energy produced by it would increase too. When a person steps on such tiles piezoelectric crystal under the tiles would experience some mechanical stress which makes electric charge to built up on crystal’s surface which can be collected by use of electrodes. This kind of energy can be stored in capacitors and power can be transfer to energy deficient regions. Japan has already started experimenting use of piezoelectric effect for energy generation by installing special flooring tiles at its capitals’ two busiest stations. Tiles are installed in front of ticket turnstiles. Thus every time a passenger steps on mats, they trigger a small vibration that can be stored as energy [5]. Fig 2.

The piezoelectric effect exists in two properties first the piezoelectric effect is a reversible process in that materials exhibiting the direct piezoelectric effect (the internal generation of electrical charge resulting from an applied mechanical force) second it also exhibit the reverse piezoelectric effect (the internal generation of a mechanical strain resulting from an applied electrical field) this is the best way of power harvesting [4].

[7].These floors are using the piezoelectric effect. As the floor is compressed by the dancers feet the piezoelectric material makes contact and generate the electricity around 2-20 watts. It depends on the impact of the feet. The constant compression of piezoelectric crystals causes a huge amount of energy to be generated, which can comfortably drive the remotely placed low power consuming devices [8]. 3.4.

Fig 5. Piezoelectric crystals installed in shoe Apart from tiles, roads, dance floors, attempts are made to harvest energy from our daily movements by installing piezoelectric crystals in the shoes also. These shoes would have piezoelectric crystals at the rear end or near heel. Thus with each step piezoelectric crystal would go through pressure and force which in turn can generate enough energy to power cell phones, mp3 players etc. If these such shoes undergo through movements daily then these will be able to generate electricity enough to charge up the small electronic devices or gadgets. Often we can do that with a piezoelectric transducer, a transducer is simply a device that converts small amount of energy from one kind to another for instance converting light, sound or mechanical pressure into electrical signals[9].
