Humidity sensor based on iron oxide nanoparticles supported sepiolite.

摘要

Humidity sensor based on iron oxide nanoparticles supported sepiolite.; This patent relates to a system based on an active powder consisting of nanoparticles of iron oxide supported on sepiolite microfibers humidity sensor. Depending on the content of said nanoparticles (5-50%) the sensor can work in a wide range of RH (0-80%) with a reproducible rapid response (10 s) and absent from hysteresis phenomena. Following that nanoparticles of iron oxide are embedded in the microfibers sepiolite is resistant environmental sensor.
