Abstract
A fetal sensor with a biasing mechanism for biasing the sensor against the fetus, with the biasing mechanism being automatically self-inflating and insertable in compressed form. The biasing mechanism in a preferred embodiment is a compressed foam or sponge which expands upon being exposed to fluid, such as amniotic fluid within the uterus. Thus, the biasing mechanism can be compressed to allow easy insertion, and then can expand once in place to provide the pressure needed to hold the sensor against the fetus.
