Harvesting Energy stands alone as one of the most promising techniques for approaching the global energy problems without depleting natural resources. Energy can be obtained while walking on certain arrangements like footpaths, stairs, platforms and these systems can be install in the dense populated areas. Piezo materials and Cam-Gear arrangement is used to harvest energy from footsteps of human beings. Piezoelectric crystal senses the vibrations and electrical signals are produced due to

... mation of the crystal. In Cam-Gear arrangement footsteps which is linear motion is converted into rotary motion. This rotary motion is fed to stepper motor which converts mechanical energy into electrical energy, which is stored in a battery. The stored energy can be used for lighting.
