Use Noise Pollution to Recharge Your Dying Cellphone Batteries, Researchers Claim
Cell phones always die at the worst moments and it usually seems that those moments are also the times when you can’t find places to recharge them. Fortunately, this research may allow you to recharge your phone with the power of sound. Researchers led by Dr. Sang-Woo Kim from Sungkyunkwan University in Seoul, South Korea have found a way to turn sound into electricity. No doubt, this technology will not be replacing your usual method of recharging your phone anytime soon, but it could at least help extend the life of your battery by causing less of a drain while you use it. The prototype is said to convert sound on the level of 100 decibels into electricity on the level of 50 millivolts; louder noises would create more energy. Researchers from England are also working on the same technology which helps convert noise into electricity. The device produced also is of a cell phone size and it uses sound vibration to convert into electricity with the help of zinc oxide.
