This Chapter describes the methods of a proximity coupling RF vital sensor. The methods are mainly divided into two categories: the chest wall sensor and the wrist pulse sensor. For each part, the theoretical considerations, simulation results, and experimental results on methods for efficiently enhancing the sensitivity of the sensors are described in detail. In addition, we introduce an autoregressive (AR) model which is one of the parametric spectral analyses suitable for vital sign detection.
