Beim Glastonbury Festival 2011 wurden zum ersten mal die “Sound Charge” Shirts getestet. Die vom Mobilfunkanbieter Orange produzierten Shirts greifen die Schallwellen auf und produzieren auf diesem Wege Energie um das entladene Smartphone aufzuladen.
Eigentlich wäre dieses Projekt doch auch wunderbar auf den Straßenverkehr zu übertragen, oder liebe Forscher?
“The eco charging device uses an existing technology in a revolutionary way; by reversing the use of a product called Piezoelectric film, allowing people to charge their mobile phones whilst enjoying their favourite headline act at Glastonbury. Usually found in modern hi-fi speakers, an A4 panel of the modified film is housed inside a t-shirt which then acts much like an oversized microphone by ‘absorbing’ invisible sound pressure waves. These sound waves are converted via the compression of interlaced quartz crystals into an electrical charge, which is fed into an integral reservoir battery that in turn charges most makes and models of mobile phone. As the ‘device’ is worn, a steady charge is able to be dispensed into the phone via a simple interchangeable lead which fits most handsets.”
