Kit de Soldadura de Detector de Mentiras Electrónico Velleman MadLab
Trabaja midiendo la respuesta galvánica
Fuente de alimentación: batería de 9 V
El Kit de Soldadura de Detector de Mentiras Electrónico Velleman funciona midiendo la respuesta galvánica. En otras palabras, cuando una persona miente, tienden a sudar. La transpiración tiene un alto contenido de sodio, por lo que el sudor es conductivo. La piel seca tiene una resistencia de aproximadamente 1 millón de ohmios, mientras que la resistencia de la piel húmeda se reduce en un factor de diez o más.
Una persona que sostenga los cables de la sonda cambiará el voltaje en el cable de la sonda superior en función de la resistencia de su piel. La resistencia de la piel está en paralelo con R2 y, debido a que es probable que sea similar o menor que R2, la tensión en el cable de la sonda disminuirá a medida que disminuya la resistencia de la piel.
