IMPACT RESISTANT DEVICE COMPRISING AN OPTICAL LAYER

摘要

An impact resistant device includes an optical layer and electronics. The optical layer and electronics are comprised in a flexible foil structure which is supported by a backing structure in mechanical contact on a backside of the flexible foil structure. The backing structure includes a deformable material having a viscous response in a critical range, which critical range is defined for a given front impact event by a pressure threshold (&sgr;critical) and a stretching threshold (&egr;critical) of the flexible foil structure such that the optical layer and/or electronics are not damaged by the impact event.
