Energy harvesting holds great potential to achieve long-lifespan self-powered operations of wireless sensor networks, wearable devices, and medical implants, and thus has attracted substantial interest from both academia and industry. This paper presents a comprehensive review of piezoelectric energyharvesting techniques developed in the last decade. The piezoelectric effect has been widely adopted to convert mechanical energy to electricity, due to its high energy conversion efficiency, ease of implementation, and miniaturization. From the viewpoint of applications, we are most concerned about whether an energy harvester can generate sufficient power under a variable excitation. Therefore, here we concentrate on methodologies leading to high power output and broad operational bandwidth. Different designs, nonlinear methods, optimization techniques, and harvesting materials are reviewed and discussed in depth. Furthermore, we identify four promising applications: shoes, pacemakers, tire pressure monitoring systems, and bridge and building monitoring. We review new high-performance energy harvesters proposed for each application.

“…Vibration harvesting from engine vibrations was demonstrated with a cantilever harvester with 155 mm length that was installed on the vehicle engine and tested in various engine speeds. [61] The system is shown in Figure 7a. It is found that in frequency match condition of around 2000 rpm engine speed, more energy can be harvested.…”

Piezoelectric energy harvester is the device which uses the external force acting on the piezoelectric elements to generate energy. Usually, this technology is used to convert the ambient waste energy into the usable electrical energy. The mechanism of piezoelectric energy harvester is based on the direct piezoelectric effect. When the harvester is subjected to the stresses, charges will be generated on the materials surface proportionally. When connected to external circuit, the charges will lead to current flow through the load. Therefore, the piezoelectric material in this operation is essentially a voltage, current, charge, or power source. Sometimes, the piezoelectric energy harvester is also called energy scavenger or power generator. Conventionally, the direct piezoelectric effect is applied in piezoelectric sensors, for example, force, pressure and acceleration sensors. In recent decades, the application of direct piezoelectric effect on energy harvester has drawn increasing attention due to a few reasons: first, this is the response of energy crisis. There are increasing concerns on the energy depletion and the need for carbon emission reduction. Therefore, interests on replacement energy over the existing fossil fuel energies arise. Second, environment issue calls for clean, green, sustainable and reusable energy. The present era of industrialization is most advanced than ever in the history, however, the release of waste also brings significant environmental problems. Last but not least, in recent decades, the development of smart devices is rapid and adoption is widespread. Many of them requires low power or powerless for applications such as medical, mobile, or remote devices, where the change of battery is not convenient, high labor cost, inaccessible, or with great hassles.So far there are different kinds of ways for energy harvesting, for example, wind power, hydraulic power, solar power and thermal power etc. Piezoelectric energy harvester is materials based power generator. It features low profiles, micro to meso scale, flexible in structures designs, long life span, and thus is a good candidate for small devices applications. The power level of an energy harvester usually falls in the order of nW, μW, mW, or W. [1] In the process or energy harvesting, the mechanical energy is converted into the electric energy. The energy output of the device is related to a number of parameters. Figure 1a is the equivalent circuit model of the piezoelectric energy harvester,

Khalatkar and Gupta (2017) designed and developed a piezoelectric energy harvester to harvest energy from engine vibrations at low frequencies. Rezaei-Hosseinabadi et al (2015) developed a piezoelectric beam harvester, coupled with a wind turbine.…”

A rotary-type energy harvester for the applications having space restrictions has been designed and developed to harvest the energy from rotary motion system. The rotation kinetic energy is converted into electrical energy through a lead zirconate titanate patch, which is strained by magnetic force. Most of the researchers used d31 mode of the piezoelectric material of such conversion. Some researchers have explored d33 mode harvester with piezo patch along the circumferential direction. In this article, d33 mode of harvesting with radial direction piezo patch has been proposed. Mathematical and finite element models are developed to calculate the harvested energy. The results are experimentally verified. The average output power of 14.48 nW is generated corresponding to the magnetic force of 0.3126 N and rotational speed of 2100 r/min. The results from the mathematical and finite element models are observed to be consistent with the experimental results. Such harvester will be useful for the applications having space limitations such as self-power generation in an artillery shell and rotary projectile.
