Dynamic Network‑ and Microcellular Architecture‑Driven Biomass Elastomer toward Sustainable and Versatile Soft Electronics
Biomass-derived conductive elastomer featuring dynamic networks and microporous architecture enables ultralight and highly mechanosensitive soft electronics.Micro-spring-like porous structure imparts excellent stretchability, superior resilience, and rapid and precise electrical responsiveness under subtle and large mechanical stimuli.Intrinsic dynamic interactions enable efficient room temperature self-healing and full recyclability, promoting sustainable and scalable fabrication of advanced fl Credit: Shanqiu Liu*, Yi Shen, Yizhen Li, Yunjie Mo, Enze Yu, Taotao Ge, Ping Li*, Jingguo Li*.

Soft sensors that feel gentle taps yet survive 500 % stretch still rely on petro-based rubbers and energy-intense foaming. A ZJUT–USTC–Xi’an Jiaotong team led by Prof. Shanqiu Liu and Prof. Jingguo Li now twists lipoic-acid chemistry into an ultralight (~0.25 g cm -3 ) biomass conductive elastomer that self-foams at room temperature under 2 MPa CO 2 , heals in 5 h and recycles five times without property loss. The resulting “micro-spring” lattice delivers a gauge factor of 4.8 under 1 % strain, rebounds 93 % after 200 % pull and tracks handwriting, heartbeat and ball drops in real time.

Why This Matters

Innovative Design & Features

Applications & Future Outlook

By marrying a biomass backbone with CO 2 -blown micro-springs, the work offers a production-ready route to sensing foams that are light, tough, healable and endlessly reusable—pointing toward truly sustainable soft electronics that can be worn, folded, recycled and reborn.
