Bias-free Magnetoresistive Sensors

Summary

In smart systems, sensors play an important role because they form the link between mechanical and electronic systems. Magnetic sensors are widely used to measure mechanical quantities because they allow contact-less and, therefore, wear-free measurements. In particular, magnetoresistive sensors can be easily integrated with the semiconductor technology.

The goal is to develop novel magnetoresistive sensors with better performance as compared to those currently employed by the industry. The sensors we propose here are solid–state magnetoresistive devices but their magnetic configuration is different from the currently used spin-valve. This helps overcome the two major limitations of the current magnetoresistive sensors: reliability at high temperatures and necessity of a bias magnet.
