In this study, we fabricated a stretchable strain gauge consisting of elastomer-based tube and conductive dispersion liquid containing conductive polymers for the measurement of joint motion. We evaluated the relationship between the rheological properties of conductive fluid and the resistive response of strain gauge. We attached this strain gauge on a finger and succeeded in detecting abnormal motion during the guitar playing by a machine learning model.
