Abstract
A high-performance, low-cost modular cushion using range of novel dynamically responsive materials has been designed and developed for use in seating pressure relief. The use of individual contained spheres creates a localized area of gel to minimize both flattening under pressure, and inflating in areas without contact while the elastic nature of the polymers creates a durable system that recovers rapidly from deformation. Gel balls of varying densities have been developed to optimize performance. Quantification of individual ball mechanical properties has been completed which provides load-deflection curves to inform optimal ball array layout based on user interface pressure distributions. A fitting algorithm is proposed which will employ the patient's seating interface pressure distribution to design a personalized modular cushion layout which will evenly distribute contact pressure across seating support interface and maximize contact pressure area.
