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.
