Self-Protective, Reproducible Textile Sensor with High Performance towards Human-Machine Interaction
Textile-based electronic devices have aroused considerable interests due to their excellent flexible, wearable and breathable features towards the next-generation intelligent wearable human-machine interfaces. However, as they are vulnerable to the mechanochemical attacks from sweat, oil, etc or wears and tears, the realization of functional electronic textiles (e-textiles) with simultaneous high performance, environment stability, mechanical robustness still remains a big challenge. Herein, we designed a self-protective and reproducible e-textile (SPRET) composed of entangled carbon nanotubes (CNTs) network, combined polypyrrole-polydopamine-perfluorodecyltrlethoxysilane (PPy-PDA-PFDS) polymer layer and textile substrate via a hierarchical constructing strategy. The achieved SPRET sensor can protect itself from the interference of a variety of agents with superlyophobicity, reproduce after severe machine-washing or tape-peeling cycles with mechanical robustness. In our system, the resulted wearable e-textile can be effectively conducted to monitor human motions, realize intuitive human-machine interactions and robot-learning with sweat/water exposure, showing significant potentials in practical wearable e-textiles for continuous, long-term and reliable human behavior monitoring.
