摘要：
We have previously reported a wearable magnetocardiography (MCG) sensor that utilizes a coil array capable of detecting the weak magnetic fields generated by the heart. In this work, we improve upon our previous design by reducing the number of coils from seven (7) to one (1) while also achieving significantly better detection results. Experimental validation on a human subject shows an increase in heart beat detection accuracy from 28.4% to 96.8%. Key to this improved performance is a new signal processing method that significantly reduces noise. Given the increasing importance of MCG as a reliable and non-contact method of assessing cardiac health and cognitive workload, the proposed sensor is expected to have significant clinical impact.
