Resumen


Electrical stimuli are generally used for obtain evoked potentials, that are useful in medical research. To perform the stimulation is necessary to have equipment capable of generating various waveforms. In this paper a programmable electro-stimulator to generate pulse waveforms.  This is accomplished with a simple design with few resources and appropriate parameters for use in laboratory animals. It achieves a low error in the stimulation current, despite possible changes in the electrode impedance. Shows the structure of the stimulator designed and functions of the main blocks. Finally, we present the records obtained in experiments with laboratory animals.
