The relationship between geometry and stability in a tensegrity system can be easily explained using a simile: the balloon analogy.

Of great importance is the stability of the structure, once assembled. The stability condition implies that the structure returns to its original shape after the release of a small forced deformation[4]​[5]​.

In the mid-70s, Donald Ingber proposed a hypothesis in which he related tensegrity structures to the mechanical behavior of cells. To check this, model a structure composed of six bars joined with elastic threads. When placed on a rigid surface it tends to adopt a flattened shape, while on a flexible surface it stands up showing a more rounded conformation. This behavior was consistent with that observed in cells when they were deposited on the same type of surfaces. Ingber concluded that, from a mechanical point of view, the cell could be considered a tensegrity system.

Discoveries in biology confirmed this hypothesis when, in the early 1980s, Keith R. Porter managed to reveal a three-dimensional network of filaments inside cells: the cytoskeleton, which would have the same role as bars and cables in tensegrity structures: balance the efforts that would give shape and rigidity to the cell.

The advantages of tensegrity structures are:

The drawbacks of tensegrity structures are:

The most basic tensegrity structure is known as the Simplex structure. It consists of 6 nodes, which are joined by 3 compression elements (bars) and 9 tension elements (cables).

Let's see the steps necessary for its construction:.

A more complex structure made up of Simplex elementary structures can be formed, as can be seen in the figure, by sharing one of the vertices and one of the oblique tensile elements. This type of union is known as a Type Ia union.
