摘要： A magnetoresistive magnetic imaging sensor for identifying a magnetic image comprises a PCB (1) and several magnetoresistive sensor chips (2), wherein the several magnetoresistive sensor chips (2) are located on the PCB (1), and the PCB (1) is perpendicular or parallel to the magnetic image detection surface (3). It has a lateral detection mode and front detection mode, In the lateral detection mode, each side face (2(1)) of the several magnetoresistive sensor chips (2) is parallel or coplanar with the side (1(1)) of the PCB(1), and parallel to the magnetic image detection surface. The several magnetoresistive sensor chips (2) have the same magnetic sensing direction. In the lateral detection mode, the adjacent magnetoresistive sensor chips (2) are stacked, while in the front detection mode, the adjacent magnetoresistive sensor chips (2) are arranged in a staggered manner, in order to achieve continuity of the detection area in the magnetic image detection surface. The magnetoresistive magnetic imaging sensor may also comprise a permanent magnet assembly and a housing. The sensor has several advantages, including continuity across the detection area, good signal reproduction, high sensitivity, and low power consumption.

摘要： The present invention discloses a magnetic field sensing device that utilizes a single coil for calibrating the response of the sensor to compensate for temperature dependent sensitivity drift and also for resetting the magnetic field sensor in order to eliminate hysteresis. The single coil configuration is advantageous since it reduces the size of the sensor chip by decreasing the number of contact pads on the chip and also because it wastes less space, which permits an increase in the density of the magnetoresistive elements on the sensor chip.

摘要： The present invention discloses a MTJ triaxial magnetic field sensor, comprising an X-axis bridge sensor that has a sensing direction along an X-axis, a Y-axis bridge sensor that has a sensing direction along a Y-axis, a Z-axis sensor that has a sensing direction along a Z-axis, and an ASIC chip connected with and matched to the X-axis, Y-axis, and Z-axis sensor chips. The Z-axis sensor includes a substrate and MTJ magnetoresistive elements deposited on the substrate. The Z axis magnetic field sensor is attached to the ASIC chip along an attachment edge, and an angle is formed between the sensor side of the Z axis magnetic field sensor and the adjacent attachment edge. The attachment edge angle is an acute angle or an obtuse angle. The resulting X, Y, and Z axes are mutually orthogonal. The above design provides a highly integrated sensor with high sensitivity, low power consumption, good linearity, wide dynamic range, excellent thermal stability, and low noise.

摘要： Disclosed are a magnetic bar code chip and a reading method thereof. The magnetic bar code chip comprises binary information bits formed by N rows and M columns of permanent magnet bars and/or null bits, and information identification bits that are peripheral to the binary information bits. The information identification bits are composed of permanent magnet bar identifiers and used for representing a position and a state of the magnetic bar code chip. The permanent magnet bars and the null bits represent 1 and 0 or 0 and 1 respectively. During reading, a strong magnetic field in a row direction of the binary information bits of the magnetic bar code chip is firstly used to set a magnetization direction of the permanent magnet bars, and then a magnetic bar code reader such as a multi-channel magnetic field gradient sensor, a magneto-optical microscope, a magnetic field monitor, a scanning magnetoresistivemicroscope and the like is used to convert magnetic field distribution information generated by the permanent magnet bars on the magnetic bar code chip into the binary information bits and information identification bits respectively, thus implementing reading on a reading result of the magnetic bar code chip.
