Charger
Problems Resolved
With the new discoveries and advancements in
technologies, gadgets are to be found here and there. And because of the
pleasure we can get from these gadgets, many of us are spending number of hours
using these gadgets. While we are enjoying listening to the music, playing
games, having some selfies, and surfing the internet, isn’t it annoying that
your cell phones for example will just shut down because the battery is already
drained? And it’ll really a big problem if you’re in the middle of a walk or a
trip and you haven’t brought your charger with you. Sometimes, it’s also a
trouble searching for sockets especially when you’re not at home or at office.
So, with the help of Goergia Tech researchers lead by Zhong Lin Wang, this nuisance
of ours is already answered - these researchers invented a charger that will
get the electricity it needed from your body motion.
“The device — built by Georgia Tech
researchers, led by Zhong Lin Wang — consists of four discs layered on top of
one another. The first disc is made of copper, and rotates. The next is a
polymer and remains stationary, and the third is a
gold layer that is divided
into sectors, with alternating sections cut out, to make something that looks
like a bicycle wheel. The last layer is made of acrylic.
When the copper disc rotates, positive
charges in the copper move past the negative charges in the polymer. That
causes an imbalance of charges in the gold layer, with each "spoke"
of gold having either more positive or more negative charges. This imbalance
means that when a wire is connected between sectors, current flows. Wang said the device can generate power as long as
something causes the copper disc to rotate...” (Live Science)
This device is indeed so efficient
for us that it comes in wearable versions and is about 4inches across. During
ordinary days, you can attach this device on your hands or leg while walking or
jogging and it can already generate about 5volts of electricity. It will really
be useful for everyone, say for example those having some fieldworks and to
those who are in a place with a very limited amount of electricity. In an
emergency like during brownouts too, this device will be of great help in
keeping our gadgets on for us to have a continued communication. The fact that
different gadgets like smart phones have been already a part of everyone’s
everyday life – used in communication, for entertainment, to acquire
information or news details, etc., this new discovery really comes in handy.
New problems arise as new gadgets
are also discovered. But the good thing is that, people never stop searching
answers and solutions for man’s convenience.
