Abstract

U ovom je završnom radu predstavljena i analizirana bežična tehnologija prijenosa signala ljudskim tijelom (IBC). Na temelju općenite teorijske podloge o metodi IBC prijenosa i istraživanja izloženog u Maity i sur. [3] koje karakterizira ljudsko tijelo za kapacitivni elektrostatski prijenos, razmatrane su tehnike modeliranja IBC kanala. Uzimajući u obzir dostupna saznanja i analize problematike modeliranja i validacije rezultata, postupno je prikazano modeliranje sustava za prijenos signala ljudskim tijelom izvedeno koncentriranim parametrima. Nadalje, opisan je model koji je izveden kao kombinacija modela ljudskog tijela za prijenosne uređaje iz Maity i sur [3] i modela ruke iz Ž. Lučev Vasić [1] te je prilagođen za prikaz prijenosne karakteristike IBC sustava ruke bez galvanskog odvajanja. Svi su modeli razvijeni i simulirani u programskom paketu ADSTM 2017 s naglaskom na procjenu utjecaja odabranih parametara (kao što su raspored elektroda odašiljača i prijamnika te razmak između parova elektroda) na frekvencijsku karakteristiku prijenosnog kanala.

Abstract (english)

In this bachelor thesis, wireless Intrabody communication (IBC) technology is presented and analyzed. Based on a general IBC theoretical background and research in which characterization of capacitive electro-quasistatic coupling is reported (Maity et al. [3]), intrabody communication channel modeling techniques are investigated. Considering available modeling issues and result validation, procedure of an intrabody communication system modeling based on lumped parameters is described. Furthermore, equivalent circuit model derived as a combination of circuit model with a wearable transmitter and receiver from [3] and human arm model from [1] is developed and described. This model is adjusted for determining transfer function of intrabody communication system without galvanic decoupling. All models were developed and simulated in ADSTM 2017 software package, with the accent on observing the influence of the selected parameters (like transmitter and receiver electrode configuration and distance between the electrodes) on transmission characteristics of an IBC channel.
