Journal ArticleDOI
CMOS Interfacing for Integrated Gas Sensors: A Review
TL;DR: In this paper, the authors review the emerging field of CMOS gas sensors and focus upon the integration of two main gas-sensing principles, namely, resistive and electrochemical and associated circuitry by CMOS technology.
Journal ArticleDOI
Chemically reduced graphene oxide for ammonia detection at room temperature.
TL;DR: The synthesis of chemically reduced GO using NaBH4 and its performance for ammonia detection at room temperature and its use to manufacture a new generation of low-power portable ammonia sensors is reported.
Journal ArticleDOI
Hierarchical nanostructured WO3-SnO2 for selective sensing of volatile organic compounds.
TL;DR: A mixed metal oxide WO3-SnO2 nanostructured material synthesized in situ by a simple, single-step, one-pot hydrothermal method at 200 °C in 12 h is reported to demonstrate its superior sensing behavior towards volatile organic compounds (VOCs) such as ammonia, ethanol and acetone.
