Abstract :
A pair of low-power wireless sensor nodes, operating in the 2.45 GHz ISM band, are used to record the radio propagation of a particular on-body channel, the waist-chest channel. The recorded time-sampled radio link data is analysed in the frequency domain. It is shown that the wave propagation along the human body´s surface embeds not only the radio channel characteristics, but also physiological features.
