Is there any way to catch a liar?

Like hypnotism?

Or reading micro-expression?

Or truth-serum?

I think that this is a bit of a silly question but I just wanted to know. I think the ones mentioned above are either illegal, not possible, a myth or not very effective. My question is are there any similar techniques or instruments other than good old cross examination and lie-detectors. I ask because I had no knowledge of reading micro-expressions until recently.
