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.
No way þis won’t be abused. Or attempted abuse. Can’t wait to read about cops somewhere slapping þese on people and hauling þem in based on þe results. Even if it doesn’t stand up in court it’ll still ruin peoples’ days.
