Design and analysis of a piezoelectric energy harvester for rotational motion system

Comparison of PZN-PT, PMN-PT single crystals and PZT ceramic for vibration energy harvesting

“…Batteries are bulky, suffer from the environmental issue, and need to be recharged or replaced which are unacceptable for applications in harsh, large-area or inaccessible environments. The energy harvesting concept was therefore proposed to power such standalone systems by harvesting and converting ambient mechanical energy into electrical energy [1][2][3][4].…”

Soft and Hard Piezoelectric Ceramics and Single Crystals for Random Vibration Energy Harvesting

“…In the existing literatureofpiezoelectrice nergy harvesting, linear and nonlinear beams and plates with piezoelectric layers have been the main focus of the mainstream research. [7][8][9][10][11][12][13][14][15][16][17][18][19] Numerous articles have reported the development of analytical and numerical electromechanical models of cantilevered energy harvesters for the optimal mechanical and electrical conditions [9,11,[20][21][22] with the assumption that the vibration input to the harvesteri so fd eterministic type,o ften as simple as harmonic excitation at resonance. [7,12,23,24] However, in most applications,a mbientv ibrations are manifested in non-deterministicf orms.W hen compared with the amount of published research on piezoelectric energy harvesters with deterministic harmonic input, the existinge fforts on piezo-electric energy harvesting from broadband and band-limited random vibrations are very limited.…”

A methodology for low-speed broadband rotational energy harvesting using piezoelectric transduction and frequency up-conversion

“…The progress and research topics on vibration energy harvesting are summarized in several comprehensive review papers, such as vibration energy harvesting from human motion and machine operation in [4,5], nonlinear mechanisms for broadband energy harvesting in [6,7] and functional materials for energy conversion in [8]. However, as another type of kinetic energy, rotational energy is less investigated and harnessed for power supply, but has unique dynamics that would be beneficial to some applications, including tire pressure sensing [9,10], condition monitoring of rotating machines [11,12] and fluid flow energy harvesting using miniature turbines [13].…”
