Sleep Position Pattern Recording

The main goal of this study is to validate the accuracy of the body position detection by non-invasive wearable monitors (Skiin garments, Myant Medical Corp) during sleep in pregnant participants. This is a first step towards examining the association between maternal sleep position and fetal growth.
