The ultimate effect is to decrease interface pressure and shear force by infinitesimal fluid sonic stimulation of the skin, blood medium/small vessels and capillaries and muscle tissues via: oscillating “fluid sound wave” and {HEAD ~ pressure reduction} afforded by {TAIL ~ the visco elastic material}
