Polymeric piezoelectric composites for energy harvesting applications are considered a significant research field which provides the convenience of mechanical flexibility, suitable voltage with sufficient power output, lower manufacturing cost, and rapid processing compared to ceramic‐based composites. This review focuses majorly on the basic theory and principles behind piezoelectric energy harvesting (PEH) devices, followed by specified materials used for the different devices. Different structural configurations associated with fabrication of PEH devices are discussed in detail along with their major advantages and drawbacks. Numerous classes of piezoelectric polymers such as polyvinylidene fluoride, polylactic acid, cellulose, polyamides, polyurea, polyurethanes, and their composites used for energy harvesting applications as a productive alternative of lead‐based piezo‐ceramics, are extensively addressed and explored. Additionally, current global and Indian scenarios associated with PEH devices, major challenges associated with them, and the future perspective of such devices are also reported in this review.

“…The increasing attention on the polymer composite over the past few decades is due to widespread applications for the development of functional materials to fulfill the requirements of cheap, reliable, durable and environmentallyfriendly batteries which are necessary for the most efficient energy storage and conversion device applications [1][2][3][4][5]. Polymer matrices with embedded inorganic fillers, nanoparticles or clusters are particularly important for optical, electronic, dielectric and magnetic applications.…”

Frequency dependent dielectric, modulus, impedance and AC conductivity study of Poly Vinyl Alcohol with 25 vol.% of Yttrium modified Barium Zirconium Titanate ceramic have been investigated. The single phase Yttrium modified Barium Zirconium Titanate ceramics have been synthesized by conventional solid state route. The relaxation mechanism of dielectric and modulus study is due to the segmental motion of polymer chain along with the dipole orientation of ceramic in the polymer composite. The Nyquist plot of impedance shows two semicircles, which represents the bulk and interfacial effect of polymer composites. The activation energy decreases with incorporation of higher Yttrium modified Barium Zirconium Titanate ceramics in the polymer matrix due to the even distribution of ceramic in the polymer composite. The different activation energy obtained from conduction and relaxation of the composite indicates that various mechanisms are involved in the conduction and relaxation process.

“…The inclusion of ceramic grains in the polymer matrix enhanced the dielectric permittivity from 5 (for polyurethane) to 24. The activation energy of the composite is also comparable to that of polyurethane [5].…”

The present study gains importance through investigation of the damage analysis considering that most of the impact parameters have been undertaken experimentally. This work is focused on a qualitative and quantitative study of the low-velocity impact response of four different types of specimens with glass fabric reinforced plastics. The laminate specimens were fabricated according to the manufacturers' recommendations. The specimens were impacted experimentally using an instrumented impact tester with a hemispherical tip.
