Electrochemical Sensors

A sensor is a device that reacts to physical stimuli like heat, light, sound, pressure, magnetic, or movement and communicates the ensuing electrical impulse to measure any changes in the component material's intrinsic properties. The Latin verb sentire, which means to feel, is the source of the term sensor. Sensors have the ability to perceive their immediate surroundings and define a coupling relationship. Particularly among chemical sensors, electrochemical sensors employ an electrode as a transducer element when an analyte is present. Physical, chemical, or biological characteristics may all be detected by modern electrochemical sensors using a variety of attributes. Examples include sensors for monitoring the environment, for health and instrumentation, and for sensors connected to machines like cars, aircraft, mobile phones, and technological media. Modern sensing systems have profited in recent decades from advancements in microelectronic and microengineering, primarily through the manufacture of progressively smaller sensors with greater sensitivity and selectivity as well as cheaper production and maintenance costs.
