Yelling at Your Phone Could Soon Recharge It

Scientists have devised a new gadget that will allow mobile phones to be recharged simply by talking to it. According to a report, the technology turns sound into electricity, allowing a mobile device to be charged while a conversation is in progress – and the greater the volume the greater the charge!

This new technology may come as one of the best inventions to hundreds of millions of mobile phone device users who constantly struggle with charging their devices when not close to a source allowing for this.

According to Dr Sand-Woo Kim of Sungkyunkwan University in Seoul, just as speakers transform electric signals into sound, the opposite process of turning sound into a source of electrical power is possible.

He said that sound power can be used to charge devices, like mobile phones, during conversations.

His new device uses tiny strands of Zinc oxide sandwiched between two electrodes. A sound-absorbing pad on top vibrates when sound wave hits it, causing the tiny zinc oxide wires to compress and release. This generates electrical current that can be used to charge a battery.

The power generated currently is not yet enough to charge a phone completely, but the engineers are hopeful that altering the material the wires are made from will allow them to produce more energy at lower sound levels.

While this technology is still being explored, US scientists are working on a new gadget that converts the movement of the knees while walking into electricity. According to the scientists, the knee brace harvest energy generated when someone takes a step in the forward direction.

This technology will allow commuters to charge their mobile phones while walking to and from work. The technology may also be used in battle, where soldiers will require less batteries they need while performing their duties.

However we look at it, it would appear that one day we will no longer require the conventional charger to charge our mobile devices!
