Genius Student invented a "Mobile Airbag" case

A Germany Machatronics engineering student has invented "Mobile Airbag" case design that automatically prevent you phone when a phone is dropped.
Phillip Frenzel, a 25 years old student at Aalen University in Germany, came up with new idea after breaking his smartphone by throwing his jacket over a bannister. After this, he thought of such idea that if a smartphone of anybody fall accidentally, then it is not broken. He wanted that the case which he wanted to make, is not a big and bulky, so finally after a lot of thinking about, he invented a case that come with sensors that can detect when the phone is in free fall. It has unfolds from the corners of a relatively-thin case when sensors detect that it’s in free fall. The dampers are pushed into their “airbag” position with metal springs, and they help absorb the impact of the fall to protect a device’s screen and inner components. After being deployed, the dampers can be pushed back into the case, allowing it to be completely reusable.

Notably, the ''mobile airbag'' or AD case is currently not available for purchase yet. However, Frenzel has acquired a patent and also received an award from the German Society of Mechatronics for his invention.
