Developments and applications of tunneling magnetoresistance sensors

Magnetic sensors based on tunneling magnetoresistance (TMR) effect exhibit high sensitivity, small size, and low power consumption. They have gained a lot of attention potential applications in various domains. This study first introduces the development history basic principles TMR sensors. Then, comprehensive description linearization Wheatstone bridge configuration is presented. Two key performance parameters, field sensitivity noise mechanisms, are considered. Finally, emerging discussed.
