Cylindrical metal oxide gas sensor on a Pyrex tube

A thin film metal oxide gas sensor has been grown of the surface of a cylindrical Pyrex tube.

Reactive Pulsed Laser Deposition was used to depotit the thin film (Fig. 1).

A home-made cheap ceramic oven has been used to heat the thin film sensor to temperatures up to 500C (Fig.2).

The oven was heated with DC current and the tempeerature was monitored with an embedded thermocouple.
