a) Schematic showing the various energy sources from which piezoelectric power is generated, the different piezoelectric materials, PENGs and their fabrication techniques and the various applications in the center. b) The plot of piezoelectric coefficients (d33) of various materials. The arrow points toward future outlook suggesting that a material with higher d33 than 600 pC N–1 needs to be developed to meet the piezoelectric requirements of the future.
