Abstract
Prijenos signala ljudskim tijelom (eng. Intrabody communication, IBC) je relativno mlada tehnologija koja koristi tijelo kao medij za prijenos informacija. Začetnik ove vrste prijenosa signala je T. G. Zimmerman, koji je 1996. godine konstruirao prvi uređaj za prijenos signala ljudskim tijelom. IBC sustav sastoji se od odašiljača i prijamnika koji su sa tijelom spojeni preko signalne i referentne elektrode. Signalna elektroda služi za prijenos signala po ljudskom tijelu dok referentna služi da bi se zatvorio povratni put signala. Obje elektrode su postavljene na tijelo te galvanski odvojene od tijela. Sustav pokazan u ovome radu sastoji se od odašiljača, prijamnika te bežičnog modula za vezu prema računalu. Odašiljač šalje Manchester kodirani signal direktno u tijelo gdje se zbog visokopropusne karakteristike ljudskog tijela rastući brid Manchester kodiranog signala pretvara u pozitivni impuls, a padajući brid Manchester kodiranog signala u negativni impuls. Zadaća prijamnika je filtrirati primljene impulse, pojačati ih te rekonstruirati u poslani Manchester kodirani signal. Obrađeni primljeni signali se zatim šalju na računalo putem bežičnog modula NRF24L01
Abstract (english)
Intrabody communication (IBC) is relatively new method which uses the human body as a signal transmission medium. The founder of this method is T.G. Zimmerman who constructed the first intrabody device in 1996. The parts of IBC system are transmitter and receiver, which are connected to the human body via signal and referent electrodes. The signal electrode is used to transfer signal through the body and the referent electrode is used to close signal return path. Both electrodes are placed on body and galvanically isolated from the human body. The IBC system developed in this master thesis consists of transmitter, receiver and wireless module for connection with a PC. Transmitter sends Manchester coded signals directly into the body, where the rising edge of a Manchester signal is transformed into the positive impulse while the falling edge is transformed into the negative impulse, due to the high-pass characteristic of the human body. Receiver must filter incoming impulses then amplify them before they can be reconstructed back in Manchester coded signal. Reconstructed signal is then sent to PC via NRF24L01 wireless module.
