Advances in the Microfabrication of Electrochemical Sensors and Systems

Technologies to microfabricate electrochemical sensors and systems are rapidly advancing and will surely have an impact on critical fields such as medicine, environment, and information processing. It is a good opportunity to review the state of the art and trends in the technologies developed in this field during the last two decades of the 20th century and prepare for the coming decades. Here, developed electrochemical microsensors and microsystems will be reviewed in terms of techniques and performance along with the problems left as issues for the next century.
