This study aims to test the following hypotheses in a single-arm observational study in
 70-100 healthy pregnant multi-ethnic women who will be followed-up from the first trimester
 of pregnancy to the third trimester of pregnancy.
 
 Aim 1: To assess the applicability, acceptability and compliance with the use of a wearable
 smart ring together with smart digital devices (e.g., smart phone) during pregnancy.
 
 Hypothesis 1: The investigators hypothesize that participants will respond favorably to the
 use of the smart ring to monitor their physical activity and sleep during pregnancy.
 
 Aim 2: To assess the association between maternal characteristics (age, pre-pregnancy BMI,
 pregnancy weight gain, stress, anxiety and depression symptoms) with physical activity
 markers (energy expenditure, and step count) and sleep markers (duration, quality, sleep
 onset latency, wake after sleep onset, time in bed and heart rate variability) collected from
 the smart ring in the second trimester of pregnancy.
 
 Hypothesis 2: The investigators hypothesize that specific maternal characteristics will be
 associated with physical activity markers (energy expenditure, and step count), as well as
 sleep markers (duration, quality, sleep onset latency, wake after sleep onset, time in bed
 and heart rate variability).
