1. An impact mitigating membrane conformable to a surface of an object, comprising:
a laminar core, comprising:
a first lamina;
a second lamina configured to shift relative to the first lamina, the second lamina coupled to the first lamina at a perimeter of an aperture defined in the laminar core; and
a lubricating layer disposed between the first lamina and the second lamina and configured to reduce friction between the first lamina and the second lamina;
a first encapsulating layer positioned adjacent the first lamina;
a second encapsulating layer positioned adjacent the second lamina; and
an anchoring attachment extending through the aperture in the laminar core and coupled to at least one of the first encapsulating layer or the second encapsulating layer, the anchoring attachment configured to constrain relative lateral motion between the laminar core and at least one of the first or second encapsulating layers,
wherein the first encapsulating layer and the second encapsulating layer together surround the laminar core, and wherein the shift of the first lamina relative to the second lamina dissipates kinetic energy resulting from an impact force to the impact mitigating membrane.
