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.

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 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.
