En el presente trabajo se diseñó el hardware electrónico de los bloques funcionales que componen un estimulador eléctrico transcraneal. Se programaron las tareas que debe desempeñar el microcontrolador que administra dichos bloques funcionales de manera que estos operen armónicamente. Se comprobó que el estimulador desarrollado es capaz de entregar pulsos rectangulares con amplitud de voltaje de hasta 1000 V e intensidad de corriente de 1 A, con errores inferiores al 5 % respecto a los valores teóricos esperados de todos los parámetros físicos medidos. El sistema diseñado inhibió la generación de estímulos ante la detección de un evento potencialmente peligroso. Estos resultados evidencian que los estímulos generados se corresponden con las características del equipo propuesto.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT The transcranial electrical stimulators are medical equipment (or part of medical equipment) used in surgical acts that put at risk the motor nerve pathways to monitor the structural and functional state of these nerves. In the present work we designed the electronic hardware of the functional blocks that make up a transcranial electrical stimulator. The relative tasks to the microcontroller were programmed. The developed stimulator is capable of delivering rectangular pulses with a voltage amplitude of up to 1000 V and current intensity of 1 A, with errors lower than 5 % regarding the theoretical values. The actuator system inhibited the generation of stimuli when detecting of a potentially dangerous event. These results show that the generated stimuli correspond to the proposed equipment characteristics.]]></p></abstract>
