This smartphone casing is an attempt to protect the smartphone from impact when the device falls from a height.
In the design of the casing, the airbag is indicated by the existence of a hidden arm inside the casing that is in every corner.
The four arms are hidden and only used when a small sensor inside the casing detects the smartphone is in a free fall state. For his excellent work, Frenzel has recently received an award in the field of mechatronics from the German Society for Mechatronics.
