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.

本数据集采集自20名受试者，采集总时长为1小时，实验围绕上半身生物阻抗开展，具体实验目标如下：
a) 评估运动、外加压力、温度变化及姿势改变在皮肤-电极（Skin-Electrode, SE）界面引发的外部扰动对生物阻抗测量结果的影响；
b) 评估10kHz至100kHz多频率区间内，生物阻抗测量中由伪影引发的失真程度；
c) 评估外部扰动诱发的阻抗变化的可重复性；
d) 构建多频身体生物阻抗数据集，用于开发可识别外部扰动伪影特有特征的算法，并后续应用于伪影抑制任务。

该数据集包含10个频率下生物阻抗数据的伪影标签、四极构型下4个电极采集的皮肤-电极阻抗数据，以及加速度计数据。
