Luminescent printed electronic devices can be very thin and flexible, which makes them feasible for new applications. Such EL-devices are already being applied in automobiles. For the school-implementation of printed electronics the authors have developed a flexible EL-device, which can be hand-printed using low-cost materials and methods. http://pubs.sciepub.com/wjce/9/4/2/wjce-9-4-2.pdf printed electronics electroluminescence semiconductor hands-on experiment
