    Helloo ,

    I want to make an advanced lie - detector .

    I have got the following ideas but dont know how to implement them :?:

    1. When a person lies , he sweats , so I can use a moisture detector.
    2. The resistance of the skin decreases due to lying ie. sweating.
    3. The pulse rate increases because of lying.
    4. The blood pressure increases .
    5. Respiration rate and depthe increases.
    6. The voice carries a pattern which is beyond the person's control. The
    stress in the voice can be sensed.

    But I dont know how to implement it ..

    Can anyone help me .. .???

    Some wine made in 2002 is pretty good.

    I would say 'yes', but I'd be lying.
