New sensor combines sensitivity and range

Scientists created a laser-enhanced device using nitrogen-vacancy centers inside diamond. This technology improves the ratio of sensitivity to dynamic range by up to 590 times compared to current methods. The system operates at room temperature while measuring both magnitude and direction of magnetic fields.

Breakthrough enables better medical tools

The results were published in the journal Nature Communications. These findings open new possibilities for diagnostics, navigation systems, and resource exploration projects. The approach avoids previous trade-offs between high sensitivity and robust dynamic range.
