Ultralow Noise Orthogonal Fluxgates Enabling Weak Magnetic Field and Biomolecular Detection
Abstract Noninvasive detection of ultra-weak biomagnetic signals is crucial for modern biosensing, but conventional magnetic sensors are fundamentally limited by intrinsic noise. Orthogonal fluxgates (OFGs) enable high signal-to-noise-ratio detection of weak magnetic fields, yet...
