摘要：
Embodiments of the present disclosure relate generally to variable stiffness devices, including orthoses, that use the principles of granular jamming. In some embodiments, a device may comprise a cell having an air impermeable outer bladder. The outer bladder of the cell can define an internal pocket. A plurality of granular particulates may be disposed within the first cell. The stiffness of the cell can be altered by altering the negative internal pressure of the cell, thereby causing the granular particulates to compact, or jam. In some embodiments, a plurality of cells may be disposed within a device. The location of each of the plurality of cells may correspond to a location of a user's foot. The mechanical characteristics of each cell of the plurality of cells may be independently adjusted by adjusting the negative internal pressure of the cell.
