Chinese scientists develop sensitive magnetic sensor for smartwatches

Chinese scientists have developed a highly sensitive Hall-effect magnetic sensor, small enough to fit in a smartwatch, capable of detecting faint magnetic fields. This breakthrough, published in Physical Review Letters, overcomes a long-standing trade-off between sensitivity and noise in such sensors. The technology could potentially enable devices like smartwatches to detect submarines from up to 500 meters below the surface. AI
