摘要

磁性微型和纳米传感器应用广泛,如导航、汽车、智能手机和健康监测。基于众所周知的磁感应、霍尔效应、隧道磁阻和巨磁阻等物理效应,它们可用于测量位置、流量、压力和其他物理特性。在生物医学和医疗保健领域,这些微型传感器既可以集成到服装和其他可穿戴设备中,也可以通过无源胶囊或有源微型机器人导入体内或植入体内,这通常需要生物功能化和避免使用对细胞有毒的材料。本综述介绍了可应用于这些传感器的物理效应,并讨论了最近为医疗保健应用开发的微型和纳米传感器。

Magnetic Micro and Nano Sensors for Continuous Health Monitoring
Magnetic micro and nano sensors can be used in a broad variety of applications, e.g., for navigation, automotives, smartphones and also for health monitoring. Based on physical effects such as the well-known magnetic induction, the Hall effect, tunnel magnetoresistance and giant magnetoresistance, they can be used to measure positions, flow, pressure and other physical properties. In biomedicine and healthcare, these miniaturized sensors can be either integrated into garments and other wearables, be directed through the body by passive capsules or active micro-robots or be implanted, which usually necessitates bio-functionalization and avoiding cell-toxic materials. This review describes the physical effects that can be applied in these sensors and discusses the most recent micro and nano sensors developed for healthcare applications.
