“…The current is generated as a result of the reaction flow through the WE and AE (Pt electrode), while the potential of the WE is controlled in relation to the RE (saturated calomel, Ag/AgCl), which has a constant and reproducible potential. 19,20 More importantly, since the reactions are detected only in proximity to the WE surface, the electrode plays a significant role in the overall performance of the sensor. This EC sensor comprises an EC transducing element denoted as an EC transducer and a recognition layer.…”
