The active dampening (AD) phone case, patented by German student Philip Frenzel, is a slim alternative to bulky phone cases, but comes with a nifty trick.
So far it’s only a prototype — but the AD case can detect when the phone is falling and protract springs to make the phone bounce when it hits the ground, which should prevent any scratches or cracks on flat surfaces.
Once you pick the phone back up, you just fold the springs back in.
