This article presents the design, implementation, and experimental evaluation of a novel measurement circuit for four-wire resistive sensors, such as resistance temperature detector (RTD) thermal ...

We proposed and demonstrated an optical component-free dual-gas quartz-enhanced photoacoustic spectroscopy (QEPAS) sensor. Two mid-infrared interband cascade lasers (ICLs) emitting at 4.59 μm were ...

Improve this page Add a description, image, and links to the mq2-gas-sensor topic page so that developers can more easily learn about it.

The CMOS-MEMS Schottky gas sensor is designed and implemented using a standard commercially available CMOS process, along with post-CMOS processes. The proposed gas sensor consists of open ...
