The development in textile technology has led to electrodes and wearable measuring systems. For the implementation of wearable systems is necessary to characterize properly the electrodes and its influence in generating measurements. The validation of the performance of textiles electrodes must be made with real ECG measurements. To obtain this ECG with textiles electrodes, a system must be implemented. This system should integrate an ECG amplifier, an USB DAQ system, the obtained data is received by a Labview application which stored this data in an ASCII text file. This text file is used to subsequent study in a power analytical application, for example, Matlab.
