An Airbag For Your Phone, In Case You Drop Your Phone!


That moment when you drop your phone and everything stops. You can hear your heartbeat — the buzz of the world around you is silenced but now we have a way to avoid it, if you had this case on it, you’d then see it spring horns and land with a jaunty bounce.

This “active damping” case, a bit like an airbag for your phone, is the brainchild of Philip Frenzel, an engineer at Aalen University in Germany. His idea won the top award from the German Society for Mechatronics, which considered projects from students all over the country, and you can see him explain its genesis in a video here.


The Handyairbag is a relatively thin phone case that does a much better job of protecting your phone from accidental slips than most. When your phone’s in freefall, eight curled metal legs magically pop out from inside the case (think Spiderman’s spider-suit from Infinity War), curling around the front and back of your phone.

They absorb impact like springs (or an airbag, as the name suggests), as your phone bounces around without ever making contact with any surface. These curled metal ‘legs’ (for the lack of a better term) can be flattened and pushed back into the slim phone case for another day, another mishap.

The Handyairbag taps into your phone’s accelerometer, knowing when it’s in freefall and triggering protective measures the minute it senses that your phone’s falling.


There’s still a lot we don’t know, for example, would the Handyairbag accidentally trigger in your bag if you dropped it, or in your pocket if you sat down too fast (although there are workarounds, like tapping into the proximity sensor), but I’d rather have eight strange metal legs spring out in my pocket than let anything happen to my $999 phone.
