“…In lower frequency zone, value of dielectric constant is on higher side due to effect of various types of polarization mechanisms. However, as the frequency increases further, its value goes on reducing due to inability of electric dipoles to get aligned due to rapidly changing electric field 55 . The values of dielectric loss also increased on BMP addition as presented in Figure 9b.…”

An increasing trend in creating materials with a greater extent of sustainability from an ecological and financial perspective involves usage of bio resources and industrial residues. In this paper, leftover bamboo micro particles (BMP) from bamboo factories were collected and used as fillers with polyvinylidene fluoride (PVDF) matrix in varying concentrations (1, 3, 5, 7, and 9 wt.%) to fabricate low-cost composite films using solvent casting route for mechanical energy harvesting purpose. Out of the prepared samples, PVDF with 5 wt.% BMP showed maximum electroactive phase content (82%), tensile strength (34.23 MPa), and piezoelectric voltage (6.5 V) among the untreated samples. PVDF with 5 wt.% BMP is then subjected to NaOH treatment for further enhancement in overall performance. PVDF with 5 wt.% treated BMP also showed 467% increment in output voltage and 235% increment in output current as compared to pure PVDF. The piezoelectric output voltage of PVDF with 5 wt.% treated BMP is then measured under impact loading conditions to determine its suitability as an impact sensor. A bamboo-based piezoelectric impact sensor that is highly sensitive and cost-effective opens enormous possibilities for sustainability and circular economies.

“…Most recently, the piezoelectric, ferroelectric, and ferromagnetic properties of BiFeO 3 ‐based solid solutions have been greatly improved, by using the cation modifications 8‐18 and forming the ternary system 19‐25 . Table 1 summarizes the piezoelectric, ferroelectric, and ferromagnetic properties of BiFeO 3 ‐based solid solutions.…”

Dense 0.6(Bi0.9La0.1)(Ga0.05Fe0.95)O3‐0.4(Pb1‐xBax)TiO3 (BLGF‐PBT, x = 0, 0.1, 0.2, 0.3, and 0.4) ceramics with different Ba contents were prepared by the solid‐state reaction method, and effects of Ba contents on the structure and multiferroic properties were investigated. X‐ray diffraction results indicate that the Ba‐modified BLGF‐PBT ceramics exhibit single perovskite structure without detectable secondary phases, and a transition from tetragonal phase to rhombohedral one takes place with the increase of Ba content. The piezoelectric constant d33, remanent polarization Pr, and remanent magnetization Mr are improved by the Ba substitution simultaneously. Values of Pr, Mr, and d33 of BLGF‐PBT ceramics for the composition of x = 0.3 with the coexistence of tetragonal and rhombohedral phases are 20 μC/cm2, 0.05 emu/g, and 256 pC/N, respectively, much higher than those without Ba modification. The significantly improved d33 and Mr indicate that BLGF‐PBT ceramics with Ba modification provide alternative materials for multifunctional devices.
