Electrochemical sensor

摘要

An electrochemical sensor for sensing a target substance is disclosed. In one example, the sensor discloses an electrolyte matrix, wherein the matrix reposits an electrolyte; a working electrode coupled to the electrolyte matrix at a first location; a counter electrode coupled to the electrolyte matrix at a second location; an electrical circuit, coupled to the working electrode and the counter electrode, and capable of generating an output signal in response to an electrical current which flows between the working electrode and the counter electrode in response to a presence of the target substance.
