Resumen

In the era of space tourism, the sustainability and efficiency of astronaut clothing are crucial due to resource limitations and the environmental impact of transporting and disposing of materials. Models were reviewed in PubMed, Scopus, Google Scholar and Science Direct using the terms Smart textile, Wearable, Space Tourism, Space Exploration, Smart T-shirt. A two-layer smart T-shirt is proposed: inner layer (Astroskin) with sensors, antibacterial properties, and UV protection; outer layer made of cotton coated with CS/PDMS and PLA for self-cleaning. It includes an ionising radiation detector (MiniPIX TPX3 Flex) connected to ESP32 with Bluetooth, photoplethysmography in the neck, integration via F-OECTs, removable sleeves with Velcro and colours white, green and blue. The T-shirt features self-cleaning, superhydrophobicity, antimicrobial activity, comfort and chromatic benefits. Astroskin, F-OECTs and external sensors monitor physiological parameters, oxygenation and ionising radiation. The detachable sleeves contribute to weight and waste reduction in microgravity. The multifunctional fabric with advanced sensors and modular design surpasses prototypes such as 3D Knitted T-shirt, 3D E-textile, Smart Textiles for Personalised Sports and Healthcare, Smart ECG Shirt, Smart T-Shirt JMIR and OncoSmartShirt, by ensuring protection, durability and comprehensive monitoring in a single system.
