Now shout at your smartphone to get it charged!!
Move over your normal cell phone chargers!!! Charge your cell phones with the noise created in our surroundings-which we make in ample amount.
In this era of fast paced competitive lifestyle,our cell phones does the role of our life partner with elan.So its longevity and battery capacity are very much essential for the sustainance of our new found life partner.Seems like the scientists from Queen Mary University of London and Nokia have brought a new dimension in charging our cell phones.
Scientists from Queen Mary University of London and Nokia have created an energy-harvesting prototype (a nano generator) that could be used to charge a cell phone using everyday background noise, such as traffic, music, loudspeaker and our own voices.
The team used the key properties of zinc oxide, a material whose physical properties when altered like being squashed or stretched creates a voltage by converting energy from motion into electrical energy, in the form of nanorods. These 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 are sensitive 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 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-degree C, the nanorods grew all over the surface of the sheet. Gold is traditionally used as an electrical contact but the team were able to cultivate a cheaper method of using cheap aluminium foil instead.
This ultimate setting generates five volts, which is enough to charge a phone.
Just imagine being able to charge your phone while watching cricket with your friends in a stadium or while dancing away to glory in a party without worrying your brain to find the nearest socket to charge your phone.So now folks lets make some noise and charge our phones. Whoever said making noise was bad!!!!!!
