Paper electronics: a sustainable multifunctional platform

Cellulose is the Earth's major biopolymer and it is of tremendous global economic importance, especially in Europe representing 30% of the world's total production. Nevertheless the use of paper can be expanded tremendously if electronic, sensor and display applications could also be applied on it and by it. Some promising applications have been already demonstrated, like solar cells, displays, capacitors, actuators, gas sensors, magnetic devices, biosensors, food packaging and batteries [1]-[6].
