A wearable sensor technology enables us to conduct scientific research on our everyday lives by describing everyday phenomena quantitatively. For example, observing and understanding children's behavior in everyday lives is required for developing preventive measures of children's injuries. This paper describes a wireless wearable electromyography (EMG) sensor for measuring behavior of children in a daily living space. The system of a wireless wearable EMG sensor developed by the authors is presented. This paper proved the effectiveness of the developed system by conducting in situ measurement of 47 "playing" nursery school toddlers. This paper also presents the analysis of the play action data and its application.
