Miniature sensor for Doppler ultrasound fetal heart rate monitoring. Increased patient comfort and ergonomy in use

We have developed light weight miniature ultrasonic sensors for use in FHR (Fetal Heart Rate) monitoring. These sensors can be fixed to the maternal abdomen using double sided tape rounds identical to those used in ECG. It is shown that these sensors have performances comparable to traditional sensors while greatly increasing patient comfort and ergonomy in use.
