The circuit is just a simple ohm-meter. Use a multimeter set to volts or mA as its display.
A multimeter has a better ohm-meter. Then you don't need this simple circuit.

A person is not static charged. But if the air is dry, the person is insulated from ground and combs his very dry hair or removes a very dry sweater then he can become static charged until he touches something that is grounded.

I had some shoes with synthetic (plastic) soles. At work the carpet was synthetic (plastic). My shoes and the carpet were very good insulators and in winter the air was very dry. When I shuffled my shoes on the carpet as I walked I developed a very high static voltage and I zapped anybody who came near me. A long spark jumped from my finger and the telephone system would reset. I got leather soled shoes and the static stopped.

We talk about electronic circuits here, not physics.

The lie detector circuit is a simple ohm-meter. Some people (not everybody) sweat when they say a lie. The sweat reduces their skin's resistance and the ohm-meter shows it.
Then add 2 more pages of blah, blah, blah etc.

Look at Lie Detector in Google. There are many other things to sense plus a lot of experience reading them to guess that a person is saying a lie.
