Aplikace Wifi v biomedicínském inženýrství

Abstract

The work is carried out measurements of selected biological signals with the wireless transmission of measurement data via WiFi. The implementation of wireless transmission has been selected module WiFly RN-171-XV. For measurement of the electrical activity of the heart, was designed bioaplifier one channel. Body temperature is measured with a thermistor type 10K3A1AM. Values are sampled AD converter module selected, sent to a computer where they are immediately displayed in the generated application. Wireless works in Ad-Hoc network. Electrical wiring has been implemented on a printed circuit board and encapsulated in a protective box. Connection is powered by a 9V battery. Create a software application displays the ECG waveform measurements in the chart, the temperature is displayed figure. The application allows storing data in a file type xls for further processing and analysis.
