FABRICATION AND CHARACTERIZATION OF FLEXIBLE PIEZOELECTRIC GENERATOR COMPOSED OF POTASSIUM SODIUM NIOBATE ( KNN ) BASED CERAMICS DOPED WITH LITHIUM /PVDF FOR ENERGY HARVESTING APPLICATIONS

Abstract

Energy Harvesting has received a lot of attention recently for powering low voltage electrical appliances. We must create and use efficient, clean and renewable energy sources if we are to meet growing global energy users and needs. Researchers are working on replacing batteries in this area and piezoelectricity has been suggested as a promising source. Piezoelectric materials have been widely used to generate electricity. Using piezoelectric materials, this article seeks to create a new form of energy. This essay focuses on piezoelectric devices as a potential energy source, investigates multi-device connections and seeks to generate as much power as possible. Piezoelectric materials can transform mechanical stress into displacement in a dielectric medium and vice versa, making them suitable for use as sensors, actuators and transducers. Due to their high stress response and adaptability, lead-based materials have attracted the most attention; but lead toxicity mandates government regulations restricting their use. Although KNN supported materials appear to be a promising alternative to hazardous Pb based piezoelectric, the distinction between thin films and bulk materials has not been fully evaluated. KNN based materials exhibit qualities that make them ideal for actuator applications, prompting the search for suitable alternative materials. Results will highlight the beneficial practical consequences of the use of piezo systems, providing a clearer picture of the difficulties and benefits of using piezoelectric materials as a support for power generation. We have only stolen so much from natural as people. The fading line of ecological equilibrium needs to be restored, renewed and darkened. Only more recent green energy ventures can make this viable. Studying earlier writings and research on this technology would significantly strengthen the philosophy. The energy generated can be valuable, according to the findings of numerous study studies. The work approaches the above assumptions and looks for maximum power extraction from piezo device.
