Two 15-year-old school boys have developed a device that will enable a shoe to charge a mobile phone while walking. Anand Gangadharan and Mohak Bhalla, both students of south Delhi’s Mount Carmel school, have invented a compact attachment, which, when attached to the heel of the shoe, will automatically act as a portable mobile charger.
Named ‘Walkie Mobi Charger’, this gadget generates electricity up to six volts, as against five volts released through a plug point and ensures that the phone battery is charged at a faster pace. So if a plug-in charger takes half-an-hour to charge a phones up to 25%, the walking device will charge 40% of the battery in the same time.
“We have made this prototype as an attachment that can fit below a sports shoe. With more funds and better technical support, we plan to make this an inbuilt feature inside the sole of the shoe,” said Gangadharan.
This innovative design took over three months to materialise. The mould, wiring and shaping the metal sheets were all made by the two school boys. “Before the final model took shape, we had made three other models. In the first model, we had planned it to be like a proper shoe which would be attached to the belt but that seemed too bulky. We finally made something that would be convenient,” said Bhalla.
The device functions on the principle of electromagnetic induction. The compression and relaxation caused by walking creates pressure on the sponge attached in the middle which produces electricity.Two LEDs, blue and red, indicate the supply of electricity and battery charging, respectively.
The device is equipped to charge several models of phones. All one needs to do is connect the charger to the shoe while the phone rests in your pocket. “This is an effective way to utilise an alternate source of energy and is also a healthy way to decrease your electricity bills,” they said.
