Auxetic Structure‐Assisted Triboelectric Nanogenerators for Efficient Energy Collection and Wearable Sensing

Advanced Energy Materials, Journal Year: 2024, Volume and Issue: 14(24)

Published: April 5, 2024

Abstract Triboelectric nanogenerators (TENGs) are recognized for energy conversion efficiency and applications including electronics storage devices. This study introduces a groundbreaking development in TENG by incorporating negative Poisson's ratio metamaterials to fabricate auxetic‐assisted triboelectric (Auxetic‐TENG), subversively overcoming the low power density of traditional materials. Subtly, an integrated layer‐by‐layer‐assembly core–shell accumulation strategy is employed create synclastic polytetrafluoroethylene friction shell‐skeleton, into which positive nature collagen aggregate (CA) foam inwardly embedded as core‐material. Surprisingly, on‐demand introduction synergy with CA significantly increases contact area mechanical absorption Auxetic‐TENG under pressure. enhancement electricity capitalizes on contraction origins metamaterials, expansion characteristics materials within structure, facilitating synergistic compression stratum. Consequently, achieves open‐circuit voltage 85 V, overturning four times compared conventional contact–separation TENG, 4.2 W m −2 . Application experiments demonstrate superior performance auxetic‐TENG various ratios stress conditions, highlighting its potential real‐time monitoring healthcare applications.
