ELECTRICAL DEVICES WITH ENHANCED ELECTROCHEMICAL ACTIVITY AND MANUFACTURING METHODS THEREOF

摘要

In some aspects, a device is provided having a member with a region of enhanced electrochemical activity. In one aspect, a sensor of enhanced electrochemical activity is provided for detecting an analyte concentration level in a bio-fluid sample. The sensor may include a sensor member of a semiconductor material wherein the sensor member has a surface region of enhanced electrochemical activity. In other aspects, the member may be made of semiconducting foam having a surface region of enhanced electrochemical activity. In some embodiments, the region may be thermally-induced. Manufacturing methods and apparatus are also provided, as are numerous other aspects.
