Blood grouping using a galvanic immunoelectrode sensor
Transfusion Clinique et Biologique, 1994Traditional blood grouping techniques have been performed using either direct or indirect hemagglutination or adherence methods. Most procedures are time-consuming to perform, labor intensive and, for the most part, have subjective interpretation. An immunoelectrode system using a pair of electrodes, with either monoclonal antibody or red cell membrane

Development of a highly sensitive galvanic cell oxygen sensor
Talanta, 1995A highly sensitive galvanic cell oxygen sensor was successfully developed for determining parts per billion of oxygen in high purity gases such as nitrogen, argon, etc. The response of this improved sensor was proportional in the range of oxygen concentrations from 10.0 ppm to the detection limit. The response speed in this study was improved to within

Accurate voltage-to-frequency sensor with galvanic isolation and bandwidth of 375kHz
2020 IEEE Industry Applications Society Annual Meeting, 2020High-bandwidth low-cost MV voltage sensors with appropriate isolation are required in MV power electronic converters for utility and industrial applications. It is especially critical in low-inertia converters (reduced passives) due to the existence of fast dynamics with reduced storage elements (dc-link, filters etc.).

Paper-Based Sensor for Electrochemical Detection of Silver Nanoparticle Labels by Galvanic Exchange
ACS Sensors, 2016 Here we report a three-dimensional paper fluidic device configured for electrochemical detection of biomolecules labeled with silver nanoparticles (AgNPs). This new sensor, which we call a NoSlip, represents a major improvement of our previously reported

A galvanic sensor for monitoring corrosion of steel in carbonated concrete
Magazine of Concrete Research, 1991The construction and operation are described of a galvanic sensor which responds to changes in the corrosion intensity of mild steel in carbonated mortars or concretes. The sensor is simple to construct and operate; it is robust and has potential for development as an inexpensive method of long-term continuous nondestructive corrosion monitoring of ...

The status of chemical sensors for hot-dip galvanization
JOM, 1996Alloying elements are added to the zinc used in the hot-dip galvanization of sheet steel to control the properties and appearance of the resulting coating. For example, aluminum is added to improve the corrosion resistance and adherence of the coating.

Multilayer Galvanic Cell for Next Generation Corrosion Sensors
CORROSION 2000, 2000Abstract We describe an improved galvanic corrosion sensor element design that uses a multilayer structure to separate the anode and cathode. The improved design offers significant advantages in sensitivity and lifetime over conventional thin-film galvanic sensors.

Galvanic-Type Electrochemical Sensor for Determining the Content of Hydrohalogens in the Air
Sensors and Actuators B: Chemical, 2003Abstract A galvanic-type amperometric sensor based on manganese dioxide gas-diffusion electrodes has been created for determining the concentration of hydrohalogens (HCl, HBr, HF) in the air. The sensor works on the principle of solid phase reduction of manganese dioxide at the indicator electrode with simultaneous absorption of hydrohalogens from ...

Novel Solid State Galvanic Cell Gas Sensors
1989Solid electrolytes transduce the ratio of the activities of the electroactive component at both electrodes directly into an electrical voltage. Oxygen ion conductors such as zirconia are commercially successfully employed on this basis as sensors for oxygen partial pressures in automobile exhaust systems, in molten steel and for food packing.
