The space environment, with its microgravity, radiation exposure, and extreme temperature variations, poses complex health risks to crew members.

The Power of Flexible Wearable Health Surveillance Systems

Flexible wearable systems, equipped with multimodal sensor arrays, enable comprehensive and continuous health surveillance. These integrated platforms include inertial measurement units, biosignal electrodes, and environmental detectors, among others.

They have proven to be indispensable for early anomaly detection in cardiopulmonary functions, neuromuscular performance, and circadian rhythm regulation, thereby facilitating timely personalized countermeasures.

Nonetheless, despite recent advancements in materials science and miniaturized electronics, three notable technical barriers persist:

1. device reliability under combined space stressors
2. secure data management protocols addressing confined spacecraft privacy concerns
3. multi-parametric data fusion challenges involving temporal-spatial synchronization of heterogeneous bio-signals.

These research areas will cover advanced materials science, new materials and sensor technology, intelligent algorithms, data processing and device integration.

Interestingly, the development of technologies in the field will still rely on material innovation, the creation of intelligent algorithms, the improvement of user experience and interdisciplinary cooperation.

In particular, continuous development and maturity of the technology, together with flexible electronic devices, will play an important role in enhancing astronauts' health monitoring capabilities and promoting the progress of human space exploration in the future.
