The concept of Kinetic Charging is known to many of us, it is used to charge many low power consuming devices such as sensors, watches and flash lights. A team of US researchers have now developed a way to charge your mobile phone by using human motion.
The device is placed in the shoe, which generates electricity by harnessing the kinetic energy of the micro droplets.”Humans, generally speaking, are very powerful energy-producing machines,” said Professor Tom Krupenkin from Wisconsin university.”While sprinting, a person can produce as much as a kilowatt of power.”
Which is more than enough to power a a standard mobile phone.
