“…Recently, there has been rapid proliferation of the demand for the energy harvesting technology latest devices. This technology has advanced significantly and is being adopted on a larger scale since the discovery of piezoelectric polymers in the last two decades as transducers/harvesters and as one of the main building blocks of an energy harvesting system [1][2][3]. Notably, energy harvesting technology using piezoelectric materials is one such method which exploits mechanical energy from various sources when subjected to kinetic energy such as vibrations, movements, and sounds from heat waves or motor bearing noise from aircraft wings and other sources, to convert that energy into an electric current or voltage to help mitigate energy depletion all around the globe [4][5][6][7].…”

“…The relations (1), derived from the differentiation of the internal energy of a piezoelectric crystal, require the definition of the tensors s E ij , e in and ε T nm , while the other mechanical, electric, and piezoelectric tensors can be consequently derived by using the relations contained in Table 2. For single-term characterization, the relations contained in [28,29] have been employed.…”

“…Energy harvesting based on piezoelectric technology has been developed over the last decades for charging portable electronic devices and/or for micro-sensors and actuators, where the prominent aspect is to ensure the operation of the electronic devices [1,2]. Indeed, a literature survey on piezoelectric energy harvesters shows that they are classified into three groups with reference to their correspondent sizes: macro-and mesoscale, MEMS (Micro Electro-Mechanical Systems) scale, and nanoscale [3].…”

The present paper deals with the promising energy harvesting applications of a composite piezoelectric metal support that is properly designed for the rotor of a mechanical system. The aim is to determine whether the vibrational power coming from the static residual imbalance, which is generally considered to be an undesired and useless side-effect of the rotation, can be converted into electric power and then stored to be used in other applications. The analysis, starting from the Jeffcott rotor model and the piezoelectric constitutive equations, has been carried out by developing an approximated linear model of a piezoelectric support, in order to theoretically evaluate the performance and the feasibility of the proposed system. The accuracy of the exploited analytical model has been validated for both static and dynamic operations by 3D Ansys® Mechanical APDL. Finally, a MatLab®/Simulink® model has been built to simulate the electric behavior of the piezoelectric material, and to estimate the power that it is possible to extract via an alternative/direct current converter (AC/DC converter). The numerical results achieved confirm the effectiveness of the proposed energy-harvesting system.

Recent advancements in wearable technology have improved lifestyle and medical practices, enabling personalized care ranging from fitness tracking, to real-time health monitoring, to predictive sensing. Wearable devices serve as an interface between humans and technology; however, this integration is far from seamless. These devices face various limitations such as size, biocompatibility, and battery constraints wherein batteries are bulky, are expensive, and require regular replacement. On-body energy harvesting presents a promising alternative to battery power by utilizing the human body's continuous generation of energy. This review paper begins with an investigation of contemporary energy harvesting methods, with a deep focus on piezoelectricity. We then highlight the materials, configurations, and structures of such methods for self-powered devices. Here, we propose a novel combination of thin-film composites, kirigami patterns, and auxetic structures to lay the groundwork for an integrated piezoelectric system to monitor and sense. This approach has the potential to maximize energy output by amplifying the piezoelectric effect and manipulating the strain distribution. As a departure from bulky, rigid device design, we explore compositions and microfabrication processes for conformable energy harvesters. We conclude by discussing the limitations of these harvesters and future directions that expand upon current applications for wearable technology. Further exploration of materials, configurations, and structures introduce interdisciplinary applications for such integrated systems. Considering these factors can revolutionize the production and consumption of energy as wearable technology becomes increasingly prevalent in everyday life.
