Artefacts due to Skin electrode impedance disturbance in multi-frequency bio-impedance measurements

This dataset is taken from 20 subjects over a duration of 1 hour where experiments were done on the upper body bio-impedance with the following objectives:a) Evaluate the effect of externally induced perturbance at the SE interface caused by motion, applied pressure, temperature variation and posture change on bio-impedance measurements.b) Evaluate the degree of distortion due to artefact at multiple frequencies (10kHz-100kHz) in the bio-impedance measurements.c) Evaluate the repeatability of induced impedance change due to external perturbance.d) Create a multi-frequency body bio-impedance dataset to develop an algorithm identifying features specific to induced artefacts, and subsequently, to employ artefact suppression.The dataset contains artefact labels for bio-impedance data at ten frequencies, skin-electrode impedance data from four electrodes in tetrapolar configuration and accelerometer data.
