Mechanical stress and stress compensation in Hall sensors

Silicon magnetic sensors based on the Hall effect have proven to be an excellent sensor choice for many applications, such as position sensing, gear-tooth sensing, contact-less switching and linear sensing. Although a sensor can be trimmed over temperature before it is shipped to the customer, little can be done about the sensitivity's stability once the sensor has been installed in its final application.
The goal of this project is to propose and implement mechanisms to stabilize the Hall sensor's sensitivity through the use of mechanical stress feedback and magnetic feedback.
