TiO₂ (001) Resistive Gas Sensor Diagram - Structure and Operation #1581775 (License: Personal Use)

This diagram depicts a resistive gas sensor built on a TiO₂ (001) single-crystal substrate, where two gold electrodes contact the semiconductor surface to measure resistance changes upon gas exposure. The circuit includes a series sensing resistor Rs and a load resistor R, with VR measured across R to detect analyte-induced conductivity shifts. The green IO₂ region indicates the active sensing layer or surface adsorption site.

Used in technical documentation, academic papers, or educational content about chemiresistive sensors; targets engineers, materials scientists, and students seeking to understand TiO₂-based gas detection mechanisms.
