A limit of detection of 170±40 ppm was demonstrated for methanol, below 8-hour workplace safety exposure limits (200 ppm). Rapid response times (t90=35 s @150 ppm methanol, 5 s recovery) and stability > 21 days were demonstrated, competitive with existing resource-intensive chemiresistive MOX sensors . These resource-and energy-efficient room-temperature chemiresistive SnO-LIG VOC sensors show significant potential for integration as low-power sensors for future wearable worker safety sensors or Edge-IoT applications .
