The FMAM's accelerometer technology and small size allow the overnight recording of fetal movement at home over the long-term by simply attaching sensors to the pregnant woman's body.
It was developed for the purpose of screening to ensure the well-being of the fetus.
Pregnant women can do the FMAM recording by themselves.
The fetal movement data recorded at various weeks of gestation can be given to obstetricians and midwives for analysis, and the new mother can receive their advice and guidance.

The device itself weighs 290g (with battery); each sensor weighs just 20g.
The unit can be easily handled by the women themselves, and it is possible to record 24 hours a day.
There are two sensors, one recording the fetus and one recording the mother.
The sensor recording the fetus is placed on the abdomen where the mother most strongly feels the baby's movements.
The other sensor is placed on the woman's thigh.
The sensors use accelerometer technology.
Fetal movement can be confirmed by looking at the LCD panel.
Display Example of Fetal Movement
This is a 30-second portion of a recording.
The yellow line in the upper part of the figure shows movement by the mother.
The blue line below that shows movement by the fetus.
These lines indicate three movements by the fetus and no movement by the mother.
At the bottom is a different portion of the recording.
The large movements by the mother overlap with movements by the fetus.
