Highly Sensitive Micro-magnetic Sensor for Cardiac Imaging

This project will develop a novel hybrid MEMS-magnetoresistive sensor to facilitate highly sensitive medical imaging of the human heart. The sensor will measure and display two-dimensional real-time images of the magnetic fields generated by the heart’s activity, providing critical information about cardiac health. By using very small sensors (~1 mm2) and improved room-temperature low-frequency resolution MR sensors, the researchers will create a small, very sensitive, non-invasive magnetic device that will both consume little power and be portable. In the future, patients may be able to use it in medical institutions or directly at home.
