The response/recovery times become longer with the addition of humidity protection layers while further decreasing particle size results in faster response times, but slower recovery times, associated with strong binding to more numerous sites. These devices require the implementation of heating While LIG can be used as the sensing element, due to its formation condition tunable active sites, this sensor morphology should not be favored over interdigitated designs, where gas sensing is mediated by the sensitizing material in the gap region. Centering the device around the critical conduction channel results in enhanced responses, as has been demonstrated in the initial works using MoS2 in both LIG channel (0.8 % response to 1 ppm of NO2, 60 o C) and LIG gap-based devices (22.9% to 250 ppb of NO2, room temperature) .
