in the device. The prototype can reduce the cost for a wide range of applications such as mobile phones, television screen, ATMs, laptops, computers, healthcare devices and i-pads
