Measurement of around-body creeping waves using wearable sensor modules

Wireless Body Area Network (WBAN) technology holds great potential for many applications such as remote healthcare monitoring and personal activity tracking. A vector network analyzer can be used to measure on-body channel changes due to different activities, but they are much too costly and bulky for most WBAN applications. Small, wearable, affordable sensors must be developed for practical WBAN usage. This paper investigates two methods for replacing the network analyzer from an on-body wave propagation measurement setup.
