Noninvasive Physiologic Sensors to Assess Depression

Wearable biosensors can play an important role in depression diagnosis. For this study, we will use a cost-effective, unobtrusive, and non-stigmatizing sensor to monitor physiological signals (including heart rate (HR), heart rate variability (HRV), electrodermal activity (EDA), physical activity, and temperature).

The X4 Device is an internally battery powered FDA-classified Type BF device used for configurable acquisition of physiological signals via EEG.

The participants will be provided with a phone app to leave audio diary recordings.

A mobile phone and tablet will be used for various purposes, including, recording of socialization, location, and activity patterns of participants and to collect emotional information based on interactive surveys, as well as for forwarding sleep and physiological sensor measurements to a secure server.
