Abstract
An apparatus for measuring biopotential signals comprises a plurality of electrodes embedded or affixed to a wearable worn about the torso of a pregnant subject, enabling the non-invasive acquisition of electrocardiographic signals and the extraction of separate fetal and maternal electrocardiographic signals therefrom. The wearable is stretchable or adjustable to accommodate any maternal body habitus and can advantageously employ dry physiologic electrodes to eliminate the step of skin preparation and provide longer-term monitoring that is also both more convenient and more comfortable.
