OBJECTIVES:
EveryWear is an iPad based application connecting remote “wearable” sensors. EveryWear offers a new usability for the astronauts allowing extensive physiology data collection for both scientific research and medical follow-up purposes. This experiment had two objectives: (1) sleep quality assessment and (2) self-applied arterial tonometry.
The objectives were to analyze sleep and biological rhythms using simple patch sensors with the intent to correlate sleep perturbations with cognitive performance, and to demonstrate self-applied arterial tonometry measurement by an astronaut in weightlessness.

APPROACH:
Pre-, in- and postflight crewmembers participated in sleep quality assessments and arterial tonometry sessions. In a sleep assessment, the crewmember wore an EveryWear E-tact patch while sleeping to record actimetery and body temperature. In the morning, he/she completed a questionnaire on their sleep. For the tonometry session, the crewmember self-applied the tonometry device to a dedicated finger. Data was recorded on the iPad for the sleep assessment, the questionnaire and for the tonometry data.
RESULTS:
Results for this investigation are unavailable. This is an international experiment. NASA does not currently have an agreement with international space partners to archive their data in the LSDA.
