Battery-powered products are prominent in today’s age, but that power has to come from somewhere. Eventually, you’ll have to charge that battery for your cell phone, laptop, or whichever product you’re happening to use. Tired of having to be near a charger when battery-life is low? You’re in luck.
A group of Korean scientists, led by Young Jun Park and Sang-Woo Kim, are currently researching ways to turn sound into a power-source. For example, a cell phone battery with sound-power capabilities will continue to charge just by having the consumer continue their call.
Their full report appears on an article in the Advanced Materials journal.
Sound-power technology isn’t out yet, but aftermarket rechargeable batteries can still be found.
