Abstract
This paper presents a microcantilever humidity sensor based on chitosan (CS)/montmorillonite (MMT) composite. At room temperature, the sensor exhibits remarkable performance, including high sensitivity (508 nm/%RH), minimal humidity hysteresis (<2.5 % RH), rapid response and recovery times (24 s/25 s), and long-term stability across a relative humidity range of 10 %–85 %. The morphology and structure of the CS/MMT composite were analyzed using scanning electron microscopy (SEM), X-ray diffraction (XRD), and contact angle measurements. Its excellent moisture sensitivity is attributed to the composite’s ability to retain the film-forming properties of CS while increasing the specific surface area and hydrophilicity through MMT incorporation. Therefore, the CS/MMT composite demonstrates significant potential as a moisture-sensitive material.
