CEO TECHCRIBNG (Segun Balogun) has this to say…
“As the class Governor of my department at Yaba college Of technology, It seems phone batteries always die at the same moment you need to make an important call like calling a Lecturer , before class or after class.”
While shouting at your mobile in frustration might seem pointless, a new gadget could soon mean your screams won’t be in vain. Researchers in London have created a new technology that uses sound, such as chants at a football ground or chatter in a coffee shop, to charge up mobile phones
Firstly, they developed a process whereby they could spray on the nanorod chemicals – almost like nanorod graffiti – to cover a plastic sheet in a layer of zinc oxide.
When put into a mixture of chemicals and heated to just 90°C, the nanorods grew all over the surface of the sheet.
Secondly, gold is traditionally used as an electrical contact, but the team were able to produce a method of using cheap and cheerful aluminium foil instead.
The final device is the same size as a Nokia Lumia 925 and generates five volts, which is enough to charge a phone.
‘Being able to keep mobile devices working for longer, or do away with batteries completely by tapping into the stray energy that is all around us is an exciting concept,’ said Dr Joe Briscoe from QMUL.
‘We hope that we have brought this technology closer to viability.’
