Researchers at the University of Massachusetts Medical School are testing a wearable device that may help track drug addiction relapses.
The E4 Empatica wristband device measures temperature, heartbeat, motion and skin electrical conductance, according to Business Insider. The measurements are taken 30 times per second.
Knowing the time addicts tend to relapse, and the effect the relapse has on their bodies, can help doctors improve their methods of intervention, according to researcher Stephanie Carreiro. She has led two studies on the device.
