Environmental control with the aid of sensor technologies for GAS sensing


Foreseen Results

AVANGARD will develop a substrate for the common use by all partners. The substrate will be designed in order to be produced using the extended microelectronics technological lines existing in AVANGARD and will be available to all partners starting from the second year. In the same time AVANGARD will test the possibilities of gas sensors preparation by thin-film techniques. The final result of the project will consist in novel gas sensors for the monitoring of indoor and ambient air quality with enhanced stability and selectivity. There will be different constructive solutions from the point of view of the substrate and the technology of obtaining the sensing layer.
The objective of the project consists in the finding of new methods for the monitoring of indoor and ambient air quality by using novel types of gas sensors. The project aims to combine the knowledge of partners from EU and CCE/NIS countries in a synergetic research during which a double transfer will take place. The EU countries will transfer modern sensor testing equipment - one set up for routine and response time measurements and one set up for long term measurements - and knowledge about sensor quality requirements, in line with European environmental policy. They also will train young doctoral students of CCE/NIS partners. The CCE/NIS countries will transfer their extensive knowledge about sensitive materials properties and technological methods for obtaining such materials.
IPC will ensure the coordination of the project. The gas stations will be constructed in IPC by doctoral students from CCE/NIS partners, under IPC coordination. IPC will train these students in using the gas stations and will transfer all the needed software. IPC will coordinate the change of information between partners and ensure the concentration of their efforts. IPC will also assist the CCE/NIS partners by forming surface spectroscopical studies and testing of their samples. INFM will assist the CCE/NIS partners in their efforts by making bulk spectroscopic analysis of their materials and by coordinating the set up of gas testing stations for long term measurements.
The IPTM efforts will concentrate on the study of a new diode-type sensor, which will be operated in the reverse conduction regime. The main advantage of this new sensor will be the control of the sensitivity towards water vapour and reducing gases by means of suitable choice of the reverse applied voltage and of the temperature of operation. The already obtained samples, using tin oxide as sensing material and in a geometry similar to the one of commercial Figaro gas sensors, show stable asymmetric I-V characteristics. IPTM will attempt to use also the materials prepared by SRIPCP and the substrate prepared by AVANGARD.
The SRIPCP efforts will go on further to the development of sol-gel technologies for obtaining ceramic sensitive materials on the basis of metal oxides. Sol-gel technique offers a better control of sensors microstructure and a prospective of lowered dimension and as a consequence a low power consumption. It will perform also investigation of the gas-sensitive films to establish the features of the oxide films structure, the electronic states of the elements in the mixed oxide matrix, the character of structure and phase transformation under thermal treatment of oxide films in different gas ambient and the influence of the factors mentioned above on the gas-sensitive properties of the films. It will also assist the partners in their efforts to use its materials.
