Unstable and mechanically demanding habitats like wind-exposed open fields or the wave-swept intertidal require rapid adaptive processes to ensure survival. The mechanism of passive reconfiguration…
Process Sequences In Biomimetic Research
The presented methodology of doing biomimetics has proven effective in many R&D projects and two principally different approaches can be distinguished as ‘bottom-up process’ and ‘top-down process”.
Insulation capability of the bark of trees with different fire adaptation

Video recordings proved that A. donax becomes streamlined with increasing wind speed, reducing the projected surface area of leaves and stem, which is a potentially important adaptation for withstanding high wind loads, especially for individual plants and plants at the edge of stands.

To illustrate, the oscillation frequencies of 25 spruce trees were compared with those calculated on the basis of their morphology, their density and their static elasticity modulus, which was compared with that determined in three-point bending.

The objective of this paper is to rationalize and refine the discussion about bio-derived developments also with respect to sustainability by taking descriptive, normative and emotional aspects into consideration.
An Overview of Bioinspired and Biomimetic Self-Repairing Materials
The current overview presents a selection of breakthroughs regarding bioinspired or biomimetic self-repairing materials, including the initial basic publications and the recent publications of the last eight years.
Sustainability assessment of a lightweight biomimetic ceiling structure

Technological advancement culminating in a globalized economy has brought tremendous improvements for mankind in manifold respects but comes at the cost of alienation from nature. Human activities…
Mechanical Properties of the Rhizome of Arundo donax L.
Morphological and anatomical examinations suggest that the mechanical anisotropy of the stem is caused by the arrangement parallel to the stem of the vascular bundles and sclerenchymatous fibres, embedded in lignified parenchyma.
