ECG, EEG and IMU data for local motion artefact removal

dataset
posted on 20.09.2021, 10:12 by Christopher BeachChristopher Beach, Mingjie Li, Ertan Balaban, Alex CassonAlex Casson
ECG and EEG data collected from a single participant using our custom device with inertial measurement units (IMUs) placed on each electrode, to enable recording of local motion activity (accelerometer and gyroscope) during electrophysiological recordings. This is to enable improved motion artefact removal. Please see paper for description of the device, placement of the electrodes and testing procedure.

Data is in CSV format, with a sample rate of 220 Hz.

If using this data please cite:

In our paper we take plot the following sections of data:
ECG:
Lines 1939:5039 (for the good filtering case)
Lines 7100:10200 (for the poor filtering case)
EEG:
Lines 7279:10439
