An Overview of Oxide Materials for Gas Sensors
(Institute of Electrical and Electronics Engineers Inc., 2020)
This paper presents an overview of oxide materials applied for gas sensors. This category of materials has been extensively investigated and applied in gas sensors, due to their ease of fabrication, low cost, sensitivity ...
Application of Iron Manganite Thick Films for Humidity Sensing
(IEEE Computer Society, 2019)
Iron manganite (FeMnO3) thick film samples were obtained by screen printing four layers of thick film paste on alumina substrate with test PdAg electrodes. The paste was made by adding organic vehicles to iron manganite ...
Nanocrystalline Nickel Manganite Synthesis by Sol-Gel Combustion for Flexible Temperature Sensors
(Institute of Electrical and Electronics Engineers Inc., 2020)
Nanocrystalline nickel manganite (NiMn2O4) was obtained by sol-gel combustion using glycine as fuel, followed by calcination at 800°C. X-ray diffraction (XRD) analysis confirmed the formation of a pure cubic spinel structure ...
Impedance Response of Pseudobrookite Thick Films with a Sandwich Configuration
(IEEE Computer Society, 2017)
We have investigated the impedance response of pseudobrookite thick films screen printed on alumina substrate in the temperature interval from room temperature to 350 degrees C in the frequency range 100 Hz - 1 MHz. Two ...
Impact of Microstructure on Humidity Influence on Complex Impedance of Iron Manganite
(IEEE Computer Society, 2020)
This work deals with our continued research of oxide materials for potential application in gas/humidity sensing. We have made thick film samples using iron manganite powder synthesized by a so/-gel combustion method with ...
Application of Nanocrystalline Pseudobrookite (Fe2TiO5) Thick Films for Humidity Sensing
(IEEE Computer Society, 2018)
Pseudobrookite nanocrystalline thick films were screen printed on alumina substrate with small interdigitated PdAg electrodes (width 6 mm, length 12 mm, electrode spacing 0.2 mm) and fired at 600 degrees C for 30 minutes. ...
Modeling the effect of temperature on relative humidity sensing
(IEEE, 2023)
In this work we have established a mathematical function to model the influence of the ambient temperature, relative humidity and frequency on the change of impedance. The proposed empirical description is a combination ...
Analysis of electronic properties of pseudobrookite thick films with possible application for NO gas sensing
(IEEE Computer Society, 2016)
Two pseudobrookite (PSB) containing pastes were composed of a mixture of starting nanopowders of hematite (alpha-Fe2O3) and anatase (TiO2) in the molar ratios 1: 1 (referred to as PSB-1) and 1:1.5 (referred to as PSB-1.5), ...
