Circadian Rhythm Monitoring and Regulation Device (CMR)

DoD is concerned about circadian rhythm misalignment in military personnel as it is known to affect judgment, psychomotor skills, and may lead to or be triggered by Post-Traumatic Stress Disorder (PTSD). Correction or maintenance of circadian phase in soldiers participating in military night operations or planning for trans-meridian flights is also of interest. In addition, many veterans who suffer from chronic pain resulting from war injuries, PTSD and/or traumatic brain injury (TBI) complain of sleep disturbances that can be related to circadian disruption. To address this concern, Intelligent Automation, Inc. (IAI) and the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute are developing a modular end-to-end Circadian rhythm Monitoring and Regulation system (CMR). CMR is composed of the following subsystems: 1.DaysiWatch: A connected wrist-worn device with activity, heart rate, and skin temperature sensors and extendable to other sensing modalities such as galvanic skin response. 2. DaysiClipOn: A flexible device worn near the eye level to collect calibrated, ecological light-dark exposure patterns. 3. DaysiGoggles: Treatment goggles that provide light regulation to filter out and/or safely deliver circadian effective light as needed. 4. Smartphone with DaysiMeterApp: Software App running on the smartphone that collects data, runs simulations, controls devices and provides user feedback.
