1. A fetal monitoring device, comprising:
- a piezofilm sheet;
a first electrode;
a second electrode;
a controller operably connected to the piezofilm sheet, the first electrode and the second electrode, the controller receives an acoustic signal from the piezofilm sheet and a biopotential measured between the first electrode and the second electrode and derives at least one of fetal heart rate and fetal motion detection from the acoustic signal and at least one of maternal heart rate and uterine activity from the biopotential and derives an index of fetal health from the at least one of fetal heart rate and fetal motion detection and at least one of maternal heart rate and uterine activity; and
an indicator operable by the controller to present the derived index of fetal health.

Abstract
A fetal monitoring device includes a piezofilm sheet, a first electrode, and a second electrode. A controller is operably connected to the piezofilm sheet, first electrode, and second electrode and receives a biopotential and a piezofilm signal. The controller derives at least one of a maternal heart rate and a uterine activity for the biopotential and derives at least one of a fetal heart rate and fetal motion detection from the piezofilm signal. The controller derives an index of fetal health and operate an indicator to present the derived index of fetal health.

11. A fetal monitoring device, comprising:
-
at least one glove configured to be worn by a patient, the glove having a forehand side, a backhand side, a thumb region, and at least one finger region; a piezofilm sheet secured to an exterior of the forehand side of the at least one glove; a first electrode secured to the forehand side of the thumb region; a second electrode secured to the forehand side of at least one finger region; a controller electrically connected to the piezofilm, first electrode, and the second electrode, the controller receives a piezofilm signal from the piezofilm sheet and a biopotential measured between the first electrode and the second electrode and derives a fetal heart rate and a fetal motion detection from the piezofilm signal and derives a maternal heart rate and a uterine activity from the biopotential and derives an index of fetal health from the fetal heart rate, the fetal motion detection, the maternal heart rate, and the uterine activity; and an indicator operable by the controller to present the index of fetal health. - View Dependent Claims (12, 13, 14, 15)

16. A method of monitoring the health of a fetus, the method comprising:
-
providing a mother with a wearable garment that comprises a piezofilm sheet, a first electrode, a second electrode, and a controller; receiving at the controller a biopotential between the first electrode and the second electrode; receiving at the controller an acoustic signal from the piezofilm; deriving with the controller at least one of fetal heart rate and fetal motion detection from the received acoustic signal, deriving with the controller at least one of maternal heart rate and uterine activity from the received biopotential; deriving an index of fetal health from the derived at least one of fetal heart rate and fetal motion detection and at least one of maternal heart rate and uterine activity; visually presenting the index of fetal health. - View Dependent Claims (17, 18, 19, 20)
