Now, charge phone battery by playing music at it
Washington: Scientists have created a prototype panel capable of charging a cellphone off environmental vibrations like music or dinner conversation.
Scientists from the Queen Mary University of London have developed a device called "nanogenerator", which is made of plastic sprayed with a sheet of tiny zinc oxide rods that generate electricity when squashed or stretched, thus building an alternative power sources for your cellphone.
The research team, in partnership with Nokia, said that these sheets can be produced cheaply and generate five volts of electricity, the same as most phone wall chargers.
They added that traffic, music, and voices are some of the things that could help charge the battery.
