Měření a testování parametrů biopotenciálových elektrod

Abstract

The thesis deals with realization of devices for determination of parameters of biopotential electrodes. There were two ways to design and implement the device. One way was to subtract partial impedance and phase shift parameters by using the analogue connection of the tested and reference biopotential electrode. The second method of implementation was the addition of an analogue measurement scheme for digital technology using the Arduin platform, which allows to quickly and accurately measure and calculate other parameters of impedance, distortion and phase shift. All the results of this work were measured and evaluated by both analog and digital methods. The Atmel microprocessor, the master controller used by the Arduino Due platform, was used to produce the prototype. The device features a visual touch-sensitive TFT LCD display and data recording capabilities on the SD card. The result of this work is a functional sample of a test device that can analyze the important electrical properties of biopotential electrodes and evaluate the quality of the tested sensors.
