Abstract
• The structural features of wood elasticity are discussed in the context of the molecular to macroscopic scales. • Research progress is presented on the origins of wood elasticity and feasible routes to achieve its modulation. • We introduce the most recent applications of wood-based structural materials that take advantages of latent elasticity. • Biomimetic elastic materials inspired from the structural characteristics of natural wood are reviewed. The typical strength of wood makes it suitable as a structural material. Under load, natural wood exhibits a small strain within the elastic range. Such elasticity is associated with fast recovery materials, which hold relevance to applications that include piezoelectric sensors and actuators, bionic systems, soft robots and artificial muscles. Any progress to advance such advanced functions requires control on the hierarchical structure of wood as well as the multiscale and multicomponent interactions affecting its elasticity and compressibility. Herein, we review the key structural features, from the molecular to the macroscopic levels, that define wood elasticity and compressibility. They relate to the assembly pattern of wood’s lignocellulosic components, corresponding helical arrangement in the cell wall, and the anisotropy that controls the elastic and compression properties. We summarize the research progress achieved so far in the area, exploring the origins and feasible routes to modulate wood compressibility. Finally, we provide critical perspective on future impact of the area along with new applications of wood-based structures that take advantages of their latent elasticity.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
