Recent Advances and Applications in Planar Hall Magnetoresistive Sensors

Abstract

Recent advances in nano/micro technology have resulted in the widespread adoption of magnetoresistive sensors in storage media and other applications. Magnetoresistive sensors have high performance that satisfies the demands of advanced applications that require smart sensing performance, such as the Internet of Things, mobile devices, space and aviation, as well as the smart home, environment, and health care application. In this discussion, I will talk about magnetoresistive sensors based on the planar Hall effect exhibit high sensitivity, low noise characteristics, and wide temperature range suitability for ultra-low magnetic field detection. Additionally, their simple structure makes them cost-effective, easy to fit and miniaturize, and easy to integrate, rendering them a promising sensor for various new applications.
