“…The following findings are the basis for the theoretical model that is proposed in this work: Fascia is a continuous three-dimensional network of connective tissue that permeates the body at various layers and depths, connects and envelops organs and muscles, while undergoing constant remodeling and exhibiting qualities of tensegrity (or bio-tensegrity) ( 4 , 6 , 8 , 9 ). According to the principle of tensegrity, structures are stabilized under conditions of continuous tension with discontinuous compression and behave as one connected structure ( 6 , 10 ). “Bio-tensegrity” applies the principles of tensegrity to our understanding of the dynamics of living organisms ( 11 ).…”

The coronavirus pandemic has led to a wave of chronic disease cases; “Long COVID-19” is recognized as a new medical entity and resembles “fibromyalgia” which, likewise, lacks a clear mechanism. Observational studies indicate that up to 30%–40% of convalescent COVID-19 patients develop chronic widespread pain and fatigue and fulfill the 2016 diagnostic criteria for “fibromyalgia.” A recent study suggested a theoretical neuro-biomechanical model (coined “Fascial Armoring”) to help explain the pathogenesis and cellular pathway of fibromyalgia, pointing toward mechanical abnormalities in connective tissue and fascia, driven by contractile myo/fibroblasts and altered extracellular matrix remodeling with downstream corresponding neurophysiological aberrations. This may help explain several of fibromyalgia’s manifestations such as pain, distribution of pain, trigger points/tender spots, hyperalgesia, chronic fatigue, cardiovascular abnormalities, metabolic abnormalities, autonomic abnormalities, small fiber neuropathy, various psychosomatic symptoms, lack of obvious inflammation, and silent imaging investigations. Pro-inflammatory and pro-fibrotic pathways provide input into this mechanism via stimulation of proto/myofibroblasts. In this hypothesis and theory paper the theoretical model of Fascial Armoring is presented to help explain the pathogenesis and manifestations of “long COVID-19” as a disease of immuno-rheumo-psycho-neurology. The model is also used to make testable experimental predictions on investigations and predict risk and relieving factors.

“…[15][16][17] The unique properties of tensegrity-based metamaterials, including lightweight design, high strength, customizability, resilience, and self-support, make them appealing for a variety of engineering applications. [18] In this paper, we employ a planar Class-2 tensegrity unit-cell made up of four bars arranged in a rhombus shape and two perpendicular cables. This type of tensegrity is commonly referred to as D-bars, [19] which are lightweight and highly scalable systems that can effectively withstand compressive loads due to their optimized structural solutions in terms of mass.…”

The interest in novel energy‐dissipation devices that offer advanced functionalities for optimal performance in state‐of‐the‐art engineering applications is growing. In this regard, a highly tunable and innovative dissipator is developed. This dissipator features movement amplification capabilities resulting from the radial replication of a unit‐cell with tensegrity architecture. The kinematic response of the dissipator is analyzed for several layouts, by varying the number of unit‐cells within the device, their internal geometry, and identifying the corresponding locking configurations. A fully operational 3D‐printed prototype is presented, demonstrating its excellent performance in terms of damping capabilities and feasibility. The experimental results are used to validate a numerical model of the flower unit. This model demonstrates the importance of pre‐strain on the overall stiffness and dissipative features of the proposed system. By utilizing these numerical models, it is shown that the proposed device can be used as a building block for more complex assemblies such as periodic metamaterials with tensegrity architecture.

“…The attention is here focused on tensegrity metamaterials which exhibit a wide range of nonlinear mechanical responses and can be suitably tuned up [17][18][19][20][21] (see also [22,23] and references therein). In particular, tensegrity-like structures are considered, which are lattices with the same nodal connectivity of corresponding tensegrities but involve no prestressed elements and thus overcome the relevant manufacturing difficulties [24,25].…”
