Laser-induced graphitic carbon (LIG) is an attractive candidate electrode material for replacing traditionally manufactured electrodes. Discovered in 2014, this laser graphitization method enables site-specific direct-write formation of highly porous, three-dimensional, conductive carbon electrodes on suitable polymer substrates . LIG was initially formed from polyimide, a synthetic polymer, using a 10.6 m CO2 laser. The laser treatment locally increases the temperature and pressure of the precursor polymer, producing the characteristic porous graphitic LIG material . The complexity of the formation process necessitates multifactor optimization routines due to the multiple interrelated factors controlling morphology and behavior . The resulting carbon material has shown great potential for electrochemical sensing , and energy storage and more recently for gas sensing . However, damaging/costly mechanical/silver-paint electrical contacts have been necessary to utilize the resulting carbon material, until recent direct-write, back-contacting methods were developed . Subsequent works have demonstrated its formation from treated wood and food products ; as-harvested renewables, e.g., cork ; and biopolymers, e.g., chitosan .
