Electronic Chemical Imaging for Automotive Applications

Objective



Objectives and content
The objective of the project is to develop a sensor system that is capable of analysing complex gas mixtures in the cabin of a petrol or diesel automotive vehicle. A similar device will be developed to analyses exhaust gases. The ultimate cost of the system requires the development of an integrated sensor system that harnesses several key chemical sensing technologies. The sensor system will be specified by Fiat and VDO and will consist of a hybrid integrated sensor chip that combines the material technologies of the University of Warwick (conducting polymers), University of Linkoping (MOSFET's) and the University of Tubingen (metal oxides/dielectrics) and will respond to gases and vapours of nuisance or health value inside cars (e.g. mixtures of CO, NOx, ketones, aldehydes and benzene).
The control and interface circuitry will initially be fabricated on a second intelligent (ASIC) chip and will automatically compensate for the effect of temperature, humidity and ageing. There will also be self-testing and self-cleaning functions. Ultimately a fully integrated chip may be possible. The signals from the array will be processed using artificial neural networking techniques to calibrate the nose and teach it new smells. The signal and pattern recognition routines will be developed at the University of Rome. The silicon devices will be designed at the Universities of Warwick, Neuchatel and Linkoping and fabricated at the University of Neuchatel. In the case of the cabin air-analyser, the sensing system will provide information on the quality of the air inside and outside the car which can then be used by the on-board vehicle computer to
- circulate the sir inside,
- activate an air-freshener,
- activate an air cleaning system or
- alert the driver to hazardous levels of dangerous or unpleasant fumes. For the exhaust analyser, the sensing system will enable analysis of exhaust gases using on-line equipment which is currently unavailable.

Programme(s)
