Science-Accepted 8 Piezoelectric V EM Induction
• -->>continued: FREE ENERGY TYPES; Micro Current Energy Harvesters:
2 Piezoelectricity: OTHER PIEZO, PIEZO LIKE MECHANICS or combo:
• iii -Radio Frequency harvesting by piezo system with cantilever
system(Mahmoud Al Ahmad+), iv-In a way the same thing but what is fully
categorized Acoustic Metamaterial can maximize piezo electricity production by
impedance matching surface, or coiling up structure of labyrinthine units
(Shuibao Qi+), or membrane types(Junfei Li+), & can range 15-20%+
efficiency(Guancong Ma+), while also can function as effective sound
absorber/insulator simultaneously.
• v-Far more minute level vibration sensitive Nanostructure or
NanoWire/NEMS(NanoElectroMechanical Systems) can be much more efficient
than conventional piezoelectric (KAIST: Keon Jae Lee+),
• vi-Other mechanical combination are explored and deemed to have advantages:
Shape Memory Alloy(SMA, by temperature change)(p73,74), Magnetic Shape
Memory Alloy(MSMA)(AdaptaMat Oy: MSMA without piezo combo),
vii-Coupling of Helmholz cavities in addition to regular cantilever beams to
amplify resonance(frequency matching)(D Ezhilarasi+), Or with duel
cantilever(Ping Li+), Or paired cavities to further augment an order of
magnitude larger energy harvest and 4times higher voltage(Xiao Peng+) than
already increased power by a cavity itself. 15
