In view of providing consistent power to remotely situated microelectronic devices, this paper proposes a full‐length cavity‐based novel segmented doubly clamped piezoelectric energy harvester (DCPEH). The paper starts with the analysis of different possible configurations of segmented DCPEH beam corresponding to single, double, and triple cavity systems involvement. It has been observed that for full‐length single cavity involvement, the segmented DCPEH beam is resonate at minimum value (70 Hz) of resonance frequency. However, the observed value of output power response (76 mW) at such low resonant frequency is not so appropriate. Therefore, the performance of full‐length cavity‐based segmented DCPEH beam has been further investigated for series and parallel composite structural design of PMN‐35%PT (M1) and PZT‐5H (M2) piezoelectric materials. The improved value of output power (313 mW) response at low (68.8 Hz) resonant frequency has been achieved with M2‐M1 series composite form of piezoelectric materials.

“…Therefore, the total radial stress acting on the disk is obtained as T = 2 T 1 . As the piezoelectric PVDF disk is polarized in the 3‐direction, the piezoelectric constitutive equation is written as [ 29,30 ]

D_{3} = d_{31} T + ε_{33}^{T} E_{3}

where E 3 is the electric field and D 3 is the electric displacement along the 3‐direction; T is the mechanical stress along the radial direction; d 31 is the piezoelectric strain constant; and ε 33 T is the dielectric permittivity. Substituting the short‐circuit condition E 3 = 0 in Equation () yields: D 3 = d 31 T = 2 d 31 T 1 .…”

The last two decades have witnessed an ever‐increasing research effort devoted to the development and application of magnetoelectric (ME) sensing composites. Herein, the ME effect in a metallic/polymeric composite fabricated by adhering silver electrodes to two surfaces of one poly(vinylidine fluoride) (PVDF) disk is explored. To obtain obvious ME response, the resonance frequency of the experimental setup is measured. Furthermore, it is proved that the ME coupling in the composite (silver/PVDF/silver) originates from the product effect of the piezoelectric effect and ampere force produced by eddy currents under DC bias magnetic fields. By observing measurement results, the ME voltage is approximately considered to be proportional to both AC and DC magnetic fields. Consequently, the average ME voltage coefficient is obtained as 384.73 mV cm−1 Oe at a DC magnetic field value of 1000 Oe. Considering the magnetic fields and eddy current, a theoretical model of ME coupling is developed by combining the ampere force expression and piezoelectric equations, which matches well with measurement results. Without the need of magnetic phase and an external power supply, the proposed disk with excellent linear responses and a considerable ME voltage coefficient has the potential for application in real‐time monitoring sensors.
