In addition, by the magnetic flux generated from the tag medium for detecting the
In other words, the magnetic properties of the tag media are converted into electrical output through the sensing device.
In addition, differentiation-type magneto-resistive (MR) and GMR (Giant MR) use the magnetoresistance of the magnetic properties of the magnetic medium as a sensor element of the sensing device.
In other words, an element whose resistance changes according to the change of magnetic flux (this is called an MR element) is used. Such an MR element uses a large magnetoresistive MR (GMR) element having a large magnetoresistance ratio. The magnetoresistance phenomenon is observed in most metal thin films. The most important point is that the resistance of the metal film depends on the direction of magnetization. Specifically, if the direction of the current is the same as the direction of magnetization, the resistance is large, and if the direction of the current and the direction of the magnetization is perpendicular, the resistance is small.
This change in resistance occurs because scattering of electrons at the magnetic nonmagnetic interface depends on the direction of magnetization.
And the characteristic of MR technology is to measure the magnetic flux directly. Therefore, the output is almost independent of the linear velocity of the detection tag inserted in the paper, and since the power is used as the active device, the output increases as the sensing current increases.
In addition, the differential type MI and GMI have an impedance when the high-frequency current is energized by the ferromagnetic material depending on the external magnetic field.
That is, when a high frequency alternating current is supplied to the soft magnetic material, the impedance is changed by the skin effect of the magnetic material.
Therefore, when the magnitude of the voltage is measured at both ends of the magnetic material while energizing a high frequency constant current, it changes according to a magnetic field applied from the outside. The magnetic field can be detected by converting the voltage into a magnetic field. An element that detects a magnetic field using such a phenomenon is called a magneto-impedance (MI) effect element.
Here, the magnetic impedance effect refers to an electromagnetic phenomenon in which the impedance is changed at high sensitivity by an external magnetic field when a high frequency current or a pulse current flows by generating an epidermal effect on the magnetic material.
In addition, since the MI sensor performs a high frequency modulation operation, the response speed is remarkably high, and the conduction current is very low, which may be used in combination with a semiconductor device.
In addition, the differential type EM (Electro Magnetic) and AM (Acoustic Magnetic) are technologies using frequency change characteristics according to the change of the magnetic field properties, where the EM (electro magnetic) is a harmonic sensor and magneto elastic (ME). ) It is divided into two kinds of sensors.
Harmonic sensors mainly use Co-based (A, B, Si, etc.) amorphous soft magnetic alloy amorphous ribbons, which generate a change in magnetic properties clearly distinguished at specific frequencies through an appropriate heat treatment process. In the specific magnetic field region, the characteristic that changes according to the time change of the external magnetic field is to detect the electrical change value in the pick-up coil.
In this principle, when the paper equipped with the harmonic sensor passes through the detection system of the present invention, it is detected and applied to discriminating whether or not the

That is, the EM method detects and detects harmonics generated by alternating alternating magnetic fields in the monitoring area when soft magnetic material (metal) is placed in the alternating magnetic field.
