Part of:


The improvement of production methods such as additive manufacturing enables us to build large volumes out of micro- and mesostructures. Being able to structure materials on this level allows us to implement novel functionality while the structures still behave like a continuum, if the distinguishable elements are much smaller than the macroscopic volume. This is often referred to as mechanical metamaterial.

Mechanical programmable materials use a stimuli-excited change in the microstructure to switch between more than one property in the same structure.

This allows to use mechanically logical elements (e.g. conditional element, materials memory, processing functions), which are implemented as mechanical mechanisms (e.g. contact, bistability) into materials.

Examples how this elements can be used to create non-homogeneous microstructures with exotic shape-morphing behavior will be shown.
