We all have our days when we forget to charge our phones, or simply exploit its battery power to the limit, and then end up offline, as it were. This is soon to become a problem of the past though, because a French telecom company, called Orange, has big plans to save us all from the low-battery blues.

Unless you have an impeccable phone charging routine, chances are you’ve been caught with a dead battery at an unfortunate moment.

Notably, this often tends to happen when there is an important task at hand. Orange has the solution: they have developed a t-shirt that uses the ubiquitous resource of noise to charge cell phones.

It’s got to do with the fabric that the shirt is made out of and it’s called a piezoelectric film which is capable of transforming sound into electricity by compressing tiny quartz crystals.

The so-called “Sound Charge” t-shirt is designed so that the electricity generated over the large surface area of the garment is stored in a battery that can then be used to charge your phone.

Luckily, the battery is removable so that the shirt can be washed.

The t-shirt made its debut during the Glastonbury music festival last month but Orange is maintaining that you don’t necessarily need to be at a loud venue for the charging to work.

Supposedly the ambient noise in a normal busy street should be enough to give a similar charging performance.

Problem is though that one shouldn’t expect this t-shirt to save you from an emergency just yet. It would still take an entire weekend at the festival to charge a universal smartphone.

Anyway, they’re working at improving the speed and efficiency of the t-shirt’s charging capability and say that this is only the first step in making the charging of electronics an automatic and effortless process.

Check out this very cool video the guys put together to demonstrate it:
