Abstract
A first aspect of the present invention is a constant force compression construct, comprising: (a) a plurality of compressible layers, each compressible layer comprising a plurality of interconnected flexible struts configured as a regular hexagonal lattice of repeating unit cells, with the layers spaced apart from one another, and with the unit cells of each layer aligned with one another; and (b) a plurality of beams interconnecting each of the compressible layers with each respective adjacent compressible layer to form a three-dimensional lattice having an upper portion, a lower portion, and a compressible region therebetween, with the repeating unit cells contained in the compressible region.
