Design and analysis of a broadband vibratory energy harvester using bi-stable piezoelectric composite laminate

Strongly coupled piezoelectric energy harvesters: Finite element modelling and experimental validation

“…For energy harvester design and optimisation, commercial software packages such as ANSYS and COMSOL provides a powerful tool because of their ability to simulate complicated transducer structures [23,24] and more importantly to couple the fields of mechanical structures, piezoelectricity and electrical circuits. This enables the development of piezoelectric-circuit coupled finite element models (FEMs), in which piezoelectric energy harvesters are connected to electrical circuits.…”

Nonlinear Characterization of a Bistable Energy Harvester Dynamical System

“…2, may present better power recovering performances, when compared to the linear counterparts. The richness of such devices dynamics, combined with the new available improvements in numerical simulation tools and computing resources, have been propelling a wide variety of analysis considering different devices layouts, as seen in [10,18,34,39] for composite and cantilever vibrating beams, or in [11,15,25,26] for inverse pendulum layouts and new designs as those discussed in [5,8,16,33,45].…”

Design Scalability Study of the Γ-Shaped Piezoelectric Harvester Based on Generalized Classical Ritz Method and Optimization

“…An additional optimization study at M allowed = 37.5 g found the power output 1.857 mW (the optimized design variables can be found in Table 4) and confirms this linear relation-only 0.6% different from a predicted value (1.845 mW). Table 5 [61][62][63][64][65][66][67] shows the NPDs and modified NPDs of various PE harvesters and their specification in terms of piezoelectric material, excitation amplitude, piezoelectric material volume, system volume, power output, and total mass. The modified NPD is a new index defined similarly as the NPD.…”
