👉 A sensor fluid, also known as a sensing medium or a sensing liquid, is a specialized material used in sensors to detect and measure various physical, chemical, or biological parameters. Typically composed of a liquid that contains dissolved or suspended sensing agents, these fluids interact with the environment they are designed to monitor, such as gases, ions, or biomolecules. When the target analyte interacts with the sensing agents, it causes a change in properties like electrical conductivity, optical characteristics, or mass, which the sensor can then convert into a measurable signal. This interaction enables precise and sensitive detection, making sensor fluids crucial components in a wide array of applications, from environmental monitoring to medical diagnostics.
