Bioelectrical signals, such as the electroencephalogram (EEG), are useful in operating rooms. It is helpful to reproduce (accurately) by the embedded systems in the operating rooms. The aim of this project is to develop is an embedded system for the reproduction of bioelectrical signals, specifically focusing on the reproduction of EEG signals. The first phase of the project is based on an investigative stage, in which information is obtained to define the appropriate design and construction criteria for the project. Consistent with this, we select amount of devices that could meet the design and construction criteria established in the previous stage. For this purpose, a low-noise analog-digital converter with SPI communication protocol is chosen. Also, a user interface is developed to select and reproduce the signals save in the embedded system. Finally, we design a stage of adequation of the signal. The embedded system is controlled by a microcontroller, ATmega 2560. The expected values for the analogdigital converter are verified using an experimental design, where the input data is changed, and the voltage at the output of the converter is measure, we obtain that the theoretical and experimental results match 99%. |
