The Q Sensor looks and feels like a wristwatch, but it isn’t. It’s exactly that—a sensor. Sensing what? Thanks to a couple of silver electrodes underneath its face, it measures the wearers stress level throughout the day by sending low pulses.
Stress registers thanks to the increase in skin conductance triggered by an anxious mental state. What the Q Sensor does is collect this data so that researchers can analyze it. The Q Sensor isn’t fresh from the manufacturers though, having entered the market last year to a warm reception from the scientific community.
Developed by Waltham, Mass. based company Affectiva the Q Sensor has found a home in research labs across the U.S.A. as it’s applied to test subjects undergoing a variety of controlled situations.
The Q Sensor isn’t perfect though and is better used in a sterile environment. This flaw was discovered by writer Kristina Grifantini, who noted:
“A peak doesn’t necessarily indicate negative stress—it could reflect excitement or an artifact like a hot room. Indeed, there were some artifacts in my data—places where the stress line mysteriously drops suddenly and slowly builds back up. This usually occurs when the sensor is bumped accidentally…”
