A compact Non-Invasive WearableVital Signal Monitoring System

On-body vital signal detection and communication is a popular option for applications especially health-care. This paper proposes, simulation design and development of a wearable compact antenna, which provide an alternative solution to on-body vital signals such as breathing and heart rate signal. The vital signals were measured by connecting proposed antenna to the chest using vector network analyzer and feasibility of this new method was verified by comparing the obtained vital signals to the commercial devices and testified the methodology by using Bland Altman analysis. The results obtained shows the 4.8% and 6.4% of the respiration result and heart rate result are out of 95% confidence interval.
