Humidity-sensing studies of cerium oxide nanoparticles synthesized by non-isothermal precipitation

- CeO2 nanoparticles prepared by a simple and low cost non-isothermal precipitation.
- High-performance humidity sensor has been fabricated using CeO2 nanoparticles.
- Systematic characterization of the sensor.
- The sensor exhibits a fast response (∼2-3 s) and a quick recovery (∼9-10 s).
