Smart clothing represents a promising technological platform for continuous and non-invasive monitoring of physiological parameters in modern healthcare, sports medicine, and remote monitoring systems. This study investigates anatomical placement challenges and technological solutions for biosensor integration in smart T-shirts. A BioSmartClothes prototype was designed and experimentally evaluated under both laboratory and on-body conditions.
The system incorporates a digital temperature sensor for body temperature monitoring, a single-channel electrocardiographic module for cardiac activity assessment, and a photoplethysmographic sensor for heart rate estimation. Biosensors were positioned based on physiological relevance and signal quality criteria, and integrated into the textile structure using conductive threads, flexible printed circuits, and printed conductive layers. Experimental results demonstrated stable and continuous acquisition of temperature, electrocardiographic, and photoplethysmographic signals for monitoring sessions of up to 60 minutes.
The findings indicate that the axillary region provides the highest stability for body temperature measurement, while electrode placement around the sternum significantly improves electrocardiographic signal quality. For photoplethysmographic measurements, mechanical fixation and optical shielding were identified as critical factors influencing signal stability. Comparative analysis of textile integration techniques revealed that hybrid integration strategies offer superior performance in terms of signal quality, mechanical robustness, and wash durability.
Overall, the proposed approach establishes a comprehensive framework for the effective integration of biosensors into smart T-shirts. The results provide a solid scientific and technological basis for the deployment of smart garments in practical health monitoring and sports performance applications.
