Bio-signals including electrocardiogram (ECG), respiration rate, motion-related signals, plantar pressure distribution are important for monitoring and assessing a person’s health status. Via some of the bio-signals, some diseases or abnormalities such as cardiovascular diseases or a human fall can be detected. However, the traditional health monitoring systems have limitations as they are expensive, not-easy-to-use, stationary, inconvenient and uncomfortable to use. It is required an advanced solution for dealing with the limitations while maintaining a high quality of services such as high-quality signals and accuracy. Therefore, we present a novel wireless wearable health monitoring system in this paper. The system consists of an upper limb device and a lower limb device using flexible materials such as polydimethylsiloxane-graphene compound and textile materials for collecting different ECG, EMG, respiration rate, motion-related signals, plantar pressure distribution. The complete system is implemented, tested and verified in a clinical environment in a hospital. The results show that the system can obtain high-quality bio-signals and can be a potential application for both home-care and hospital-care.
