mikroaskelten

Mikroaskelten, literally the “micro skeleton,” is a term used across disciplines to describe a structural network at the micrometer scale that provides shape, support, and mechanical integrity. The term is not tied to a single technology or material, but rather serves as an umbrella for micro-scale frame-like architectures found in natural systems and engineered materials.

In biology, the closest equivalent is the cytoskeleton, a dynamic ensemble of actin filaments, microtubules, and intermediate filaments that organizes the cell interior, enables movement, and mediates mechanical responses. At the micro level, these networks determine cell shape, stiffness, and the transmission of forces through the cell. The concept of mikroaskelten in this context highlights how tiny structural elements collectively produce macroscopic mechanical behaviors.

In materials science and engineering, mikroaskelten refers to designed micro-lattice or porous skeletons that provide stiffness and strength while keeping weight low. Such structures are used in light-weight engineering, impact absorption, and bone-substitute scaffolds. Common fabrication methods include additive manufacturing (3D printing), micro-lithography, and electrospinning, which enable precise control over geometry, porosity, and anisotropy. Properties of mikroaskelten structures include tunable stiffness, energy absorption, and tailor-made thermal or acoustic responses.

Applications span medicine, where micro-architectured scaffolds support tissue growth, to aerospace, automotive, and protective equipment, where lightweight, robust lattices improve performance. The concept is inherently interdisciplinary, blending biology-inspired design with advanced manufacturing to create scalable micro-scale frameworks.

Terminology varies by field, and mikroaskelten is best understood as a general descriptor for micro-scale skeletons rather than a single standardized technology. See also cytoskeleton, micro-lattices, metamaterials, and scaffolds.
