Description

Technical Field

[0001] This utility model relates to the field of electrochemical sensor technology, specifically a novel electrochemical sensor. Background Technology

[0002] As is well known, in the field of existing electrochemical sensing technology, sensors are key devices for detecting and analyzing electrochemical reactions in solutions, and their performance directly affects the accuracy and reliability of measurement results. Although traditional electrochemical sensors can meet basic detection needs to a certain extent, they often have many limitations when facing complex and ever-changing detection environments.

[0003] Specifically, the electrode detection head position of traditional electrochemical sensors is usually fixed and cannot be flexibly adjusted according to actual needs. This makes it difficult to optimize the contact area and position between the electrode and the reactants in the solution during the detection process, thus affecting the transmission efficiency and measurement accuracy of electrochemical signals. Especially in situations where precise control of the electrode position is required to improve measurement sensitivity, this not only affects the accuracy of electrochemical measurements but also limits the application of the sensor in complex solution environments.
