Scientists have demonstrated that skin conductance can help measure our core emotions. It's only a matter of time before EDA sensors on wearables implement it.
Over the past few years, the wearable segment has seen rapid advancement. We now have smartwatches capable of everything from ECG and blood pressure analysis to sleep apnea detection and stress monitoring. One day, they could gauge our emotions, too.
“When people feel different things, the electrical properties of their skin change drastically due to perspiration, with signals showing up within one to three seconds of the original stimulus,” the team explains. The variations in skin conductance were measured using probes attached to their fingers.
Do keep in mind that the human emotional spectrum is much wider than just fear, sadness, and fun, so there’s that uncharted scientific territory left unexplored, as well. However, the researchers note that the skin conductance data could prove useful in making “ statistically significant predictions of whether a subject was experiencing fear or feeling the warmth of a family bond.”
