Festival-goers can now head-bang all night long at concerts without worrying about their mobile batteries getting exhausted.
Telecom giant Orange has unveiled a prototype of a t-shirt, which uses noise-responsive technology to charge the phone. Louder the music, quicker the phone gets charged.
The futuristic garment uses an A4-size piece of piezoelectric film in a T-shirt to absorb pressure from sound waves. It converts these into an electrical charge, which it then transfers from its battery into a lead that fits most phones.
Users just need to plug their phones into the T-shirt for a quick top-up charge whenever they need it.
"Sound vibrations, particularly bass frequencies, will create enough shaking to produce electricity from a material as simple as piezoelectric film," the Daily Mail quoted Tony Andrews, co-producer of the Spirit Of 71, as saying.
"It looks like it could provide a real solution to mobile charging and I'm interested to see how the Orange Sound Charge performs in a live testing environment such as Glastonbury," he added,
Andrew Pearcey, sponsorship head at Orange UK, said: "In a vibrant festival environment such as Glastonbury, sound is such an obvious medium that it seemed like a natural fit to use it in the development of this year's prototype."
