A new method for long-term home monitoring of fetal movement by pregnant women themselves.

Fetal movement is one index of fetal well-being. We designed and built a new recorder based on fetal movement acceleration measurement (FMAM). The FMAM recorder has a newly developed, capacitive acceleration sensor that can detect the oscillations of the maternal abdominal wall caused by fetal movements. In this study, the recorder was examined for its suitability for long-term home monitoring of fetal movement by pregnant women themselves.
