We have reviewed the humidity sensors based on ceramic materials. We first discuss the
operating principle of ceramic humidity sensors. This is followed by a section on the …

In this paper, we present a comparative study of humidity sensing characteristics of three
novel sensing materials, keratin wool as matrix and its composites (keratin/1% graphene …

Recently, cellulose has been re-discovered as a smart material that can be used as sensor
and actuator materials, which is termed as electro-active paper. In this work we demonstrate …

Mesoporous LaFeO3 with high surface area and pore volume was prepared through a
nanocasting route by using mesoporous silica SBA-15 as a hard template. The structure and …

We report on the effects of plasma treatment and humidity on the electrical conductivities of
Ti3C2 MXene thin films. The latter–spincoated from a colloidal solution produced by LiF/HCl …

Composites of mesoporous silica SBA-15 and MgO/KCl were prepared by a simple grind
method following a heat-treatment process. Their structures were characterized by X-ray …

Hierarchical tin (Sn)-doped zinc-oxide (ZnO) nanorod arrays (SZO) were deposited onto Al-
doped ZnO-coated glass substrate by using a sonicated sol–gel immersion method for …

This paper reports a simple and rapid microwave-assisted method for synthesizing cerium
oxide (CeO 2) nanoparticles for the fabrication of high-performance humidity sensors. The …

Capturing environmental stimuli is an essential aspect of electronic skin applications in
robotics and prosthetics. Sensors made of temperature-and humidity-responsive hydrogel …

CeO 2 is a good humidity sensitive material, which has been widely investigated by using
direct current (dc) analysis method. In this paper, we used the complex impedance analysis …
