Homogeneous ceria nanoparticle slurries were chemically derived.
Samples were prepared as tape-casted thin-films on conducting glass and pressed pellets.
Solid-state impedance spectroscopy (SS-IS) was employed under controlled relative humidity (30%-85%) across wide temperature and frequency ranges.

Main Results:

Structural analysis confirmed monophasic crystalline ceria with low surface roughness.
Increased relative humidity led to higher DC conductivity in ceria, similar to temperature effects.
Ceria thin-films exhibited more sensitive and reversible humidity detection compared to pellet forms, especially in surface-mode measurements.

Conclusions:

Chemically derived ceria nanoparticles, particularly in thin-film configurations, show significant potential as humidity sensing materials.
Thin-film thickness and measurement configuration (surface vs. cross-section) critically influence electrical properties and humidity sensitivity.
The reversible moisture sensitivity of thin-film ceria makes it a viable candidate for practical humidity sensing applications.
