fetal movement acceleration data

This dataset contains accelerometer-recorded fetal movement signals with 16 different pregnant women The dataset contains signals from one accelerometer placed on the abdominal wall of the pregnant women. Note: The file format is .mat, which is recognized by the Matlab software. the "xxxxxx_bp" files contain the signals of the maternal perception push-button markers (the mother was required to press a push-button every time she felt one fetal movement), and the "xxxxxx_signal" files contain acceleration data from the 3 axes (x, y, and z). Hardware settings: accelerometer: ADXL355 from ANALOG DEVICES Sampling frequency: 500H
