The piezoelectric material is a type of advanced material that produces an electric current when it is under mechanical stress(direct piezoelectric effect). It is a reversible process because when an electric current is applied, its shape also gets changed(inverse piezoelectric effect). There are a variety of  piezoelectric materials that shows these phenomena e.g Poly lead Zirconate Titanate(PZT), Polymer thick film(PTF)

Piezoelectric materials


Why piezoelectric material is important?

Its importance is hidden in its property of producing an electric current while under mechanical stress. By using this phenomenon, we can do energy conservation. Imagine road’s light is charged due to your car on a road. The laptop will be charged while you are typing. So, this advanced material will bring a lot of advanced changes in human life.

The drawback of piezoelectric materials 

  •  Most piezoelectric materials contain lead as the main element, which is a cause of environmental pollution. 

  • A small quantity of current is produced by the piezoelectric material.

  • Difficult to work with these types of materials.

Applications 

The major use of piezoelectric material in different fields of life are as follow 

  • Optics, measuring technology 

  • Medicine, life science

  • Microelectronics 

  • Mechanical engineering



Conclusion 

Piezoelectric materials are one of the most important features of Nanotechnology. It is a smart material that can reduce our energy consumption. It is a great source of energy conservation in the future. So far, there is more research is needed in this field. So, the piezoelectric material could fulfill the human demand on a larger scale. It is the future of energy.
