Naked-Eye Visual Warning of ppm<sub>v</sub>-Level Fault-Free Humidity Upper Limit. [PDF]
Adv Sci (Weinh)In this study, based on the urgent need in many critical fields for ppmv‐level fault‐free humidity upper limit (ppmv‐FFHUL) monitoring, an innovative threshold gated humidity sensing technology was developed. It exhibits superior portability (as thin and light as paper) and highly economic feature (without auxiliary instruments at all), and can achieve
