Mobile Phones: Soon To Be Powered By Walking


Like the watches and sensors, most of which are now being powered by kinetic energy, mobile phones will soon be powered by walking. This was revealed recently by the University of Wisconsin team in a published study journal on ‘Nature Communications'
‘'Humans, generally speaking, are very powerful energy-producing machines'' said Professor Tom Krupenkin from the university's Mechanical Engineering Department.
According reports, while sprinting, a person can produce as much as a kilowatt of power hence sprinting, or even walking is capable of generating enough energy to power a mobile phone. That, according to the scientist, is more than enough to power a standard mobile phone.
Although, similar methods exist for low power electronics, up until now there was no practical mechanical to electrical conversion technology that could provide such high levels of output, Prof. Krupenkin explained.
"What's been missing is the power in the watts range," said Dr Ashley Taylor, a colleague of Prof Krupenkin. "That's the power range needed for portable electronics."
