Ability of the Polar Wearables to Detect Fetal Heart Rate - Pilot Clinical Study

The aim of this clinical pilot study is

1. to evaluate the ability of the wearables to detect fetal heart rate
2. to evaluate the ability to distinguish the fetal ECG from the ECG of the mother

The participating pregnant women will wear the Polar wearables (chest band, smart watch, arm band) for 15 minutes during of which, the data will be collected with all three wearables and patient monitor (reference device). The data from the wearables will be compared with the patient monitor data referred as golden standard. Background information will be collected with questionnaires from the participants. The data collection will be conducted in hospital environment.
