Electrochemical biosensors and power supplies for wearable health-managing textile systems

In recent years, wearable electrochemical biosensors have received increasing attention, benefiting from the growing demand for continuous monitoring for personalized medicine and point-of-care medical assistance. Incorporating electrochemical biosensing and corresponding power supply into everyday textiles could be a promising strategy for next-generation non-invasive and comfort interaction mode with healthcare. This review starts with the manufacturing and structural design of electrochemical biosensing textiles and discusses a series of wearable electrochemical biosensing textiles monitoring various biomarkers (e.g., pH, electrolytes, metabolite, and cytokines) at the molecular level. The fiber-shaped or textile-based solar cells and aqueous batteries as corresponding energy harvesting and storage devices are further introduced as a complete power supply for electrochemical biosensing textiles. Finally, we discuss the challenges and prospects relating to sensing textile systems from wearability, durability, washability, sample collection and analysis, and clinical validation. Wearable electrochemical biosensors are fostering a paradigm shift in human health management and medical practices. Textile platforms are the most promising candidates for next-generation non-invasive and comfort interaction mode with healthcare. This review explores the wearable electrochemical biosensing textile system for health management, structural design, biomarker monitoring sensors, power supply, and its future prospects. image
