Combining inorganic and organic gas sensors elements: a new approach for multi‐component sensing

Abstract

Atmospheric dependent, gas sensitive resistors seem to be good candidates for detecting critical air pollution levels. Recently, great progress has been made in the development of various sensor types, but less attention seems to be paid to the integration of sensor elements with different characteristics. The aim of this international project is to develop a smart hybrid gas multisensor module for environmental applications, i.e. by combining classical thick-and thin-film elements with polymer-film based sensors and also a signal processing ASIC within a single package, which should be useful for all sensor types. The module should enable multi-sensor operation as well, when connected to an intelligent signal-processing unit.

Thin Films of Tret-Butyl Calixarene as Sensitive Materials for Organic Compound Detectors

“…Use of the molecular organic crystals opens wide possibilities for formation of sensitive architectures with predefined chemical functionality. Characteristic examples of this approach are given by the use of various cavitands, first of all calixarenes [12][13][14], which are very promising materials considering the possibility of optimization of their structure to match the analyte molecules' one [15][16][17][18][19][20]. These peculiarities of the molecular structure (presence of the nanocavities) and also the ability of molecular recognition of the organic compounds allow to utilize the calixarenes for creation of the gas sensors sensitive layers [21].…”
