Fabrication of a Portable Electrochemical Sensor System

Abstract

A compact electrochemical sensor system was constructed by using basic electrical and electronic circuit design and a microcomputer for the control. The measurement accuracy was almost the same as the one obtained with a commercially available potentiostat which is a typical electrochemical measurement equipment. The proposed system implements a function that displays the measurement results immediately using Processing a programming language for visual design. The low manufacturing cost is also one of the attractive features of this system. In other words, this system is readily available and compact so that it can be used anywhere. This suggests that such a system should be highly useful in various industrial fields.
