A chemiresistor sensor based on a cobalt(salen) metallopolymer for dissolved molecular oxygen
(2018-12-01)
A resistance detection device for dissolved molecular oxygen in aqueous solutions is prepared using a chemiresistor material as sensor platform. The chemiresistive circuit element is fashioned from a thin film of a ...
A New Possibility for Fermentation Monitoring by Electrical Driven Sensing of Ultraviolet Light and Glucose
(2020-08-01)
Industrial fermentation generates products through microbial growth associated with the consumption of substrates. The efficiency of industrial production of high commercial value microbial products such as ethanol from ...
Monitoramento térmico de máquinas elétricas utilizando sensores em fibra ótica
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia ElétricaUTFPR, 2016-06-16)
This work aims to validate the optical sensors based on fiber Bragg gratings for temperature monitoring in electrical machines (transformer and motor). The temperature parameter is of great importance in preventive maintenance ...
Grain size effect on the electrical response of SnO2 thin and thick film gas sensors
(ABM, ABC, ABPol, 2009-03-01)
Porous nano and micro crystalline tin oxide films were deposited by RF Magnetron Sputtering and doctor blade techniques, respectively. Electrical resistance and impedance spectroscopy measurements, as a function of temperature ...
Reducing the capacitance of piezoelectric film sensors
(American Institute of Physics, 2016-04)
We present a novel design for large area, wideband, polymer piezoelectric sensor with low capacitance. The large area allows better spatial resolution in applications such as photoacoustic tomography and the reduced ...
Teaching general concepts about sensors and transfer functions with a voltage divider
(2011)
This work proposes the use of a simple voltage divider circuit composed by one potentiometer and one resistor to simulate the behavior of the electrical output signal of linear and nonlinear sensors. It is a low cost way ...
Design of a low-cost residual current sensor for LVDC power distribution application
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA ELETRÔNICAUFMG, 2018)
Potential use of the veris apparent EC sensor to predict soil texture under the semi-arid conditions of central Arizona
(2009-12-01)
The operational details of the apparent electrical conductivity (ECa) sensor manufactured by Veris Technologies have been extensively documented in literature reports, but the geographical distribution of these research ...
