Digital Lie detector measuring respiratory rate

[billymas]

hi all,
i would like know any idea of building a digital lie detector whic measure human respiratory rate,which can show & store the data in pc.....
if possible,can pls send me the schematics please?
any opinion is appreciated

If you have a any idea of building a perpetual motion circuit that actually works could you please send me the schematic? It will make me a lot of money.

I don't think they even use respiration. Galvanic skin response, blood pressure, and pulse rate are far more important.

Heads or tails.
Some people breath faster when they lie.
Other people take a deep breathe then breathe slower when they lie.
Some people don't produce any difference in their breathing when they lie.

It works only with my dog. She lies a lot then breathes quickly when she gets too hot.

Can you send me a copy too please.

No because I'll copyright the schematic and pattent the idea.

Sell me one at a discount?

sory,i hv given wrong statement d,
it's suppose to measure human's pulse rate/ECG......

I can design around it. Just give me the basis. If I can't, good lucking litigating

That is a lot different than the respiration rate.

My pulse rate slows when I lie. My wife's speeds up. Who is lieing?
