Comparison of Existing works.

Authors	Stomach position	Electrode position	Coordinates	Disadvantage
[19]	Cutaneous reference points	Proximal electrodes	Placed in the costal margin of the stomach	Commonly used but time consumption
[20]	Sonography method	2 electrodes	Left side of the abdomen and ventral region	Overuse of electrodes may lead to severe problems in accuracy rate
[21]	Cutaneous reference points method	1 electrode	Between umbilicus and xiphoid process	Low signal to noise ratio
[22]	X-ray method	6 electrodes	At least in one channel of the abdomen	Low signal to noise ratio
[23]	Cutaneous reference points method	5 electrodes	Umbilicus and xyphoid process	Pick up propagation is too low
