Monica Healthcare has developed a series of innovative wearable devices that use wireless technologies to facilitate globally accessible obstetric services in the home and hospital. The patented technology is based on the acquisition of electro-physiological signals that can be passively detected by electrodes positioned on the maternal abdomen. From these signals a number of a parameters including fetal position, fetal heart rate, maternal heart rate, uterine activity, gross fetal movements and parameters describing Fetal ECG morphology can be extracted, in real time, and over an extended period of the time.
