A needed consideration is that testing by polygraph (also known as “truth machine”) has given rise to conflicting opinions about the scientificity of the method and regarding the validity of the outcoming results. Even if in some countries it is still used for formal questioning investigations, the idea of integrating this kind of system into a portable device best fits the social and recreative environment rather than covering any social or utility purposes.
Goal of the project is building a device from a microcontroller and few electric components, so that it has a minimum amount of accuracy needed to works in the most generic cases. This paper will cover the steps that led me to its realization.
