24 Αυγ 2016 · The chemical sensor is an analyzer that responds to a particular analyte in a selective and reversible way and transforms input chemical quantity, ranging from the concentration of a specific sample component to a total composition analysis, into an analytically electrical signal [1, 2], as depicted in Figure 1.
Potentiometric sensors are based on a chemical reaction (a redox reaction) in equilibrium. Amperometric sensors are based on a running redox reaction. Some authors define a third group of electrochemical sensors, namely the conductometric or impedimetric sensors.
10 Οκτ 2017 · Teaching about sensors requires references to analytical definitions, and a discussion of sensor principles combined with detection principles, the process of sensor interaction with the analyte, and data treatment.
A chemical sensor is a device that transforms chemical information, ranging from concentration of a specific sample component to total composition analysis, into an analytically useful signal. This very general definition does not really agree with the popular view on sensors in general.
9 Ιαν 2019 · New generations of established sensors, such as metal oxides, are being pushed to new limits by employing nanostructured materials. One of the promises of chemical sensors is that they can be widely deployed to provide comprehensive spatial and temporal analysis of a particular problem.
