The idea: A prototype T-shirt that absorbs pressure from sound waves to charge your mobile phone.
Whose idea: Orange
Why it’s brilliant: The noise-responsive technology makes it so the louder the music, the quicker the phone charges. Sound vibrations, particularly bass frequencies, make the piezoelectric film (normally found in HiFi speakers) shake enough to produce electricity.
The shirt features a lead that fits into most phones.
