摘要

The trend towards progressively more portable and wearable strain sensors has led to rapid advancement in full-range human-health diagnostics. However, developing sensing materials with long-term durability and lifetime, while maintaining high sensitivity and large working range, remains a grand challenge. Herein, we design a printable nanocomposite with nacre-inspired hierarchical structure, diffusible components and abundant dynamic interactions for the construction of healable and durable strain sensor. In contrast to conventional hydrogel and elastomer-based healable sensing materials, this nanocomposite can simultaneously exhibit gauge factor > 100 over full range of working strains up to 52% and demonstrate an ultrahigh gauge factor exceeding 3500 in the strain region of 38 - 52%. This strain sensor can repeatedly and effectively self-heal with simple water treatment, greatly expanding its lifespan and cycling durability (over 10,000 cycles). The healed device can completely restore its sensing ability for precise full-range human-body monitoring. Our strategy represents a critical step in the continual development of wearable electronics.
