SYSTEM FOR SIGNAL DETECTION OF SPECIMEN USING MAGNETIC RESISTANCE SENSOR AND DETECTING METHOD OF THE SAME

摘要

PURPOSE: A signal detection system of a specimen and a detecting method thereof are provided to maximize the sensitivity of a sensor by applying the direction of a magnetic field, which is applied to a magnetic resistor sensor, in an X and a Y axis direction. CONSTITUTION: A specimen fixing part(120) fixes a specimen. An external magnetic field providing part(110) applies magnetic field in the outside of the specimen. A magnetic resistor sensor(130) senses a magnetic signal about the specimen which is combined with the magnetic component. The magnetic resistor sensor divides the signal into an electric component and analyzes it.
