摘　　要：Cardiovascular diseases(CVDs)are fatal chronic diseases,where electrocardiography(ECG)monitoring could be a prominent solution for early diagnosis.In spite of available commercialized,multilead ECG devices,bulky formats,discontinuous monitoring,and no safety alarm system significantly limit their practical applications.Herein,we present a soft,and stretchable,three-lead ECG device allowing continuous monitoring and wireless transmission of ECG signals.A newly developed organohydrogel patch with a strong adhesive ability(~9.9 kPa)and higher conductivity(~6.5 kΩ)is applied for high-quality ECG signals collection.With a long operation duration(6.5 h)and wireless transmission distance(20.9 m),it could fulfill most of the daily applications.Machine learning algorithms and the graphical user interface are used for real-time ECG monitoring and cardiac abnormalities diagnosis.The vibratory flexible actuator,which is triggered by cardiac abnormalities that need immediate medical treatment,is also integrated as a warning system for the user.As a newly reported stretchable multi-lead ECG device for long-term ECG signal monitoring,there is a high potential for improving users'life quality with the high-risk population of CVDs.
