Development of washable biosensors for practical textile electronics

Abstract

Washability is essential for textile electronics to meet the demands of daily use. In this preview, we highlight textile-based electrochemical biosensors that incorporate moisture-resistant nanoflakes into ion-selective membranes, leading to substantially improved sensitivity and durability. These devices are integrated into a textile wristband designed for analyzing sweat biomarkers. Notably, they retain over 90% sensing capabilities for sodium, potassium, and protons even after 20 simulated washing cycles. This study marks a significant advancement toward washable and durable textile electronics for real-world applications.
