Energy storage elements in or under shoes or on or as a modular prosthetic foot replacement

Abstract

The invention relates to the field of materials science and concerns energy storage elements in or under shoes or on or as a modular prosthetic foot replacement. The object of the present invention is therefore to provide energy storage elements that significantly reduce or even prevent neuromuscular fatigue.The problem is solved by energy storage elements consisting of at least two leaf springs or leaf-like structures, between which there is a gap, and which may or may not be connected to each other in the forefoot area, and which may have further leaf springs or leaf-like structures in the rearfoot area, or in the rearfoot area where one leaf spring or leaf-like structure may pass through the other leaf spring or leaf-like structure, and above the upper leaf spring or leaf-like structure an insole is arranged, and open and / or closed spaces are present between and around the leaf springs or leaf-like structures, which are filled with air or with a material for damping and / or energy storage.
