A one-day meeting was held by the Instrument Science and Technology (ISAT) group on November 6, 2001, entitled 'New generation automotive sensors: The challenge of hostile environments'. The nine presentations covered topics ranging from the development of sensing devices and underlying technologies to sensor testing, protection and packaging. A paper from TWI Ltd., 'Packaging for harsh environments', focused largely on thermal effects but also highlighted some of the other potentially detrimental factors that automotive sensors need to withstand, e.g. moisture, salt, fuel, brake fluid, strong detergents (in car washes), exhaust gases and all manner of mechanical stresses. 'Fit for purpose packaging methods for next generation automotive sensors' was the title of a presentation by a speaker from Micro Circuit Engineering. This focused very much on some of the specific packaging requirements of advanced, micromachined sensors such as silicon gyroscopes and accelerometers. The test and condition monitoring of MEMS devices was the topic of a presentation by a speaker from Lancaster University. Various MEMS devices were described, including pressure and acceleration sensors, micro-motors and micro-mirrors. The sensor requirements of the Foresight Vehicle Programme were discussed by a speaker from TWR. This is a UK government programme concerned with future vehicles and transport systems and attempts to generate a vision of these up to the year 2020. It comprises several themes, including sensors. A collaborative project involving BAe Systems and the University of Nottingham was the topic of a presentation by a speaker from the latter organisation and concerned multi-axis gyroscopes or 'rate' sensors based on the vibrating ring principle. In contrast to the above, research at Cranfield University, in conjunction with the University of Nottingham, AEA Technology, the DETR and Transense Technology, concerns the development of a vibrational gyroscope which uses thin film surface acoustic wave (SAW) sensors. A presentation by a Speaker from the University of Middlesex discussed new developments in automotive oxygen sensors. Solid-electrolyte oxygen ('lambda') sensors, based on zirconium oxide, are used on vehicles fitted with catalytic converters to hold the air/fuel ratio at, or dose to, the stoichiometric point and thus optimise the combustion efficiency, minimise noxious exhaust emissions and protect the catalyst. A speaker from TRW Automotive discussed new driver assistance systems, including adaptive cruise control (ACC) and lane detection/departure warning systems. Imaging using IR was the theme of a paper from IRISYS, a UK manufacturer of low cost IR sensing technologies. Using novel pyroelectric ceramic sensing technology, the company has developed inexpensive imaging systems. Overall, this event gave a broad and reasonably well balanced overview of development in automotive sensors. In particular, it highlighted the critical need to achieve high performance at very low costs, combined with protection against an often extremely harsh operating environment.
