Texas Tech University researchers Kai Wu and Minxiang Zeng received a four-year, $588,371 grant from the National Institute of General Medical Sciences (NIGMS) to develop wearable magnetic sensors for cardiac monitoring.12
The project focuses on organic granular magnetoresistive (OgMR) sensors using 3D printing, nanoparticles, quantum phenomena (tunneling and hopping), and AI/machine learning for real-time arrhythmia detection and classification of over 10 abnormal heartbeats.12
These flexible, low-cost sensors, like temporary tattoos, enable non-invasive, 24-hour heart monitoring, improving early detection, especially for post-surgery patients and rural areas.12
The news was published on February 10, 2026, highlighting potential to make advanced magnetocardiography (MCG) accessible beyond bulky traditional systems.24
