I am an Orthopedic Surgeon with a special interest in Tensegrity biomechanics, biotensegrity.
Tensegrity is a naturally occurring construct first recognized and developed by Ken Snelson and R. Buckminster Fuller in which the compression elements of the construct 'float' in continuous tension network (example: bicycle wheel).
Tensegrity icosahedrons are used to model biologic organisms from viruses to vertebrates, their cells, systems and subsystems.
There are only tension and compression elements in tensegrity systems. There are no shears, bending moments or levers, just simple tension and compression, in a self organizing, hierarchical, load distributing, low energy consuming structure.
In other words, tensegrities are islands of compression (struts, vectors) within a continuous web of tension. The resulting forms exhibit remarkable properties such as resilience and flexibility combined with the ability to withstand dynamic stress by transferring loads to all parts of the structure simultaneously. All tensegrities are tension structures but not all tension structures are tensegrities- e.g. a spider's web relies on an external structure for support (branches etc.), and canopy architecture requires ground anchoring systems structurally similar to a spider's web.
