POWER GENERATION USING PIEZOELECTRIC MATERIALS


POWER GENERATION USING PIEZOELECTRIC MATERIALS
Introduction –

What are Piezoelectric Materials?
         Piezoelectric materials are those materials which on applying pressure undergo changes in its dimension and produce electricity which is known as PIEZOELECTRICITY.

  For example LEAD ZICRONATE TITANATE will generate measurable amount of piezoelectricity when it is deformed by about 0.1% of its original dimensions.
  
    As u can see the above picture, when we compress the material, deflection can be seen in the voltmeter which indicates there is some potential difference in material.

Applications -

   Piezoelectric materials are used in day to day life such as the house hold gas stove lighter which ccontains               piezoelectric materials which on pressing produces spark and lights the gas stove, but now a days electric lighters are used but yet it was a great invention. Other applications are cigarette lighter, detonators, sensors etc.





A SIMPLE MECHANISM OF PIEZOELECTRICITY SHOWN ABOVE


FUTURE APPLICATIONS –

My idea was to generate considerable amount of electricity by using such kind of materials.
We can generate electricity by using these materials in staircases by replacing them with the tiles, marbles which we use today or wherever it is economical to install. The concept is simple with increase in surface area the power generation will also increase, so we need more area and large amount of pressure which can be fulfilled by public places like railway stations foot over bridges, platforms etc.
