Abstract

The global free energy crisis and environmental pollutions caused mainly by the increased consumption of nonrenewable free energy sources prompted researchers to explore alternative energy technologies that tin harvest energies bachelor in the ambient environs. Mechanical energy is the nearly ubiquitous ambient energy that can be captured and converted into useful electric power. Piezoelectric transduction is the prominent mechanical energy harvesting mechanism owing to its high electromechanical coupling cistron and piezoelectric coefficient compared to electrostatic, electromagnetic, and triboelectric transductions. Thus, piezoelectric energy harvesting has received the utmost interest past the scientific community. Advancements of micro and nanoscale materials and manufacturing processes accept enabled the fabrication of piezoelectric generators with favorable features such as enhanced electromechanical coupling factor, piezoelectric coefficient, flexibility, stretch-power, and integrate-ability for diverse applications. Besides that, miniature devices with lesser power need are realized in the market with technological developments in the electronics manufacture. Thus, it is anticipated that in near future, many electronics will be powered by piezoelectric generators. This paper presents a comprehensive review on the state-of-the-fine art of piezoelectric energy harvesting. The piezoelectric energy conversion principles are delineated, and the working mechanisms and operational modes of piezoelectric generators are elucidated. Recent researches on the developments of inorganic, organic, composite, and bio-inspired natural piezoelectric materials are reviewed. The applications of piezoelectric energy harvesting at nano, micro, and mesoscale in various fields including transportation, structures, aerial applications, in water applications, smart systems, microfluidics, biomedicals, wearable and implantable electronics, and tissue regeneration are reviewed. The advancements, limitations, and potential improvements of the materials and applications of the piezoelectric free energy harvesting technology are discussed. Briefly, this review presents the broad spectrum of piezoelectric materials for make clean ability supply to wireless electronics in diverse fields.
