AI Technical Summary
Existing technologies struggle to accurately detect and differentiate weak magnetic signals from the heart amidst strong background magnetic fields without the need for shielding, leading to poor signal resolution and potential false alarms in cardiac disease detection.
A device utilizing nitrogen-vacancy (NV) magnetometers in a geometric arrangement, integrated into everyday objects like cushions or mattresses, enables high-resolution, contactless monitoring of heart magnetic signals by employing gradiometer connections and vectorial magnetic field measurements, eliminating the need for magnetic shielding.
Enables precise detection of cardiac signals, allowing early identification of heart diseases such as atrial fibrillation and myocardial infarction, while suppressing background fields, thus reducing false alarms and improving diagnostic accuracy.
