中国科学家为智能手表开发高灵敏度磁传感器

作者 PulseAugur 编辑部 · [1 个来源] · 2026-08-15 03:00

中国科学家开发出一种高灵敏度霍尔效应磁传感器，其尺寸足以安装在智能手表中，能够探测到微弱的磁场。这项发表在《物理评论快报》上的突破克服了此类传感器在灵敏度和噪声之间长期存在的权衡。该技术有可能使智能手表等设备能够探测到水下500米处的潜艇。 AI

中国磁传感器突破或助智能手表探测500米深潜艇

Picture a fisherman hauling in his nets on a calm morning at sea, when his smartwatch suddenly vibrates with an alert: “Magnetic anomaly detected – possible submarine passing 500 metres below.” Far‑fetched as it sounds, Chinese scientists have just taken a decisive step towards m…
