What is a Chemical Sensor?

A chemical sensor is a device that transforms chemical information—such as the concentration of a specific substance—into an electrical, optical, or mechanical signal. The core functionality of a chemical sensor is to identify and quantify chemical species in a sample.

Basic Components:

• Recognition Element (Receptor): Selectively interacts with the target analyte (e.g., gas molecules, ions, or organic compounds).

• Transducer: Converts the interaction into a measurable signal.

• Signal Processor: Analyzes and outputs the data.
