We develop a novel wearable fetal electrocardiogram (fECG) monitoring system consisting of an abdominal patch that communicates with a smart device. The system has two main components: the fetal patch and the monitoring app. The fetal patch has electronics and recording electrodes fabricated on a hybrid flexible-rigid platform while the Android app is developed for a wide range of applications. The patch collects the abdominal ECG (aECG) signals that are sent to the smart device app via secure Bluetooth Low Energy (BLE) communication. The app software connects to a cloud server where processing and extraction algorithms are executed for real-time fECG extraction and fetal heartrate (fHR) calculation from the collected raw data. We have validated the algorithms and real-time data recordings on pregnant subjects yielding promising results. Our system has the potential to transform the currently used fetal monitoring system to an effective distanced and telematernity care.
我们开发了一种新型的可穿戴胎儿心电图 (fECG) 监测系统，由一个与智能设备通信的腹部贴片组成。该系统有两个主要组成部分：胎儿贴片和监测应用程序。胎儿贴片在混合柔性-刚性平台上制造了电子设备和记录电极，而 Android 应用程序则针对广泛的应用进行了开发。贴片采集腹部心电图 (aECG) 信号，通过安全的蓝牙低能 (BLE) 通信发送到智能设备应用程序。应用程序软件连接到云服务器，在那里执行处理和提取算法，从采集的原始数据中实时提取 fECG 并计算胎儿心率 (fHR)。我们已经对算法和实时数据记录在孕妇身上的验证结果很有前景。我们的系统有可能将目前使用的胎儿监测系统转变为有效的远程和远程母婴保健。
