Laser-induced Graphene(LIG) is a porous material obtained by graphenization of polymeric substrate. The fabrication approach consists of exploiting the use of pulsed-laser writing, causing the absorpion of long-wavelength radiation, which produces photo-thermal effects. The purpose is to obtain Graphene from a wide range of carbon precursors under ambient atmosphere conditions. LIG opens up a lot of new ways in electronics, especially for flexible, biodegradable and edible electronics. Thanks to this technique conductive patterns can be obtained on planar and flexible substrates and used as electrodes for strain sensors and supercapacitors (SCs). The substrate used, in my thesis, is polydimethilsyloxane(PDMS) because of its wide use due to its rheological properties, low cost and biocompatibility.
