Reveal is a wearable band which aims to help kids on the autism spectrum track anxiety stressors.
The band works by measuring three major indicators of anxiety — heart rate, temperature and electrodermal activity (also known as “emotional sweat”) — through a pair of electrodes embedded in the band. Those signals are transmitted to the Reveal smartphone app, notifying parents and caretakers of impending “behavior meltdowns,” so preventative measures can be taken. Caregivers can also add contextual data to help the app develop a complete profile of the child.
