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.

Oh I am well aware. That is why it is stupid to include it in the title. Having it in the body of the article makes sense, because that was their inspiration for the device. And it is true that a polygraph is capable of measuring stress when compared to an individuals baseline. Putting it in the title makes it seem like the device is going to be targeted at law enforcement/intelligence services when the device is actually meant for clinicians and other medical professionals to track stress in patients who may not otherwise be able to communicate pain and discomfort.

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