diseases in everyday life, but their large form factors or battery power limitations still remain to be solved. Security and/or requirements of interference resilience are stringent for health monitoring, and therefore, using an open-air wireless ISM band [1] is not suitable for a health monitoring body sensor network (BSN). This paper presents a self-configured wearable BSN system with high efficiency wirelessly powered sensors that continuously monitor ECG and other vital signals at the selected locations on the body with low power consumption. Figure 17.3.1 shows the proposed wearable BSN system. The health monitoring chest band with integrated inductor array is worn over the chest where the sensors are put on at arbitrary locations. The chest band finds the positions and types of sensors, and provides power wirelessly only to the
