Abstract: The triaxial magnetometer is a vector magnetic field sensor widely used in various fields. Due to limitations in manufacturing and installation processes, a ...

Abstract: In this research, we present a hermetically sealed integrated diamond magnetometer for vector magnetometry. The diamond chip, fabricated using standard microfabrication processes, has a ...

I’m already loving this device, and I haven’t even touched one. Arduino announced it has collaborated with M5Stack to develop the new compact and powerful Nesso N1 IoT development kit. This system ...

A SELF-OSCILLATING rubidium vapour magnetometer, in which measurements of the total field magnitude are obtained by counting the frequency of self-oscillation in the radio-frequency range, has been ...

The central mass of a brain tumour is relatively straightforward for surgeons to remove — but identifying the full extent of tissue to safely remove presents a bigger challenge, as it may involve ...

从古老的指南针到现代的智能手机，磁力计 (magnetometer)一直默默地影响着我们感知与导航世界的方式。现在，让我们一同探索这些磁场探测设备背后的基本原理。 磁场无所不在，却无法被肉眼直接看见。磁力计能将这些隐藏的力量转换为可测量的信号，从导航系统到消费电子产品，皆依赖它们来工作。接下来，让我们深入探讨，使一颗简单传感器能够把无形力量转化为可用数据的核心原理。
