论文摘要
利用量子效应的磁场传感器表明,它们可以在敏感性方面超越经典传感器,从而在将来能够在诸如脑机界面(例如脑机界面)中进行一系列新型应用。钻石中带负电荷的氮态(NV)中心已成为一个有希望的高灵敏度平台,用于在室温下测量磁场。将这项技术从实验室设置转移到产品和应用中,传感器的总尺寸,整体功耗以及成本需要降低和优化。在这里,我们演示了一个基于纤维的NV磁力计,其完整集成了所有功能组件,而无需使用任何笨重的实验室设备。该集成的原型允许对磁场的灵敏度为344 pt/ sqrthz。
Magnetic field sensors that exploit quantum effects have shown that they can outperform classical sensors in terms of sensitivity enabling a range of novel applications in future, such as a brain machine interface. Negatively charged nitrogen-vacancy (NV) centers in diamond have emerged as a promising high sensitivity platform for measuring magnetic fields at room temperature. Transferring this technology from laboratory setups into products and applications, the total size of the sensor, the overall power consumption, and the costs need to be reduced and optimized. Here, we demonstrate a fiber-based NV magnetometer featuring a complete integration of all functional components without using any bulky laboratory equipment. This integrated prototype allows portable measurement of magnetic fields with a sensitivity of 344 pT/ SqrtHz.
