Abstract: Fetal wellbeing monitoring apparatus including a generally flattened hemispherical housing and a turret-like user interface- having a user operated control panel for controlling operation of the fetal wellbeing monitoring apparatus and providing fetal wellbeing information to an expectant mother. Fetal wellbeing monitoring apparatus including a fetal motor activity sensor including a base plate with a base plate topside and a base plate underside with an elongated planar strain gauge film element defining a nominal measurement plane in a non-flexed state, and having a variable electrical property proportional to resilient elastic flexion in a transverse direction to the measurement plane on application of a bending moment and a fetal motor activity determination module for processing time varying information for determining fetal motor activity. Two-ply pad for use with the fetal wellbeing monitoring apparatus.
