Engineers have shown a new product they connect with ‘nanocardboard,’ an ultrathin equivalent of corrugated paper cardboard. A sq. centimeter of nanocardboard weighs considerably less than a thousandth of a gram and can spring again into condition right after remaining bent in 50 %. Nanocardboard’s stiffness-to-body weight ratio tends to make it suitable for aerospace and microrobotic purposes, in which every gram counts.
