Emerging applications driving innovations in gas sensing

Abstract

Purpose

This paper aims to show how a range of new and emerging applications are driving technological innovations in gas sensing.

Design/methodology/approach

Following a short introduction, this paper first considers developments relating to the needs of the military and security sectors. Wearable gas sensors, energy harvesting and self-powered gas sensors are then discussed. The role of gas sensors in mobile phones is then considered, together with details of new developments in sensors for carbon-dioxide, particulates and formaldehyde. Finally, brief conclusions are drawn.

Findings

This paper shows that a technologically diverse range of gas sensors is being investigated and developed in response to a number of new and emerging requirements and applications. The gas sensors respond to numerous inorganic and organic gases and vapours over a wide range of application-specific concentrations and are based on a multitude of often innovative sensing techniques, technologies and materials.

Originality/value

This paper provides technical details of a selection of gas sensor research activities and product developments that reflect the needs of a range of new and emerging applications.
