Abstract

U ovom radu istražene su mogućnosti integriranih sklopova za mjerenje bioelektričnih signala te je proveden pregled integriranih sklopova dostupnih na tržištu, s naglaskom na MAX30001 i MAX86150. Istražene su mogućnosti STM32WB55 mikrokontrolera i njegovog sučelja za Bluetooth bežičnu vezu. Nadalje, proučeno je i opisano razvojno sklopovlje za integrirane sklopove MAX30001, MAX86150 i STM32WB55 razvijeno na Fakultetu elektrotehnike i računarstva u Zagrebu. Razvijena je programska potpora za razvojne uređaje koja konfigurira sklopovlje, prikuplja podatke o bioelektričnim signalima i šalje ih putem Bluetooth bežičnog komunikacijskog sučelja. Razvijeno je ispitno okruženje za spomenuta razvojna sklopovlja koje se sastoji od aplikacije za računalo i aplikacije za pametni mobitel. Aplikacije imaju mogućnost povezivanja s uređajima putem Bluetooth bežičnog komunikacijskog sučelja, mogućnost prikupljanja podataka, upravljanja mjerenjima i pohranjivanja podataka. Programska potpora aplikacije za računalo razvijena je u programskom jeziku Python koristeći Qt alat. Programska potpora aplikacije za Android pametni mobitel razvijena koristeći C# programski jezik i platformu Xamarin. Naposljetku, provedena su testiranja rada ispitnog okruženja.

Abstract (english)

This paper investigated the capabilities of integrated circuits for measuring bioelectric signals and provides an overview of devices available on the market, with an emphasis on the MAX30001 and MAX86150 integrated circuits. The capabilities of the STM32WB55 microcontroller and its interface for Bluetooth wireless connection were explored. Furthermore, the development hardware for integrated circuits MAX30001, MAX86150, and STM32WB55 developed at the Faculty of Electrical Engineering and Computing in Zagreb was studied and described. Software for the above mentioned devices has been developed, including hardware configuration, bioelectrical signals collection, and data streaming by means of Bluetooth wireless protocol. A test environment was developed for the development hardware, consisting of a computer application and a smartphone application. Applications can connect to devices via Bluetooth wireless technology, collect data, manage measurements, and store data. Computer application software was developed in the Python programming language using the Qt framework. Android smartphone application was developed using C# programming language and Xamarin platform. Finally, evaluation of the complete test environment was performed.
