Abstract: Provided are a physiological signal measurement garment and a physiological signal processing system. The physiological signal measurement garment includes: a main garment body which is formed of an elastic fabric and includes a mesh structure and an elastic band; at least one physiological signal sensing electrode sewn on the garment body; a physiological signal transmission unit which is sewn on the garment body and transmits a physiological signal sensed by the physiological signal sensing electrode; and a physiological information measurement module that measures various kinds of physiological information from the physiological signal, which is sensed by the physiological signal sensing electrode and transmitted through the physiological signal transmission unit. The physiological signal measurement garment is more comfortable for a wearer than similar existing garments and can measure a physiological signal with higher accuracy.
