ABSTRACT:
In one embodiment a flexible puncture proof material for preventing a puncture by a sharp element having a pointed end includes a flexible layer for providing a flexible substrate for binding and embedding capture elements, a first plurality of capture elements for capturing the pointed end of the sharp element, the first plurality of capture elements being essentially identical and arranged in a first two dimensional array embedded in the flexible layer, a second plurality of capture elements being essentially identical and arranged in a second two dimensional array bound to and embedded in the flexible layer, the second two dimensional array offset relative to the first two dimensional array for capturing the pointed end of the sharp element if the pointed end of the sharp element passes between the first plurality of capture elements, and a third plurality of capture elements for capturing the pointed end of the sharp element, the third plurality of capture elements arranged in a third two dimensional array embedded in the flexible layer, the third two dimensional array offset relative to the first and second two dimensional array for capturing the pointed end of the sharp element if the pointed end of the sharp element passes between the first and second plurality of capture elements wherein each of the plurality of capture elements has at least one aperture large enough to accept and capture the pointed end of the sharp element and small enough to prevent the pointed end from passing through the aperture.
