In short: Scientists have developed an ultra slim device which can charge your phone, smartwatch and other gadgets by normal movements like walking and waving.

All this is possible by a new battery technology which is made from the layers of black phosphorus which is only a few atoms thick, when there is a slight bent or pressed even at very low frequency that a human can observe and by this the energy generating system produces small amounts of electricity which is stored.
Cary Pint, Assistant Professor, Vanderbilt University, USA said “ In the upcoming days , I expect that we all can become charging spots for our devices by generating energy from our movements/motions and the environment”
Researchers said when comparing the other approaches of producing energy with human motion this new method has 2 advantages fundamentally. i.e
The materials are atomically thin and tiny enough to be implanted into textiles while not moving the fabric's look or feel and it will extract energy from movements that are slower than ten Hertz - ten cycles per second - over the complete low-frequency window of movements like human motion, they said.
Vanderbilt University doctoral student Nitin Muralidharan said that pulling usable energy from low frequency motion has verified to be very difficult, Nitin was involved in making and testing the device.
Variety of research groups are developing energy harvesters based on piezoelectric materials that transform mechanical motions into electricity.
However, these materials typically work best at frequencies of over one hundred Hertz.
This means that they do not work for over a little fraction of any human movement so they attain limited efficiencies of below 5-10% even under optimum conditions, researchers said.
Cary Pint said, “Our harvester is calculated to control at over twenty five per cent efficiency in a perfect device configuration, and most significantly harvest energy through the entire period of even slow human motions, equivalent to sitting or standing," Pint said.

He said that one of the additional futuristic applications of this technology may be electrified clothing.
It may power garments impregnated with liquid displays that permit wearers to alter colors and patterns with a swipe on their smartphone.
Cary Pint added , ”We are already measuring performance within the ballpark for the power demand for a medium-sized low-power LCD display once scaling the performance to thickness and areas of the garments we tend to wear”
Will this technology be economically viable? It would have to be relatively cheap to be implemented in clothing etc.
Well, It's hard to say if its going to be cheap or not but as this is going to be for the general consumer I guess it would be in the mid-range in terms of price .
Wow..wonderful
Thank you :)
Wow
Thank you :)
I was just thinking about this kind of thing the other day at work.. on my feet constantly moving and a dying phone battery =)
After sometime you'll be surely using it :)
