A German engineering student called Philip Frenzel has invented a mobile airbag smartphone case. It could help protect phones from damage when they fall. Frenzel came up with the idea after he smashed the display of a brand new smartphone. As he was not satisfied with the bulky protective cases he used for his replacement device.

The report informs that the case is equipped with sensors that can tell when the device is in free fall. These sensors then launch four metal springs that break the fall and reduce the potential for damage to the phone. The metal springs can be folded back up into the case, ready for the next time you drop your device. You can see the case in action.

This specialized case deploys springy, spider-like legs as it starts to fall. The legs appear to soften the impact of all more than your average cage. While making less likely that the sensitive parts would collide. The student-built the sensors that detected the free-fall of the cell phone and developed a metal spring that unfolds during the fall and the power and the energy cushions the fall the report informs.

One notable advantage over airbag systems is that the device can be quickly reset by pushing the prongs back inside the case. The metal springs can be folded back up into the case, ready for the next time you drop your device.

This innovative case won an award from The German Society for Mechatronics for outstanding work in the field on mechatronics. The report informed Frenzel, is going to launch a Kickstarter campaign next month to fund the next stage of the project.
