SCIENTIST INVENTS SHOE THAT CHRAGES YOUR PHONE AS YOU WALK
« on: December 29, 2014, 05:32:21 PM »


Ex-students of Carnegie Mellon University, Pennsylvania has invented a Shoe
that generates enough power to charge phones while walking

Sounds cool isn't?  ;)
Checkout the image below



How does the Shoe generates power while walking?

The insoles fit into shoes and the wire is wrapped through the laces.

The charging wire from the insole is plugged into the battery pack, which sits outside the shoe - either fastened
around the ankle, orclipped onto the top of the footwear.

An embedded mechanical system inside the soles generates the electricity.

During the heel strike of each step, kinetic energy of the foot is transferred into the mechanical system.

This uses the energy to spin a micro-generator. Wearers walk for an hour to generate two-and-a-half hours’ worth
of power for a smartphone.

When the battery pack is charged, it can be unclipped from the shoe and connected to a smartphone, or other device using a USB cable.
The device is set to go on sale soon.



The insole connects to a power pack (pictured) and collects kinetic energy, with a mechanism that converts linear motion - generated while walking - into rotational motion, which is capable of spinning a generator



The generator allows power to be built up in an external battery pack connected by a cable, called a PowerPac (shown right). This PowerPac is tied onto the laces so it sits on top of a shoe. It contains a USB port, allowing a variety of items to charge off it, including smartphone (illustrated left)
