A new device for recording fetal movements is presented. This device is composed of 2 sensors, incorporating a highly sensitive piezoelectric material. It is sensitive to rapid straining forces such as fetal movements and relatively insensitive to steady, slow movements such as uterine contractions and maternal respiratory movements. In this study of 20 women, the sensors were placed on 2 different zones of the abdomen, usually above the umbilicus. There was a good correlation between fetal movements recorded by the device and those felt by the patients. Seventy percent of all observed fetal movements recorded by the device were registered simultaneously by the women. The device recorded 90.4% and the women recorded 79.7% of all such movements.
