Abstract

Ovaj se rad bavi projektiranjem, implementacijom te izradom baterijski napajanog sustava za komunikaciju ljudskim tijelom, čija je svrha ispitivanje svojstava ljudskog tijela kao kanala koristeći omjer broja neuspješno poslanih podataka i ukupnog broja poslanih podataka. Sustav se sastoji od baterijski napajanog odašiljača prilagođenog za komunikaciju ljudskim tijelom, koji u sebi sadrži OOK modulator, te od baterijski napajanog prijamnika koji u sebi sadrži OOK demodulator. OOK modulator implementiran je po načelu digitalne sinteze signala, dok OOK demodulator vrši nekoherentnu demodulaciju. Sustav je implementiran na PSoC 5LP razvojnom sustavu koristeći interne i eksterne komponente, a radi u području frekvencija od 100 kHz do 1 MHz. Sustav se može koristiti za mjerenja utjecaja svojstava ljudskog tijela, utjecaja okoline i/ili položaja tijela te pokreta tijela na kvalitetu prijenosa. Obrada podataka vrši se na računalu.

Abstract (english)

In this master’s thesis battery powered system for Intrabody Communication is designed and developed. The purpose of the implemented system is to estimate various properties of the human body as the communication channel, by using ratio of unsuccessful byte transfers and total number of byte transfers. The system consists of battery-powered IBC-ready transmitter, which contains the OOK modulator, as well as of battery-powered receiver which contains the OOK demodulator. OOK modulator is developed by using direct digital synthesis, while the OOK modulator is performing non-coherent demodulation. The system is implemented in PSoC 5LP development kit by using internal and external components and works in frequency range of 100 kHz to 1 MHz. The system can be used for measuring the influence of body properties, environment conditions and/or body positions on the quality of data transfer. Data processing is done on the computer.
