Abstract:
Wood is a prototypical biological material, which adapts to mechanical requirements. The microarchitecture of cellulose fibrils determines mechanical properties of woody materials as well as their actuation properties based on absorption and desorption of water. This progress report argues that cellulose fiber orientation corresponds to an analog code that determines the response of wood to humidity as an active material. It gives examples for the harvesting of wood activity as well as bioinspiration.
