“…The beam is contactlessly plucked once per cycle by the magnetic force provided by the driving magnet. This mechanism avoids the situation of an overstressed piezoelectric beam caused by direct impacts [30,31]. Considering the brittle characteristic of piezoelectric materials, the contactless plucking enhances the reliability of the device by reducing the possibility of the degradation of the materials.…”

“…They obtained maximum power of 6.4 mW at a shaft speed of 138 rad/s [34]. This rotary type energy harvester is also useful for the wind energy harvesting using impact-induced resonance operation [35]. The off-resonance operation with the high power output of the piezoelectric energy harvester can achieve more practical ways to use the various applications around it.…”

Abstract:Energy harvesting is the most effective way to respond to the energy shortage and to produce sustainable power sources from the surrounding environment. The energy harvesting technology enables scavenging electrical energy from wasted energy sources, which always exist everywhere, such as in heat, fluids, vibrations, etc. In particular, piezoelectric energy harvesting, which uses a direct energy conversion from vibrations and mechanical deformation to the electrical energy, is a promising technique to supply power sources in unattended electronic devices, wireless sensor nodes, micro-electronic devices, etc., since it has higher energy conversion efficiency and a simple structure. Up to now, various technologies, such as advanced materials, micro-and macro-mechanics, and electric circuit design, have been investigated and emerged to improve performance and conversion efficiency of the piezoelectric energy harvesters. In this paper, we focus on recent progress of piezoelectric energy harvesting technologies based on PbZr x Ti 1´x O 3 (PZT) materials, which have the most outstanding piezoelectric properties. The advanced piezoelectric energy harvesting technologies included materials, fabrications, unique designs, and properties are introduced to understand current technical levels and suggest the future directions of piezoelectric energy harvesting.

“…Also, a simulation analysis of four different interface circuits with non-standard sinusoidal equivalents was performed using Matlab and PSpice. For the equivalent voltage source in the model, the damped sinusoidal signal source and random signal source used were based on the experimental voltage in [15] and [16]. To present the framework for the simulation analysis, we introduce the basics of energy harvesting, including the equivalent circuit model, four passive interface circuits, and non-standard sinusoidal signals.…”

IntroductionMicro-energy harvesting has been widely studied because of the development of wireless sensor networks. Various energy harvesting techniques, such as solar energy, thermal energy, and vibration energy have been investigated to eliminate dependence on batteries or wires [1][2][3][4][5]. The electromagnetic, electrostatic, and piezoelectric transition mechanisms are the main methods for harvesting vibration energy. In particular, piezoelectric vibration energy harvesting has received significant attention for its high power density, simple structure, and ability to operate without producing pollution [6].A piezoelectric energy harvesting system mainly consists of a mechanical structure and interface circuits. With regard to the mechanical structures in such systems, cantilever beams with patches of piezoelectric materials have been extensively investigated [7,8]. The performance of the energy generated by piezoelectric elements with harmonic excitations has been studied widely. Recently, flow-induced piezoelectric energy harvesting has gained much attention. Some of the trends in piezoelectric energy harvesting are multi-directional wideband technology [9] and flow-induced or impact-induced piezoelectric energy harvesting [10]. In these systems, the electricity generated by piezoelectric cantilever beams is not sinusoidal. Meanwhile, the mechanical structures for collecting multi-direction energy and flow-induced piezoelectric energy have been widely investigated. Experiments on many mechanical structures under different conditions have been performed to evaluate the performance of different structures. With regard to interface circuits, the standard interface circuit, series synchronized switch harvesting interface circuit (S-SSHI), parallel synchronized switch harvesting interface circuit (P-SSHI), and synchronized charge extraction interface circuit (SCE) have been analyzed in detail, and all involve standard sinusoidal equivalent sources [11][12][13]. However, the performance of different interface circuits with a non-standard sinusoidal equivalent source has been minimally investigated. Many experiments have been performed in ideal laboratory environments where piezoelectric elements were subjected to harmonic excitations; thus, numerous analyses involving sinusoidal signals have been made.
