A novel asymmetric ratio conductance sensor for electrochemistry

We have designed and fabricated thin film asymmetric electrochemical sensor for monitoring of small differences of concentration. The concentration difference measurements are based on the combination of two couples of two cells with unequal conductance values and identical concentration coefficient of conductance. Developed asymmetric ratio conductance method for measuring of concentration differences with high accuracy and adjustable sensitivity seems to be very promising for application in electrochemical sensors used in medical, food and environmental analyses.
