    Magnetic human body communication based on double-inductor coupling
    (IEEE, 2017) Hernández-Gómez, Yicely K.; Álvarez Botero, Germán Andrés; Bacca Rodríguez, Jan; Sousa, Fernando Rangel de; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    This paper proposes a new technique for Human Body Communication (HBC) that uses the magnetic coupling in transmitter and receiver. A discussion about the presence of parasitic paths, when magnetic coupling is used in the transmitter, and electrical coupling is used in the receiver is presented; showing that the technique presented here, reduces the influence of the surrounding environment at the same time that simplifies the conventional reception schemes. In addition, a physical-based model is presented, obtaining a good model-experiment correlation up to 20 MHz. This results suggest the possibility to use the double-inductor coupling technique for the HBC channel characterization, contributing in the design of portable applications for communications systems.

    Characterization and modeling of the capacitive HBC Channel
    (IEEE, 2015) Pereira, Maicon D.; Álvarez Botero, Germán Andrés; Sousa, Fernando Rangel de; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    The increasing interest in wireless body area networks has created the need for alternative communication schemes. One example of such schemes is the use of the human body as a communication medium. This technology is called human body communication (HBC), and it offers advantages over the most common radiation-based methods, which makes it an interesting alternative to implement body area networks. The aim of this paper is to identify the influence of a fixture on the HBC channel characterization, and an extended model that includes the test fixtures to explain the measured channel response is proposed. The model was tested against the channel measurement results, and a good experiment-model correlation was obtained. The results show that the test fixture has a nonnegligible influence and that an extended model, based on the physical meaning of the phenomena involved, helps to explain the channel frequency profile results and behavior.
