In a Galvanic sensor, the cathode is silver and the anode is zinc. The two materials are dissimilar enough to self-polarize and reduce oxygen molecules without an applied voltage. This is similar to how a battery works. The system uses a meter to read the electrical signal and the signal is proportional to the amount of oxygen passing through the membrane.
The Galvanic sensor contains silver and zinc. These two materials are different enough to self-polarize without added voltage. This allows them to be used immediately instead of waiting on the anode and cathode to polarize.
The steady-state sensor reduces oxygen, meaning it is flow dependent. The sensors require stirring or sample movement to produce accurate readings.

The Charles River used to be a swimming hotspot for Cambridge and Boston residents.
Decades of industrial pollution and nutrient runoff have degraded water quality and eliminated public swimming in the Lower Charles, but a movement is afoot to get Boston and Cambridge back in the water. One step toward the goal of a safely swimmable river—without the need to obtain a permit, as is now necessary—is detecting and managing the harmful algal blooms that appear on the river.
An experimental floating wetland and new research and analysis of water quality data that shows a possible effective detection system for algal blooms on the Charles River are two new steps toward the goal of safe, accessible swimming.Read More
The Gulf Stream, the massive western boundary current off the east coast of North America, moves water from the Gulf of Mexico north and west across the Atlantic Ocean. There’s a lot of energy in that much moving water and researchers are trying to put it to use.
Although the Gulf Stream’s path shifts (researchers say it acts like a wiggling garden hose), in a couple of spots, it stays relatively stable. At one such spot off the coast of Cape Hatteras, North Carolina, researchers have dropped moorings and research instruments to study the current with the eventual goal of harnessing it for renewable energy.Read More
