Abstract

The invention relates to a paper-based printed electronic device comprising one or more sheets of paper that is impregnated with a resin in way to fill the voids (or pores) of porous networks of cellulose fibers and in particular to saturate said porous networks of cellulose fibers, as well as to coat the outer surfaces of the printed electronics with said resin. A fully encapsulated electronic device is obtained which is protected against external environmental and physical damages such as against moisture and oxygen and has acquired sufficient resistance to tearing. The impregnated and encapsulated electronic device can then be successfully integrated into an object in a form of a flat or curved monolithic structure. This may especially be achieved through a lamination process, as said device sustains high pressure, high temperature, does not create bubbles, does not delaminate, and can be fully embedded into an end product.
