“…Recently, several natural materials were found with ability to harvest electric energy from dynamics of mechanical power sources ensuring low-cost production, as well as ecological safety and biocompatibility during uninterrupted or intermittent contacts with the human body. Humans may provide a large amount of mechanical energy during their daily living (the electric power may exceed 70 W), which can be converted to produce significant amounts of useful energy by triboelectric generation [40,41]. Many applications (e.g., innovative biomedical sensors that monitor daily activity and functioning of the organism and multifunctional medical devices) require biocompatible materials in contact with human skin or implanted inside the body [42][43][44].…”

“…For this reason, these equations are transformed from the modal coordinate into direct calculation of the relative movement of The system of Equations ( 37) and (38) is still not suitable for prediction of harvested power due to using the modal coordinate. For this reason, these equations are transformed from the modal coordinate into direct calculation of the relative movement of the bimorph's free end q defined by (32) as…”

“…For this comparison, typical mechanical vibrations of a human forearm which are encountered in wearables applications were measured [32] and analyzed using the developed model. The measured time-course of acceleration a(t), see Figure 11a, is generated by a random movement of the forearm and can be thought of as a representative of random vibrations as can be seen from its spectrogram in Figure 11b.…”

This paper deals with analytical modelling of piezoelectric energy harvesting systems for generating useful electricity from ambient vibrations and comparing the usefulness of materials commonly used in designing such harvesters for energy harvesting applications. The kinetic energy harvesters have the potential to be used as an autonomous source of energy for wireless applications. Here in this paper, the considered energy harvesting device is designed as a piezoelectric cantilever beam with different piezoelectric materials in both bimorph and unimorph configurations. For both these configurations a single degree-of-freedom model of a kinematically excited cantilever with a full and partial electrode length respecting the dimensions of added tip mass is derived. The analytical model is based on Euler-Bernoulli beam theory and its output is successfully verified with available experimental results of piezoelectric energy harvesters in three different configurations. The electrical output of the derived model for the three different materials (PZT-5A, PZZN-PLZT and PVDF) and design configurations is in accordance with lab measurements which are presented in the paper. Therefore, this model can be used for predicting the amount of harvested power in a particular vibratory environment. Finally, the derived analytical model was used to compare the energy harvesting effectiveness of the three considered materials for both simple harmonic excitation and random vibrations of the corresponding harvesters. The comparison revealed that both PZT-5A and PZZN-PLZT are an excellent choice for energy harvesting purposes thanks to high electrical power output, whereas PVDF should be used only for sensing applications due to low harvested electrical power output.

“…In the last 10 years or so, several studies on bistable and/or multistable piezoelectric cantilever beams with auxiliary magnets have thus been performed [ 80 , 81 , 82 , 83 , 84 ]. Although a wider frequency spectrum is indeed attained, potentially leading to higher power outputs, there is a conspicuous increase in the analytical complexity of the resulting strongly chaotic oscillations with large amplitudes, as well as a substantial increase of the volume of the resulting devices [ 85 , 86 , 87 ].…”

With the aim of increasing the efficiency of maintenance and fuel usage in airplanes, structural health monitoring (SHM) of critical composite structures is increasingly expected and required. The optimized usage of this concept is subject of intensive work in the framework of the EU COST Action CA18203 “Optimising Design for Inspection” (ODIN). In this context, a thorough review of a broad range of energy harvesting (EH) technologies to be potentially used as power sources for the acoustic emission and guided wave propagation sensors of the considered SHM systems, as well as for the respective data elaboration and wireless communication modules, is provided in this work. EH devices based on the usage of kinetic energy, thermal gradients, solar radiation, airflow, and other viable energy sources, proposed so far in the literature, are thus described with a critical review of the respective specific power levels, of their potential placement on airplanes, as well as the consequently necessary power management architectures. The guidelines provided for the selection of the most appropriate EH and power management technologies create the preconditions to develop a new class of autonomous sensor nodes for the in-process, non-destructive SHM of airplane components.
