Abstract :
We have designed and fabricated a 2×4 electrochemical image sensor with CMOS signal processing circuits integrated on a single chip. Using a well-studied ferricyanide solution, a clear cyclic voltammetry curve was obtained from each working electrode of the array sensor. The external components used include a data generator and a data recorder. This sensor chip is an early prototype of a fully integrated system of a fast-scan electrochemical image sensor that uses microelectrodes.
