Abstract: Systems and methods of maternal and fetal monitoring include acquiring ultrasound physiological data with an ultrasound transducer. A plurality of electrodes acquire biopotential physiological data from the skin of a patient. A controller receives the ultrasound and biopotential physiological data and calculates fetal heart rate (fHR) values, maternal heart rate (mHR) values, and uterine activity (UA) values from the ultrasound and biopotential physiological data.

Abstract: An ultrasound system includes a transducer array including a flexible substrate, ultrasound transducer elements disposed on the flexible substrate and configured to transmit and acquire ultrasound signals that propagate in a body of a patient, and strain sensors coupled to or integrated into the flexible substrate and configured to measure a strain in the flexible substrate generated by flexing the flexible substrate. The ultrasound system also includes a processor coupled to the ultrasound transducer elements and the strain sensors, wherein the processor is configured to process the signals acquired by the ultrasound transducer elements based at least in part on the strain measured by the strain sensors.

Abstract: A maternal and fetal monitoring system includes a detection probe configured to conduct physiological measurements on a maternal abdomen, the detection probe comprising a probe housing configured to be attached to the maternal abdomen, and a plurality of electrodes integrated into the probe housing and configured to acquire biopotential physiological data from the maternal abdomen. At least one controller is configured to calculate fetal heart rate (fHR) values, maternal heart rate (mHR) values, and/or uterine activity (UA) values based on both the physiological measurements and the biopotential physiological data, and a graphical display communicatively connected to the controller to receives and visually presents the calculated fHR values, mHR values, and/or UA values.
