Magnetic field sensors are an integral part of many industrial and biomedical applications, and their utilization continues to grow at a high rate. The development is driven both by new use cases and demand like internet of things as well as by new technologies and capabilities like flexible and stretchable devices. Magnetic field sensors exploit different physical principles for their operation, resulting in different specifications with respect to sensitivity, linearity, field range, power consumption, costs etc. In this review, we will focus on solid state magnetic field sensors that enable miniaturization and are suitable for integrated approaches to satisfy the needs of growing application areas like biosensors, ubiquitous sensor networks, wearables, smart things etc. Such applications require a high sensitivity, low power consumption, flexible substrates and miniaturization. Hence, the sensor types covered in this review are Hall Effect, Giant Magnetoresistance, Tunnel Magnetoresistance, Anisotropic Magnetoresistance and Giant Magnetoimpedance.

磁场传感器是许多工业和生物医学应用不可或缺的一部分，其利用率持续高速增长。这一发展既受到物联网等新用例和需求的推动，也受到灵活和可拉伸设备等新技术和新能力的推动。磁场传感器利用不同的物理原理进行操作，导致在灵敏度、线性度、磁场范围、功耗、成本等方面的规格不同。在本次审查中，我们将重点介绍可实现小型化且适用的固态磁场传感器用于集成方法以满足不断增长的应用领域的需求，如生物传感器、无处不在的传感器网络、可穿戴设备、智能事物等。此类应用需要高灵敏度、低功耗、柔性基板和小型化。因此，本评论中涵盖的传感器类型是霍尔效应、巨磁阻、隧道磁阻、各向异性磁阻和巨磁阻。
