Tensegrity

Tensegrity is a structural principle based on the use of isolated, compressed components (usually bars) distributed in a network of continuously tensioned elements (usually cables). This means that the compressed parts do not touch each other, and the tension elements are not pre-stressed. The system is in a state of self-stress, where internal forces are balanced.

The concept was popularized by R. Buckminster Fuller, though independently developed by others such as Kenneth Snelson. Fuller coined the term "tensegrity" as a portmanteau of "tensional integrity." Tensegrity structures are characterized by their lightness, strength, and ability to deform and return to their original shape. They can be found in nature, such as in biological systems like the cytoskeleton of cells.

In tensegrity, the overall stability of the structure relies on the continuous tension of the cables. If one cable is removed, the entire structure typically collapses. This principle allows for the creation of large, lightweight structures that can withstand significant forces. Applications of tensegrity can be seen in architecture, art, robotics, and biomechanics. The unique properties of tensegrity structures make them attractive for designs requiring flexibility and resilience.
