Abstract

One embodiment provides a garment for measuring biological information, a measurement system, a measurement device and a method of controlling thereof capable of measuring biological information with accuracy regardless of variations of each examinee. When an examinee wears a shirt, four limb electrodes are arranged at positions so that the electrodes cover the body surface other than around the clavicle. At that time, the four limb electrodes are assigned to positions so that they cover about the pelvis. Also, during the use of the shirt, chest electrodes cover from the body surface (around lower part of left side of the body) of a presternal region around the left thorax in a perpendicular direction of the body axis (a direction perpendicular to the length of the shirt) and the electrodes are assigned so as to cover from the body surface around the fourth rib to that around the sixth rib.
