Abstract
The growing demand for portable healthcare instruments results in the rapid development of implantable and wearable medical devices. These devices can be arranged in a wireless body area network (WBAN) to monitor multiple vital signs. The physiological signals of the sensors are managed by the network, and the data communication is realized by the radios in the sensor nodes. In this way, the healthy radios play an important role in configuring the WBAN, while the power consumption of the radio part dominates the overall life time. Therefore, low power is the main design requirement in healthy radios, which can also minimize the battery size of each sensor node. In this chapter, we will briefly discuss three main kinds of healthy radios, operating in the schemes of narrowband, UWB, and HBC. The features of the transceivers will be summarized, and recent design examples will be described.
