A new automotive air/fuel sensor based on TiO2-doped Nb2O5 thin film by ion-beam-enhanced deposition

Zhu, J. / Ren, C. / Chen, G. / Yu, C. / Wu, J. / Mu, H.

This paper describes the preparation of a TiO2-doped Nb2O5 thin film using the ion-beam-enhanced deposition technique and the developement of a new automobile air/fuel sensor with an additionally integrated platinum temperature sensor and a Pt heater. The resistive jump at the stoichiometric point in the characteristic curve is three orders of magnitude. The response time of the sensor is almost identical with that of the ZrO2 oxygen sensor. The performance of the sensor becomes stable after seven measurement periods. Preliminary results indicate that this sensor exhibits attractive performance and the potential to monitor the lambda-value for automobile exhaust gas.
