Piezoelectric energy harvesters (PEHs) have the potential to power low‐power electronic devices and can advance, self‐powered, autonomous electronics to the next level. Conventional ceramic‐based piezoelectrics have various properties such as fragility, rigidity, toxicity, high density, and lack of design flexibility which limit their use in more flexible environments. A ton of research has been carried out and published on novel piezomaterials, their transduction mechanisms, analytical models, and electrical circuits to improve various aspects of PEHs. Among these materials, studies on polymeric cellular (or foamed) ferroelectrets or piezoelectrets as PEHs have grown significantly since their discovery. Also, very limited or short reviews are available covering only few aspects. There is a necessity of recognizing their past and present advances in their various generation technology and polymer systems. Herein, a broader review of almost all conventional and recent polymeric foam‐based piezoelectrics for PEH applications is summarized. These cellular polymer piezoelectric systems either in bulk, composite, layered, or film form can be fabricated, and depending on the application and conditions, different polymers groups, mainly, polyolefins, polyester, fluoropolymer, and others, are considered. Their applications and future perspectives are also presented and discussed.

“…[103][104][105][106][107][108] The 33-mode PEHs have been used in various applications, such as in the roadway to collect mechanical energy from vehicles and in shoes to harvest mechanical energy from human motion. [109][110][111][112][113][114][115][116] To fabricate the 33-mode PEHs operating at resonance frequency, seven Pb(Zr,Ti)O 3and (Na,K)NbO 3 -based piezoelectric ceramics were used and FOM on for the piezoelectric ceramics of these 33-mode PEHs has been investigated. [117] Particularly, ring-type piezoelectric ceramics were used to fabricate the 33-mode PEHs (Figure 16a) because they can be mounted on a specimen holder at the same position, as shown in Figure 16b, resulting in reliable electrical output power.…”

Piezoelectric Energy Harvesting Design Principles for Materials and Structures: Material Figure‐of‐Merit and Self‐Resonance Tuning

Piezoelectric energy harvesters (PEHs) aim to generate sufficient power to operate targeting device from the limited ambient energy. PEH includes mechanical-to-mechanical, mechanical-to-electrical, and electrical-to-electrical energy conversions, which are related to PEH structures, materials, and circuits, respectively; these should be efficient for increasing the total power. This critical review focuses on PEH structures and materials associated with the two major energy conversions to improve PEH performance. First, the resonance tuning mechanisms for PEH structures maintaining continuous resonance, regardless of a change in the vibration frequency, are presented. Based on the manual tuning technique, the electrically-and mechanicallydriven self-resonance tuning (SRT) techniques are introduced in detail. The representative SRT harvesters are summarized in terms of tunability, power consumption, and net power. Second, the figure-of-merits of the piezoelectric materials for output power are summarized based on the operating conditions, and optimal piezoelectric materials are suggested. Piezoelectric materials with large k ij , d ij , and g ij values are suitable for most PEHs, whereas those with large k ij and Q m values should be used for on-resonance conditions, wherein the mechanical energy is directly supplied to the piezoelectric material. This comprehensive review provides insights for designing efficient structures and selection of proper piezoelectric materials for PEHs.

“…These models have been proved useful for the calculation of anisotropy of metal sheets, as for instance in the work of Sidor et al [22] which shows that the most accurate predictions of r values for aluminum sheets subjected to asymmetric rolling are obtained using the ALAMEL model, [22] although only marginally better than using models based on the Taylor theory (or VPSC). Other models that have been tried in this context include the VPSC model, [22,31] a combination of Taylor with ALAMEL used by Gawad et al [32,33] or the N-site interaction model by Delannay, Kalidindi and Van Houtte. [34] Even full-field solutions using crystal plasticity finite element modeling (CPFEM) have been applied to the problem by the group of Raabe and Roters in the Max-Planck Institut fu¨r Eisenforschung [35] and also using crystal plasticity fast Fourier transforms (CPFFT) to solve crystal plasticity problems in the frequency domain.…”

Plastic deformation of metallic materials is an inherently anisotropic process as a result of the presence of preferential orientations in their crystallographic texture. Crystal plasticity modeling, which allows simulating the response of polycrystal aggregates taking into account their texture and other microstructural parameters, has been extensively used to predict this behavior. In this work, crystal plasticity models are used to deal with the opposite problem: given a desired behavior, determine how to modify a texture to approximate this behavior in the most efficient way. This goal can be expressed as an optimization problem, in which the objective is to find the texture with the best formability properties among all the possible ones. An incremental optimization method, based on the gradient descent algorithm, has been developed and applied to different initial textures corresponding to typical steel and aluminum sheet products. According to expectations, the textures found present a stronger c fiber component. Moreover, the method sets the basis for the development of more complicated optimization schemes directed toward optimizing specific materials and forming processes.
