Magneto-Mechano-Electric (MME) Energy Harvesting Properties of Piezoelectric Macro-fiber Composite/Ni Magnetoelectric Generator

Abstract

Asymmetric and symmetric magnetoelectric (ME) laminates structures of piezoelectric macro-fiber composite (MFC)/nickel (Ni) were fabricated and investigated their ME and magneto-mechano-electric (MME) energy harvesting responses to an applied magnetic/ mechanical stimulations. Both the structures strongly revealed the dependence of ME voltage coefficient (α ME ) on applied magnetic field directions with an important feature of a zero-bias field ME response. This is much more beneficial for designing the magnetic field sensors. The fabricated MFC/Ni structures exhibited good energy harvesting response to applied simultaneous magnetic/ mechanical vibrations of lab magnetic stirrer. The electric power was successfully harnessed from magnetomechanical stimulations; the resulting potential and power were up to ,20 V p-p and ,6 μW respectively, which are quite enough power to light a commercial red LED with traditional rectifier circuit and capacitor. Hence, the present MFC/Ni ME generators provide their future feasibility having self-biasing feature for designing the magnetic field sensors as well as for powering small consumer electronic devices and wireless sensor network systems by exploiting mechanical/magnetic stimulations from surrounding.

Magneto-Mechano-Electric (MME) Composite Devices for Energy Harvesting and Magnetic Field Sensing Applications

“…Piezoelectric single crystal and magnetostrictive Ni layer embedded MME generators display electrical output power on the order of a hundred μW under a weak magnetic field [ 6 , 8 , 40 , 41 ]. The performance of MME generators is enhanced due to the high anisotropic piezoelectric response (d 32 mode) of SFC.…”

High performance of polycrystalline piezoelectric ceramic-based magneto-mechano-electric energy generators

“…In recent years, the Magneto-Mechano-Electric (MME) energy generator has shown excellent potential for low amplitude magnetic field to electrical energy conversion. [12][13][14][15][16][17] The typical MME generator is a cantilever structure comprising a magnetoelectric (ME) composite structure of piezoelectric and magnetostrictive layers and permanent magnets as proof mass [11,12]. The basic factors contributing to the output electrical performance are magnetoelectric (ME) effect, magnetic flexural torque from the magnetic proof mass and their synergetic interaction under externally applied magnetic field [15].…”

Direct and converse nonlinear magnetoelectric coupling in multiferroic composites with ferromagnetic and ferroelectric phases

“…To fully explore this characteristic, ferromagnetic and ferroelectric materials with strong nonlinear hysteretic characteristics under an applied magnetic and electric field, respectively, are frequently investigated [20][21][22][23][24][25]. Many experiments have shown that such nonlinearity could lead to stronger nonlinear ME coupling [26][27][28][29][30][31]. Such combination makes the multiferroic composites to have very complex nonlinear hysteretic characteristics, and, when properly tuned, there are many novel applications that the multiferroic composites could render.…”

“…To provide some insights into the dimensional effects, Burdin et al [30] obtained the ME effect hysteresis in Ni-PZT structure. Kambale et al [31] fabricated the asymmetric and symmetric laminated ME structures composed of piezoelectric macro-fibre and Ni, and then measured the ME coefficients along the length, width and thickness directions of the laminated structures.…”
