Stemmetallene
Stemmetallene are a class of metallic alloys developed for biomimetic plant-stem applications. The term, rooted in the idea of stem-like biological structures, is used in materials science, soft robotics, and experimental biomechanics to describe lightweight alloys whose stiffness, strength, and damping can be tuned to resemble living stems.
Properties of stemmetallene are defined by high specific strength, adjustable axial stiffness, and good energy absorption.
Composition and production typically rely on aluminum-based bases, such as Al-Mg-Si alloys, with small additions (for
Applications of stemmetallene span surrogate stems in plant biomechanics experiments, lightweight structural members in robotic and
History and nomenclature note that the concept emerged in early 21st-century biomimetics research, with several laboratories
