Abstract
In one embodiment, a device includes a first sheet configured to flex; a second sheet disposed below the first sheet; and an intermediate region disposed between the sheets. The intermediate region may include multiple supports, each of the supports connected to portions of the first and second sheets and configured to maintain a spacing between the sheets. The intermediate region may also include multiple channels configured to contain a fluid in the spacing between the sheets, each of the channels disposed between two or more supports. The fluid is configured to be in an active or an inactive state. When the fluid is in the inactive state, the device is substantially flexible, and when the fluid is in the active state, the device is substantially rigid.
