“…Experimental results have shown that this system can detect very low concentrations of toluene (10 ppb) within a short data acquisition time (measurable every 20 seconds), and results are independent of temperature and humidity. In another electrochemical approach, solid-state sensors may be used for developing reliable, sensitive, cost-effective, portable and simple to operate air toxicity sensors (92). However, the major focus of research in this field is concentrating on screen printing technologies, which underpins the progressive drive towards real miniature, portable and commercially available devices.…”

A vast majority of people today spend more time indoors than outdoors. However, the air quality indoors may be as bad as or even worse than the air quality outside. This is due to the continuous circulation of the same air without proper ventilation and filtration systems, causing a buildup of pollutants. As such, indoor air quality monitoring should be considered more seriously. Indoor air quality (IAQ) is a measure of the air quality within and around buildings and relates to the health and comfort of building occupants. To determine the IAQ, computer modeling is done to simulate the air flow and human exposure to the pollutant. Currently, very few instruments are available to measure the indoor air pollution index. In this paper, we will review the list of techniques available for measuring IAQ, but our emphasis will be on indoor air toxicity monitoring.

“…Poly (ionic liquid)-wrapped single-walled carbon nanotubes have been found to be sensitive for carbon dioxide detection at low concentrations of CO 2 (500 ppt) [67][68][69][70][71][72]. The chemiresistive dynamic response of the carbon nanotubes is shown in Figure 18 (Type 1 sensor), where the mechanism for sensing is based on the interaction between BF 4 anion and CO 2 .…”

“…Mason et al [71] developed solid-state reference measuring electrodes and a beta alumina electrolyte substrate with a provision for heating, and made measurements at a temperature of 530 • C. At this temperature, the carbon dioxide sensing was found to be selective from other gases. A novel electrochemical sensor using a ceramic-type component of Na-β/β" alumina and a reference electrode of glass sealed elemental Na has been developed for measuring CO 2 gas in the temperature range of 300 to 600 • C [72] with a response time of seconds to minutes.…”

With the increasing utilization of fossil fuels in today’s technological world, the atmosphere’s concentration of greenhouse gases is increasing and needs to be controlled. In order to achieve this goal, it is imperative to have sensors that can provide data on the greenhouse gases in the environment. The recent literature contains a few publications that detail the use of new methods and materials for sensing these gases. The first part of this review is focused on the possible effects of greenhouse gases in the atmosphere, and the second part surveys the developments of sensors for greenhouse gases with coverage on carbon nano-materials and composites directed towards sensing gases like CO2, CH4, and NOx. With carbon dioxide measurements, due consideration is given to the dissolved carbon dioxide gas in water (moisture). The density functional calculations project that Pd-doped single-walled carbon nanotubes are ideal for the development of NOx sensors. The current trend is to make sensors using 3D printing or inkjet printing in order to allow for the achievement of ppb levels of sensitivity that have not been realized before. This review is to elaborate on the need for the development of greenhouse gas sensors for climatic usage by using selected examples.

“…Solid electrolytes are widely studied because they are accurate and reliable, small and light, exible to install and easy to use. 5 Yttria stabilized zirconia (YSZ) devices have high chemical and thermo mechanical stability. 6 For thick lm applications, the operating temperature of the YSZ is more than 600 C. 6 Recently, the authors reported a SnO 2 micro-electro mechanical systems (MEMS) gas sensor.…”
