Not really.
Mostly they are only useful as a form of pressured interrogation, where the stress of being hooked up to the supposed "lie detector" (hah! don't make me laugh) tends to make people screw up their story or lose their nerve and confess.
That springy band across your chest? It isn't even hooked up to anything.

'I hate the Dallas Cowboys' *machine reacts strongly*

Two huge problems though.
1) The degree they work and under what conditions vary considerably and can't be predicted.
2) The techniques to beat a polygraph are not very complicated.
They can prove you have a stress reaction when answering a question, whether that means you're lying, emotional, or doing it intentionally is up for someone else to interpret.

They work fine unless the respondent knows what s/he's doing.
