Tensegrity

Definition

Tensegrity is a structural design principle that utilizes a system of isolated components under compression, held together by a network of cables or tendons under tension. This unique arrangement allows for flexibility and stability, making it particularly relevant in biological systems, where it contributes to the overall integrity and function of cellular structures. The interplay between tension and compression within tensegrity structures mirrors the way cells maintain their shape and respond to mechanical forces.
