Preterm labor is one of the major public health problems in the developing countries, where accessibility to health facilities is low in some areas. Home monitoring devices could be good options in this situations. Therefore, we developed a tool for early detection of contractions. The type of signal, artifacts removing way, a method for sending signals safely, detecting abnormal contractions method, and evaluation methods were determined. EHG signals were applied to send contractions to mobile application. Alarms were displayed if abnormal contraction is detected. Relative Error and Co-efficient of variation were calculated for evaluation of accuracy and repeatability of device, respectively, which were acceptable. This portable, low weight, low cost and easy to use uterine contraction-monitoring device could be used in urban and rural health centers, at home and by pregnant women who are living in hard-to-reach places. This may help early awareness and take action to prevent premature birth.

Vital signs monitoring is a fundamental component of ensuring the health and safety of women and newborns during pregnancy, labor, and childbirth. This monitoring is often the first step in early detection of pregnancy abnormalities, providing an opportunity for prompt, effective intervention to prevent maternal and neonatal morbidity and mortality. Contemporary pregnancy monitoring systems require numerous devices wired to large base units; at least five separate devices with distinct user interfaces are commonly used to detect uterine contractility, maternal blood oxygenation, temperature, heart rate, blood pressure, and fetal heart rate. Current monitoring technologies are expensive and complex with implementation challenges in low-resource settings where maternal morbidity and mortality is the greatest. We present an integrated monitoring platform leveraging advanced flexible electronics, wireless connectivity, and compatibility with a wide range of low-cost mobile devices. Three flexible, soft, and low-profile sensors offer comprehensive vital signs monitoring for both women and fetuses with time-synchronized operation, including advanced parameters such as continuous cuffless blood pressure, electrohysterography-derived uterine monitoring, and automated body position classification. Successful field trials of pregnant women between 25 and 41 wk of gestation in both high-resource settings (n = 91) and low-resource settings (n = 485) demonstrate the system’s performance, usability, and safety.
