The progress of magnetic sensor applied in biomedicine: A review of non‐invasive techniques and sensors

Abstract With the rapid development of sensing technology, it has attracted tremendous interests in the field of biomedicine because of its good biocompatibility, reliability, and safety. In comparison to other sensors, magnetic sensor has a broad application prospect in biomedical field due to its high sensitivity, small size, and intriguing non‐invasive detection property. The purpose of this review is to discuss the applications of magnetic sensors in the biomedical field. First, some widely used magnetic sensors are reviewed based on their working principle and characteristics. Then, the applications of magnetic sensors in biomedical field are introduced from the aspects of magnetic label‐based bioassays, detection of biological movement, and biology magnetism. Finally, the future development direction and prospect of magnetic sensors in biomedical field are prospected. This review will provide a general outlook for the applications of magnetic sensors in biomedicine.
