This technology is a simple metal electrode that reacts to the presence of hydrogen ions, for use in measuring the pH of a fluid.
pH sensors are sensors that measure, the acidity or alkalinity of a fluid. They can measure pH in a variety of ways, one of which is through use of an electrode. The electrode is placed within the fluid, and the properties of the electrode will cause a voltage to occur based on the pH levels in the fluid.
The most common type of electrode used in pH sensors is the glass electrode, which uses a membrane of glass that is sensitive to Hydrogen ions (which are responsible for changes in pH). But glass electrodes tend to be fragile, particularly when miniaturized.
This technology provides an alternative metal-based pH electrode that has no glass membrane and is, therefore, more robust than alternative electrodes.
