In what context are electrochemical sensors mainly utilized?

Electrochemical sensors are primarily utilized for monitoring environmental conditions and biochemical substances due to their ability to detect and quantify various chemical species through redox reactions. These sensors can measure concentrations of gases, ions, and biomolecules in different environments, making them incredibly valuable in applications such as environmental monitoring (e.g., detecting pollutants in air or water) and healthcare (e.g., measuring glucose levels in blood).

Their operation often involves electrochemical reactions occurring at an electrode, where the current generated is proportional to the concentration of the analyte. This sensitivity and specificity make electrochemical sensors ideal for real-time monitoring of changing conditions or concentrations, which is critical in fields such as environmental science, food safety, and medical diagnostics.

In contrast, other contexts such as building electronic circuits, conducting thermal analysis, or assessing mechanical properties do not leverage the unique characteristics of electrochemical sensors. These areas typically employ different techniques and instrumentation, highlighting the special role that electrochemical sensors play in the analysis of chemical and biological substances.
