Abstract
A square wave voltammetric measurement system with an 8 × 8 array of sensing pixels is integrated within a single chip for multi point and high-speed electrochemical analysis. The sensor was designed to operate at 400 ms/frame under the condition of 20 mV and 500 Hz of step increment and square wave frequency, respectively. Peak currents from the 8 × 8 pixel array of potassium ferricyanide were obtained at the potential range from −0.5 to 0.5 V. We also obtained a small variation of the measured concentration result of all 64 pixels under the concentration range from 0.6 to 6 mM of potassium ferricyanide standard solution.
