The emerging technology will help the Smartphones get charged from voice. Mobile phones could be charged using traffic noise, music, and even your sound.
In coming day’s it is possible to charge your mobile phone by traffic noise, music, and even your own voice! Yes guys its true, you can charge your mobile phone from voice.
Scientists from Queen Mary University of London and Nokia have created an energy-harvesting prototype that could be used to charge a cell phone using everyday background noise such as traffic, music and our own voices.
The scientists is working to develop a prototype charger that could replenish the battery of a mobile phone using human voices, music or even background noise. 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. They used the key properties of zinc oxide, a material that when squashed or stretched creates a voltage by converting energy from motion into electrical energy, in the form of nanorods.
The nanorods can be coated onto various surfaces in different locations making the energy harvesting quite versatile. When this surface is squashed or stretched, the nanorods then generate a high voltage.
The nanorods respond to vibration and movement created by everyday sound, such as our voices. Electrical contacts on both sides of the rods are then used to harvest the voltage to charge a phone. Researchers first developed a process whereby they could spray on the nanorods 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 degrees 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 auminium foil instead. The ultimate device generates five volts, which is enough to charge a phone.

I know charging phones this way could be a part of the future, but there probably isn’t enough energy in voice to remove the need for conventional charging completely. It could help to reduce how often we need to charge our phones, though. Transforming sound in to battery is not a easy task. We first heard of a voice-charging mobile phone that would power itself with user’s voice when a team of korean researchers revealed their prototype in 2011. Now that engineers have partnered with a communications technology corporation, it seems much more likely that a voice-powered charger may soon be a reality.
So, you can listen music or play video in the loudspeaker in the Smartphone without fearing the battery charge. Its really a wonderful technology. Hope this amazing technology will come soon.
