Highly Elastic and Conductive Lamellar Wood Sponge via Cell Wall Reconfiguration Toward Smart Multifunctional Applications

Highly elastic, fatigue-resistant, and conductive lamellar wood sponges are developed via a cell wall reconfiguration strategy. The strain-induced conductivity changes in lamellar wood sponge enable tunable electromagnetic interference shielding effectiveness and high-sensitivity pressure sensing (0.72 kPa −1 ). The wood sponge exhibits a low through-plane thermal conductivity of 0.037 W m −1 K −1 , which is compression-tunable for smart thermal management.
