Magnetoresistive Sensors

Magnetoresistive sensors are electronic devices that measure changes in electrical resistance in response to an applied magnetic field. These sensors utilize the magnetoresistive effect, where the electrical resistance of a material changes with variations in the surrounding magnetic field. Common types include anisotropic magnetoresistance (AMR), giant magnetoresistance (GMR), and tunnel magnetoresistance (TMR). By detecting subtle magnetic field changes, magnetoresistive sensors find applications in various technologies, such as magnetic field sensing, data storage, and position detection in devices like compasses and automotive sensors. Their sensitivity, compact size, and low power consumption make them essential in modern electronic systems.
