In the present era as there is a decrease in energy consumption of portable electronic devices, the hypothesis of harvesting renewable energy in our surroundings provoke a renewed interest. The need for energy is also increasing at a fast rate, which has exhausted lots of resources. So, there is a need to produce more energy. Mechanical energy harvesting happens to be the most prominent energy harvesting technique. This utilizes piezoelectric components where electric charge is generated by deformations produced. This technical paper emphasis on one such method through piezoelectric material. The motive is to obtain pollution–free energy source and to utilize the energy being wasted. A piezoelectric substance is one that produces an electric charge when a mechanical stress is applied. Piezoelectric materials can be used as a mechanism to transfer mechanical energy, usually ambient vibration, into electrical energy that can be stored and used to power other devices. Conversely, a mechanical deformation is produced when an electric field is applied. Piezo-film can generate enough electrical density that can be stored in a rechargeable battery for later use. Currently, there is a need to utilize other forms of energy at passenger terminals like airports and railways across the world. Cleaner, more useful forms of electrical power are needed in order to keep costs lower and to ensure a pollution free environment for future generations. The use of piezoelectric devices installed in the terminals will capture the kinetic energy from foot traffic. Such a source of power can then be used to operate lighting systems. In this paper, the concept of piezoelectricity and piezoelectric effect is well discussed. The various applications based on piezoelectric effect are also elaborated. Future prospects regarding piezoelectric materials in day-to-day life are also well highlighted.
