“…Apart from the tuning of the material composition, the rest of the piezoelectric energy harvesting research has focused on the structural design and optimization for different applications. The most popular structures used in piezoelectric energy harvesters include cantilever, stack cymbal configuration, diaphragm configuration, and shear mode configuration . The cantilever structure is suitable for low input force, small acceleration, and mid‐high frequencies (tens of Hz or above), but it allows large amplitude/deformation.…”

Energy harvesting technology may be considered an ultimate solution to replace batteries and provide a long-term power supply for wireless sensor networks. Looking back into its research history, individual energy harvesters for the conversion of single energy sources into electricity are developed first, followed by hybrid counterparts designed for use with multiple energy sources. Very recently, the concept of a truly multisource energy harvester built from only a single piece of material as the energy conversion component is proposed. This review, from the aspect of materials and device configurations, explains in detail a wide scope to give an overview of energy harvesting research. It covers single-source devices including solar, thermal, kinetic and other types of energy harvesters, hybrid energy harvesting configurations for both single and multiple energy sources and single material, and multisource energy harvesters. It also includes the energy conversion principles of photovoltaic, electromagnetic, piezoelectric, triboelectric, electrostatic, electrostrictive, thermoelectric, pyroelectric, magnetostrictive, and dielectric devices. This is one of the most comprehensive reviews conducted to date, focusing on the entire energy harvesting research scene and providing a guide to seeking deeper and more specific research references and resources from every corner of the scientific community.

“…Experimental results proved that by incrementing the dimensions of both layers and volume of the proof mass proportionally, the CB's resonant frequency will be greatly reduced to match the ambient vibration frequency. Subsequently, [11] suggested a superior unimorph-configured CB concept by proposing an additional PZT layer to form a composite beam known as the bimorph. It improves the tunable effectiveness of the proof mass, since doubled output peak power is observed when compared to the unimorph.…”

“…where h p is the thickness of each PZT-5A layer. Based on the Euler-Bernoulli beam theory [11], the CB is modelled as a uniform composite beam. As such, when the CB vibrates, the effects of rotary inertia and shear deformation are neglected, while its plane sections are assumed to remain plane.…”

A Novel Self-Powered Dynamic System Using a Quasi-Z-Source Inverter-Based Piezoelectric Vibration Energy Harvester

The use of quasi-Z-source inverters (qZSIs) for DC-DC power conversion applications has gained much recognition when dealing with grid-tied renewable energy resource integrations. This paper proposes a novel self-powered dynamic system (SPDS) involving a piezoelectric vibration energy harvester (PVEH) using qZSI to establish interoperability with a DC load rated at 16.15 mW. Based on uncertain output performances from a piezoelectric cantilever beam (CB), the qZSI-based PVEH serves as a dynamic voltage restoration unit that establishes load-following synchronisation. It uses a proportional-integral based boost controller (PI-based BC) to generate strategic ordering of shoot-through voltage amplification into pulse-width modulation (PWM) gating sequences. The SPDS was modelled using two software based on commercially available product specifications: (i) COMSOL Multiphysics to mechanically design and optimise a CB. (ii) PSCAD/EMTDC to electronically design and integrate the qZSI with the optimised CB, while functioning as a testbed to model the SPDS against arbitrary wind speed and structural vibration frequency data collected from an above-ground mass rapid transit (MRT) train station in Khatib, Singapore. The acquired simulation results have depicted desirable transient responses at respective sub-systems, procuring fast settling-time responses, negligible steady-state error, as well as high efficiencies of 94.07% and 91.64% for the CB and SPDS respectively.

“…The piezoelectric conversion strategy allows energy associated with wide angular motions of the joints in quasi-static conditions to be captured. The piezoelectric effect has been deeply investigated for applications of power generation, and several modeling approaches are available [33][34][35].…”

In the past, human-machine interfacing (HMI) motivated many studies to develop systems and devices that were able to transfer analog commands from the user's body to machines. However, many design solutions are still affected by comfort and performance limitations due to wire communications, long calibration procedures, resistance to hand motions, and power supplies requiring cables or batteries. GoldFinger, the HMI glove introduced in this paper, has the potential to overcome some of these limitations thanks to the integration of advanced materials, miniaturization of components and electronics, and power generation through biomechanical energy harvesting. Hand motions are used to communicate with the machine via a LED tracking system. Then, information is digitalized with dedicated software that also provides the machine microcontroller programming in the C language. Additionally, the battery discharge time is reduced due to the power harvested from integrated piezoelectric transducers, which generate power from finger motions.Index Terms -Human-machine interface, wearable device, image processing, microcontroller, light tracking, machines control, biomechanical energy harvesting, power management.
