Philip Frenzel, an ambitious engineering student, has invented a “mobile airbag” which deploys when your device is dropped. Frenzel’s design begins with a thin protective case, outfitted with sensors that detect the free fall of a phone. Once airborne, metal springs deploy to cushion the fall. You can then push the attachments back into the case and reuse when necessary. For more on Frenzel’s innovation: https://www.pre-view-online.com
