What countermeasures can be used against the new polygraph alternate Eye Detect?
What is effective against the Baker Digital Voice Stress Analyzer?
Not counting refusal to take test.
I'm not aware of any research into countermeasures to either technique. However, the counterinterrogation advice in Chapter 4 of The Lie Behind the Lie Detector might be helpful.

In standard polygraph chart-scoring techniques, reactions to each relevant question are compared with reactions to an adjacent "control" question, with numerical values being assigned to each reaction. In "global" scoring, the polygraph operator looks at the charts as a whole and renders an opinion. Both methodologies are highly subjective, but the latter is more so.
Note that no polygraph operator has ever demonstrated any ability to detect the kinds of countermeasures outlined in The Lie Behind the Lie Detector, and the available peer-reviewed research suggests that they can't. Note also that the late Dr. Drew Richardson's polygraph countermeasure challenge went unanswered until his death in 2016. The polygraph community's claimed ability to detect sophisticated countermeasures remains unsupported.

Anecdotal evidence about any individual's claimed ability to influence his heart rate, blood pressure, or palmar sweating is not to be relied upon.
In the peer-reviewed studies of mental countermeasures cited in The Lie Behind the Lie Detector, mental countermeasures affected polygraph chart readings (including the cardio and electrodermal channels) well enough that half of programmed "guilty" subjects given no more than half an hour of instruction succeeded in fooling the polygraph. In addition, in a secret 1995 study conducted by Department of Defense Polygraph Institute researcher Gordon H. Barland, eighty percent of programmed guilty subjects given no more than an hour of instruction on mental countermeasures succeeded in fooling the polgraph (and only five percent "failed").

The information about mental polygraph countermeasures that we provide in The Lie Behind the Lie Detector is based on peer-reviewed research that you will find cited in Chapter 4 (with article abstracts in the bibliography). None of this research describes how one is "supposed to feel" when applying such countermeasures. No mention is made of any necessary tingling sensation in the limbs or butterflies in the stomach.

- Dec 29, 2018, 11:54 PMWhen you do arithmetic or think scary thoughts or thoughts that excite you, are you supposed to feel something like a tingling sensation in your limbs or butterflies in your stomach, or does your body automatically respond even if you can't sense a great change?
