Biomimetics-inspired honeycomb architecture-based flexible sensors: from design to applications

Abstract

Inspired by the honeycomb structure in nature, researchers are dedicated to developing honeycomb architecture-based functional materials with excellent mechanical properties, good structural stability, and effective stress dispersion. In this review, benefiting from its unique 3D multi-scale architecture, excellent mechanical durability, and robust sensing platform, an up-to-date account of the recent advancements in biomimetic-inspired honeycomb architecture-based flexible sensors is provided for the first time. Firstly, this work systematically summarizes the basic characteristics, formation strategies, and preparation processes of flexible sensors with honeycomb architecture. Moreover, the review focuses on the latest progress of honeycomb architecture-based flexible sensors and their emerging applications. Furthermore, the challenges and opportunities of honeycomb architecture-based flexible sensors in practical applications and emerging directions are briefly discussed. This review is expected to provide a new paradigm for biomimetic-inspired honeycomb architecture-based structural materials and their emerging applications in health monitoring, flexible electronics, smart wearables, intelligent thermal management, and human–machine interaction, and promote the technological innovation and the development of materials science in related fields.
