INTRODUCTION

Did you know that you can produce electricity by just walking? Here's a little

science experiment that will show you a little secret on making insoles that can

charge USB devices! The challenge is to make a slip-on insole that can produce

enough electricity to charge batteries/ USB devices.

Concept Behind The Project

Piezoelectricity was present ever since mid-

18th century. Piezoelectricity

is the electric charge that

accumulates in certain solid

materials (such as crystals,

certain ceramics in response

to applied mechanical stress.

This sounds familiar! Yes they

do, you can actually find those

piezo elements in your old/

outdated earphones from the

90's.

SCOPE

As funny as it sounds, charging a phone with your shoe isn't

really joke. Who knows maybe someday shoe companies like Nike could use these

insole generators to power fitness chips (inside shoes) that would sync to your

phone wirelessly. This way, you don't have to charge your smart-shoes just to sync

them with your phone.

MATERIALS

Generic USB Power bank

Piezoelectric Transducers (6x)

1N4007 Rectifier Diodes (4x)

Connecting Wire (at least 12")

Pair Of Shoes

Contact Adhesive

Digital Multimetre

PiezoelectricTransducers

• Rated Maximum Voltage (Vp-p Square Wave) : 30 Vp-p

• Capacitance : 20,000 pF ±30%

• Resonant Frequency : 4,200 ±500 Hz

• Resonant Impedance : 300

• Operating Temperature : -20 to +60°C

• Storage Temperature : -20 to +70°C

CIRCUITS

Estimated = 700

PROGRESSmade in our project is

We have bought all the required material for the project.

We have enclosed the bill of the material which we had bought.

We have also enclosed the photo copy of the material as a proof of concept.

We have also built a diode rectifier to convert the DC to AC output.

We have also modified the Shoe , to insert the required circuit setup in the insole of the shoe.

We have also enclosed the picture of the insole of the shoe ,to which the circuit Is going to be inserted.

CONCLUSION

As funny as it sounds, producing electricity through a footwear isn't really joke.

Who knows maybe someday shoe companies like Nike could use these insole

generators to power fitness chips (inside shoes) that would sync to your phone

Hence in the end of the project we would able to generate electricity through a

foot wear.
