Wearable Sensing

The use of body-worn devices such as smartwatches, wristbands, and biosensor patches to continuously monitor physiological signals including heart rate, electrodermal activity, skin temperature, blood volume pulse, and body movement. In mental health applications, wearable sensing can detect stress, anxiety, and behavioral patterns associated with conditions like OCD, enabling just-in-time interventions when elevated distress or compulsive behaviors are detected. Challenges include sensor accuracy, battery life, social acceptability, and the difficulty of distinguishing OCD-related behaviors from normal activities.
