Biosignal Monitoring Clothing System for the Acquisition of ECG and Respiratory Signals

The detection of biosignals by using a comfortable material is important to improve human health. This paper presents complete wearable system with smart clothing for the long-term monitoring lead-I ECG and respiratory signals. proposed divided into three parts, including biosignal-monitoring clothing, biosignal acquisition device, software platform. integrates fabric-based dry electrodes, conductive fiber traces, high-sensitivity capacitive respiration transducer sense biosignals. challenge integration electrodes in provide high-quality signals clinical use has been overcome clothing. sensed on are collected biosignal-acquisition device through traces specially designed structure. Furthermore, processed sent remote Bluetooth module. according requirement front-end actual measurement accuracy implemented contributed onto reduction effect motion artifact. platform provides real-time health-information analysis. A highly efficient QRS complex algorithm respiratory-rate also proposed. verified MIT/BIH Arrhythmia Database demonstrate achievement high performance. overall measured sensitivity, positive prediction, error rate 99.86%, 99.93%, 0.19%, respectively. signal compared commercial silver/silver-chloride electrode BIOPAC MP36 system. result confirms quality signal, so can be used medical applications. function SS11LA airflow transducer, 19 test subjects 98.74%. Using system, health care daily life achieved.
