Fetal heart rate monitors, at their current status, are best optimized for detection of a single fetus during pregnancy. Dr. Naegle presented the concept of a fetal heart rate monitoring array to the students in the Senior Capstone Design course through the Washington University department of Biomedical Engineering. The goal of this project is to design a system that can accurately detect and differentiate fetal heart rates between any number of fetuses without causing harm to the mother or her fetuses. The design prototype will contain the ability to record a fetal heart rate signal though an amplification and filtering circuit, analyze the captured signal through computer algorithm, and output information that alerts health care professionals on the quality of the fetal heart rate detected. The circuit developed for the prototype will acquire, amplify, and filter the raw signal data. The computer algorithm will utilize the altered signal and reduce noise and identify fetal heart beats from the signal. Additionally, the algorithm will differentiate multiple detected fetal heart rates while being aware and ignoring the maternal heart rate that is also present. The fetal heart rate monitoring array will ultimately increase the accuracy and ability to monitor multiple fetal heart rates in a single mother simultaneously. By the finish of the academic year, the prototype will contain both working signal recording hardware along with a working algorithm to process the signal.
