Ammonia Gas Sensor Fabricated by Multifunctional ZnO/GO Nanocomposites for Long‐Term, Self‐Powered Monitoring

open access: yesAdvanced Science, EarlyView.
Zinc oxide/graphene oxide (ZnO/GO) nanocomposites serve as a gas‐sensitive film for ammonia sensing and as high‐performance electrode materials in supercapacitors, simultaneously. A wearable contact‐separated triboelectric nanogenerator is designed to directly drive the ZnO/GO nanocomposites‐based ammonia sensor.

Naked‐Eye Visual Warning of ppmv‐Level Fault‐Free Humidity Upper Limit

open access: yesAdvanced Science, EarlyView.
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
