Abstract
Disanje ili respiracija je fiziološki i automatski proces u kojem organizam ili tkivo apsorbira molekularni kisik (O2), a izlučuje ugljični dioksid (CO2). Postoje različite metode pomoću kojih je moguće mjeriti disanje, a neke od njih su spirometrija i tjelesna pletizmografija. Ove dvije metode nisu pogodne za kontinuirano praćenje disanja pa se za takvo mjerenje koriste akustični senzori, senzori vlažnosti, oksimetrije, akcelerometri te otpornički senzori. Razvijen je bežični sustav koji kontinuirano prati disanje. Sustav se sastoji od vodljive gume spojene u Wheatstoneov most. Signal s mosta se filtrira nisko-propusnim filtrom te dolazi do analogno-digitalnog pretvornika koji je spojen na mikrokontroler. Računalo s mikrokontrolerom komunicira putem Bluetooth komunikacijskog protokola, a primljeni podaci se prikazuju u stvarnom vremenu. Za programiranje mikrokontrolera je korišteno razvojno okruženje Keil uVision, za prikaz podataka programski jezik Python, a za razvijanje tiskane pločice programski alat Altium Designer.
Abstract (english)
Breathing or respiration is a physiological and automatic process in which an organism or tissue absorbs molecular oxygen (O2) and produced carbon dioxide (CO2). Some methods for measuring respiration are spirometry and body plethysmography. These two methods are not suitable for continuous monitoring of breathing. Therefore, for such measurement acoustic sensors, humidity sensors, oximetry, accelerometers and resistance sensors are used. A wireless system for continuous monitoring of breathing is developed. The system consists of a conductive rubber connected to the Wheatstone bridge. The signal from the bridge first propagates through the low-pass filter and then through analogue-to-digital converter connected to the microcontroller. The computer communicates with the microcontroller via Bluetooth and displays received data in real-time. For software development and data visualization, the Keil uVision development environment and Python programming language are used, respectively. Finally, the Altium Designer programming tool is used for developing the printed circuit board.
