This study had the following specific aims:
Participants completed a survey on their iPads after each day they wore the Astroskin. Personnel at the HERA facility provided crews with an open network port allowing them to connect to the survey website from within the habitat. Survey data were stored on a Qualtrics secure server and downloaded by the investigator after each mission day. The survey included three categories of questions: 10 questions on garment and headband comfort; 5 questions on interference or impact on performance of activities; and 12 questions pertaining to operations of the garment and plug-in device. The questions consisted of four fixed choice responses on an ordinal scale measuring levels of agreement/disagreement (e.g., very comfortable to very uncomfortable).
Investigators discovered that real-time data streaming via Bluetooth to an onboard mobile device significantly reduces battery life resulting in less than 24-hour recordings and that current software for real-time data streaming does not store data on the mobile device. In addition, the inability to view streaming data is a risk to studies in the analog environment and may result in signal loss or poor signal quality.
The current prototype garment design is less than optimal for female crew which resulted in movement of ECG sensors and poorer signal quality. The ability to wash the garment is a potential issue for extended duration missions requiring cleaning options or stowage of multiple garments. Participants experienced significant discomfort after wearing the headband sensor when worn for 24 hour periods. Real-time data streaming requires higher capacity battery and/or lower power Bluetooth transmitter. The analog setting helped investigators to better understand some constraints and requirements related to the design and use of a biomonitoring system (e.g., interference from other equipment). Crew input from the surveys provided useful insights on how to improve the garment design.
