Definition of Sensor

“... device, that responds to a physical (or chemical) stimulus (heat, light, sound, pressure, motion, magnetism...) and transmits a resulting impulse (as for measurement or operating a control).”

Biochemical Sensor

“... A device incorporating a biochemical sensing element either intimately connected to or integrated within a transducer”.
Also, A Self-contained integrated device that is capable of providing specific qualitative or semi-quantitative analytical information using a biological recognition element which is in direct-spatial contact with a transduction element. (IUPAC,1998)
                                                     1)Biosensor ≠ Bioanalytical System
2)An Enzyme Electrode is a Biosensor

Current Definition of Biosensors

A sensor that integrates a biological element with a physiochemical transducer to produce an electronic signal proportional to a single analyte which is then conveyed to a detector.
