Electrochemical Biosensor and method of manufacture

摘要

An electrochemical biosensor (12) includes a working electrode (5) and a counter electrode (3), wherein at least a part of the working electrode (5) comprises an enzyme and is disposed between and in electrical connection with two separate conductive tracks (1,2). Other aspects of the invention provide a meter (26) for use with the biosensor (12) and a method of determining whether a fluid sample applied to the biosensor (12) has sufficiently wetted the working electrode (5).
