this isn't how polygraph works. it's just heartbeat. I'm sure that's a useful metric in detecting stress but this article is bs and the making of a "wearable polygraph" is bs as well. There are clinical heartrate monitors already avaliable.

What a waste.

The lightweight, bandage-like device gently adheres to the chest, where it simultaneously measures heart activity, breathing patterns, sweat response, blood flow and temperature. Together, these signals capture a real-time, whole-body view of stress.

If you read the article, it's not just heartbeat. Though the title comparing to a polygraph is stupid and gives the wrong impression about what the device is meant for. Polygraphs are inherently just stress detectors as well, and their use as a lie detector is pseudoscience garbage that isn't backed up by evidence.

Tracking body signals that show stress could be useful for lots of medical reasons though, so I don't think developing this device was a waste at all.

It being pseudoscience is exactly why cops and corpos want to use it so much.

And they don't even need a polygraph machine to use one.
