Abstract

V diplomskem delu, smo se ukvarjali z implementacijo brezžičnega elektrokardiografa s senzorji EPIC. Sama naprava je sestavljena iz treh ločenih delov. Prvi del predstavlja mikrokrmilnik dsPIC33, krmiljenje za baterijo in bluetooth modul. Drugi del predstavlja vezje za filtriranje EKG signala, ki na vhod mikrokrmilnika da signal za analogno-digitalno (AD) obdelavo. Vsebuje pa razne filtre, ojačevalnike in druge čipe potrebne za merjenje. Tretji del so kapacitivni senzorji EPIC s katerimi merimo. Vsi deli se na koncu združijo v celoto in predstavljajo EKG merilnik. Filtrirane meritve se pošljejo preko bluetooth povezave na mobilno napravo z nameščenim Android operacijskim sistemom. Preko nameščene aplikacije se nam izmerjene vrednosti izrisujejo v obliki grafa. Vse skupaj pa si lahko tudi shranimo na napravo in si kasneje ponovno ogledamo. Našo EKG napravo smo testirali na različnih prostovoljcih, pri različnih aktivnostih (mirovanje, hoja in tek). Z opisano rešitvijo nam je uspešno uspelo izmeriti EKG signal. Prav tako pa smo lahko uspešno določili faze utripa pri mirovanju in hoji.

Secondary title: IMPLEMENTATION OF WIRELESS ELECTROCARDIOGRAPH WITH EPIC SENSOR
Secondary abstract: In the thesis, we have dealt with the implementation of a wireless electrocardiograph with EPIC sensors. The device itself consists of three separate parts. The first part represents the dsPIC33 microcontroller, the control of the battery and Bluetooth module. The second part presents a circuit for filtering of the ECG signal, which, to the input of a microcontroller, sends the signal for the analog-to-digital (AD) processing. It contains various filters, amplifiers and other chips needed for the measurement. The third part is the EPIC capacitive sensor, used for measuring. All parts are finally combined into a whole and represent the EKG meter. Filtered measurements are transmitted via Bluetooth to a mobile device with a running Android operating system. The application shows the measurements in form of a graph-chart. We can also save the data on the device and then later re-visit. Our ECG device was tested on a variety of volunteers in various activities (resting, walking and running). We have successfully managed to measure the ECG signal with the described solution. Also, we can successfully determine the pulse rate at resting and walking.
