Key result
Inframammary and scapular electrode placements minimize motion artifacts in wearable ECG clothing.
Why the study?
Smart clothing for ECG monitoring has a weakness on motion artifacts caused by shifting electrode positions affected by skin changes during movement, and optimal electrode locations to reduce these artifacts were not well established.

Recently, according to change of lifestyle and increase of concerning in health, needs of the smart clothing based on the vital sign monitoring have increased. Along with this trend, smart clothing for ECG monitoring has been studied various way as textile electrode, clothing design and so on. Smart clothing for ECG monitoring can become a comfortable system which enables continuous vital sign monitoring in daily use. But, smart clothing for ECG monitoring has a weakness on artifact during motion. One of the motion artifact caused by shifting of the electrode position was affected skin change by motion. The aim of this study was to suggest electrode locations for clothing of ECG monitoring to reduce of motion artifacts. Therefore, change of skin surface during the movement were measured and analyzed in order to find location to minimize motion artifacts in ECG monitoring clothing by 3D motion capture. For the experiment, the subjects consisted of 5 males and 5 females in their 20' with average physique. As a result, the optimal location for ECG monitoring was deducted under the bust line and scapula which have least motion artifact. These locations were abstracted to be least affected by movement in this research.

Cho et al. (2015) studied Healthy volunteers (n=10). 9 representative upper body motions vs. Static posture (resting state) was evaluated on Skin surface change rate during movement to determine optimal ECG electrode location. The optimal sensing locations for ECG monitoring clothing to minimize motion artifacts were identified as under the bust line (V4, V5 for men; V2, V4 for women) and the scapula region.
