System and method for optimal sensor placement and signal quality for monitoring maternal and fetal activities

A system for achieving optimal placement of a sensor array on a maternal subject's abdomen and enhanced signal quality for monitoring maternal and fetal activities, the system comprising:

• a monitoring device and a computing unit,
• wherein the monitoring device is configured for monitoring maternal and fetal activities, the monitoring device comprising:
• a plurality of sensors arranged in a pre-determined layout forming the sensor array comprising the plurality of sensors, one or more reference electrodes and a ground electrode, wherein the sensor array is configured for capturing biological data associated with maternal and fetal activities using one or more signal modalities;
• a data acquisition and transmission unit for processing and transmitting the captured biological data to the computing unit;
• wherein the system is configured for performing a signal quality assessment and selecting the optimal sensors to ensure reliable monitoring of maternal and fetal activities;
• and
• wherein the computing unit is configured for providing guidance to a user for placement of the monitoring device on the maternal abdomen at a determined position or providing guidance to improve signal quality, wherein the guidance is provided using an application installed in the computing unit and executed based on:
• one or more subsets of the captured biological data and personal data, and
• at least one of a statistical model and a machine learning model;
• wherein the personal data comprises maternal height, maternal weight, uterus width, abdominal width, abdominal depth, abdominal circumference, symphysiofundal height, symphysis to umbilicus distance, umbilicus to xiphisternum distance, midline to fundus distance, or combinations thereof.
