title = "Laser-induced porous graphene gas sensing platform toward the electronic nose",
abstract = "Measurements from the gas-sensitive nanomaterials typically involve the use of interdigitated electrodes. A separate heater is often integrated for fast recovery. However, their use increases fabrication complexity. Here, a novel gas sensing platform based on a highly porous laser-induced graphene (LIG) pattern is reported. The LIG gas sensing platform consists of a sensing region and a serpentine interconnect region. A thin film of metal coated in the serpentine interconnect region significantly reduces its resistance, thereby providing localized healing in the sensing region. Dispersing nanomaterials with different selectivity results in an array to potentially deconvolute various components in the mixture. Systematic investigations of various nanomaterials demonstrate the feasibility of the LIG gas sensing platform. Taken together with the stretchable design in the serpentine interconnects, the demonstrated system could open new opportunities in bio-integrated electronics.",
