Aims:

Currently in spaceflight, crewmembers report their sleep duration as requested by their crew surgeon. This approach has several limitations, including the burden it places on the crew and the tendency for subjective over-reporting of sleep (Lauderdale et al., 2008; Van Den Berg et al., 2008; Silva et al., 2007). Given evidence that demonstrates the relationship between sleep and circadian phase and performance, sleep-activity data should be collected as unobtrusively possible during long duration spaceflight. Wrist-worn actigraphy has been implemented as a successful, validated research tool in spaceflight but lacks features to render it a useful tool operationally, such as real-time feedback and minimal crew time requirements. Hence, there is a need for a minimally obtrusive or unobtrusive measure that evaluates sleep-wake activity plus light exposure; is acceptable for continuous wear; minimizes crew time by allowing for automatic downloads; provides immediate feedback to the user; incorporates the constraints of spaceflight hardware, such as extended battery life; and potentially incorporates other features, including other physiological sensors.

SBIR Phase II: The purpose of this task is to test and validate refined technologies so that they serve as an objective measure of sleep-wake activity (and lighting) while fitting into the spaceflight mission environment.

The Technical Objectives of the Phase II project are:

1.) Conduct user testing to achieve initial product validation in a space analog environment and guide Phase II product refinement.

2.) Develop an updated version of STARwatch tailored to meet the exact needs of space exploration.

3.) Develop state-of-the-art sensing and advanced analytics features to support space exploration missions.

4.) Conduct user testing with the updated version of STARwatch to validate updated features and prepare for transition to space flight.

Three SBIR 2014 Phase I projects were previously completed for the topic of Objective Sleep Measures for Spaceflight Operations:

1.) Wearable Device for Objective Sleep Monitoring [awarded to Linea Research Corporation]

2.) STARwatch to Deliver Objective Sleep Measures for Spaceflight Operations [awarded to Pulsar Informatics, Inc.]

3.) Circadian Rhythm Management System [awarded to Orbital Research, Inc.]

Category: Technology or Tool
Subcategory: Systems Solutions, Prototype Hardware or Software

Description:
SBIR Phase II: This monitoring technology provides an objective measure of sleep-wake activity and an assessment of sleep stages, providing crewmembers and medical operations real-time data related to sleep and activity levels so that risk can be mitigated. A previous Actiwatch technology was not adopted as part of operations owing to the crew time requirement. This task contributes to gap closure by yielding a validated, minimally obtrusive tool that reduces human resource constraints (such as crew time) and will be feasible in the spaceflight environment.
