An Improved Clark-Type Galvanic Sensor for Dissolved Oxygen
Sensors and Actuators B: Chemical, 1996 A novel Clark-type galvanic oxygen sensor has been fabricated, in which the indicator electrode is made from an industrially produced NiCu alloy containing ≃ 30% Ni. The exposed are of the tubular-shaped indicator electrode is about 10 cm2. The anodeis prepared from cadmium. The sensor is filled with 6 M aqueous KOH solution.

Setup of Galvanic Sensors for the Monitoring of Gilded Bronzes [PDF]
Sensors, 2014 Traditional electrochemical techniques, such as linear polarization resistance (Rp), and electrochemical impedance spectroscopy (EIS), cannot be applied to gilded bronzes, as it may not be possible to interpret the results obtained due to the bimetallic nature of the studied material.

Galvanic Sensor for Determination of Hydrogen Sulfide
Electroanalysis, 1994AbstractA galvanic cell for trace determination of hydrogen sulfide in gases is presented. The cell covers the range from 30 ppb to some hundred ppm. It is characterized by simple construction. The use of ferricyanide/ferrocyanide ions as a redox mediator system ensures very low cross sensitivity. The sensor is well‐suited for mobile use.

Galvanic etching for sensor fabrication
Journal of Micromechanics and Microengineering, 2000This paper describes the application of a novel etch-stop technique, based on galvanic element formation, to the fabrication of micromechanical sensors. The theory of operation in tetramethyl ammonium hydroxide (TMAH) and hydrofluoric acid (HF) solutions is discussed, together with the main limitations. A number of devices are presented.

Sensors Based on Galvanic Cell Generated Electrochemiluminescence and Its Application
Analytica Chimica Acta, 2006In this paper, a novel electrochemiluminescence (ECL) imaging sensor array was developed for determination of hydrogen peroxide (H2O2), which was based on Cu/Zn alloy galvanic cell generated ECL. In alkaline solution, Cu/Zn galvanic cell was formed because of corrosion effect, the galvanic cell could supply stable potential for ECL generation of ...

Design of Portable Galvanic Skin Response Sensor for Pain Sensor
2020 International Conference on Smart Technology and Applications (ICoSTA), 2020This paper describes the design of a portable galvanic skin response (GSR) sensor for pain sensors. GSR sensors can measure electricity change in the skin. The signal results obtained are used to collect autonomic nerve responses as a function parameter of sweat ties.

Failure Prediction for a Galvanic Oxygen Sensor
Sensors and Actuators B: Chemical, 2001Abstract Electrochemical oxygen sensors are widely used for industrial hygiene applications to monitor potentially dangerous conditions due to oxygen deficiency or excess. Oxygen sensors of the galvanic type operate by consumption of an internal, easily oxidizable anode.

APPLICATIONS OF SOLID ELECTROLYTES IN GALVANIC SENSORS
1989The concepts and theoretical origins of conduction domains for solid electrolytes and electrode polarization are outlined briefly. The point electrode made of the ' solid electrolyte material is useful for deflecting the semipermeability flux away from the electrode.
