Monitoring multiple vital sign parameters over a prolonged period of time is not possible with other currently available wearable products. Compared to Astroskin, or other commercial products, the OAWSS offers a solution that allows exploration of a different operational mode. The dissemination, management and storage of data vary from other wearables created for space flight monitoring by: 1) the fully wireless nature of the technology; 2) the dynamic and flexible user interface; 3) the capability to acquire data continuously (up to one week without interruption); and 4) the possibility of adding additional sensors (plug-and-play) since there is no physical connection with the data acquisition module.
This experiment has the following aims:
Phase 1 of the research will be carried out at ARC using 8 male and female participants. These 8 participants will undergo 3 days of laboratory testing to assess the functionality of the OAWSS: submaximal ergometer and rowing exercise on days 1 and 2; and a standard rotating chair test designed to elicit motion sickness symptoms on day 3. Research subjects will wear the OAWSS biosensors continuously for 48 hours off-site to collect biometric data and evaluate user comfort and functionality of the biosensors. In addition to OAWSS sensors, standard lab devices (Equivital harness and Empatica E4) will be worn by participants and these data will provide reference measures for comparison.
Phase 2 of the study will be conducted at JSC using another 8 male and female research participants. For these tests, participants will wear the OAWSS, Equivital harness and Empatica E4 while they perform a flight-like cycle ergometer protocol, and a self-pacing treadmill test with various inclines to simulate climbing up a hill to deploy a communication device and climbing back down the hill. During this task participants will wear a weighted suit with an additional 40% of their body weight to simulate interference experienced by the space suit. The purpose of the data collection in these conditions is to evaluate functionality and interference of the OAWSS in response to physical exercise and a simulated Lunar or Mars exploration task.
This experiment is currently in progress. Results will be made available at a later date.
