Abstract
As mobile computing devices are increasingly expected to be smaller, thinner, and/or lighter, less space is available for incorporating such structurally stiff perimeter components, as well as energy-absorbing components. The electroactive perimeter stiffening devices, systems, and methods described herein detect a free-fall event or condition, anticipate a subsequent impact event, and actively stiffen one or more electroactive perimeter stiffeners of an associated mobile computing device in preparation for the impact event. The electroactive perimeter stiffeners direct impact energy away from, and in some cases, distribute and/or dissipate the impact energy, in an effort to prevent damage to impact-sensitive components of the mobile computing device.
