Energy harvesting from wind by a piezoelectric harvester
Engineering Structures, 2017Abstract A novel wind power harvester using piezoelectric effect is developed. This engineering structure device employs a wind turbine that extracts kinetic energy from the wind and converts it into the rotational motion of a shaft. The rotational shaft is connected to a Scotch yoke mechanism that is used for converting the rotational motion into ...

Piezoelectric fibers for energy harvesting.
The Journal of the Acoustical Society of America, 2010Most energy harvesting devices rely on traditional piezoelectric materials integrated in structures subjected to mechanical vibrations. A new kind of commercially available composite sensors consists of several PZT fibers embedded in a passive polymer matrix with interdigitated electrodes deposited on the polymer. The main advantage of these sensors is

On the Performance Improvement of Piezoelectric Energy Harvesters [PDF]
International Journal of Mechanical Engineering and Robotics Research, 2016 Among the available solutions to harvest energy from vibrating and non-vibrating sources, piezoelectric bimorphs seem to be a suitable choice due to their capability to directly convert applied strain energy into usable electric power. This work reviews the techniques adopted to increase the specific power per unit of volume of piezoelectric scavengers.

Piezoelectric MEMS Energy Harvesters
Volume 2: Mechanics and Behavior of Active Materials; Integrated System Design and Implementation; Bioinspired Smart Materials and Systems; Energy Harvesting, 2014The development of self-powered wireless microelectromechanical (MEMS) sensors hinges on the ability to harvest adequate energy from the environment. When solar energy is not available, mechanical energy from ambient vibrations, which are typically low frequency, is of particular interest.

Energy harvesting with piezoelectric cantilever
2008 IEEE Ultrasonics Symposium, 2008Energy harvesting with the piezoelectric cantilever was studied under vibration environment. A theoretical model of piezoelectric cantilever was developed to determine the magnitude of power. The results predicted by the theoretical model were validated by the experimental data.

Energy Harvesting With a Piezoelectric THUNDER
Volume 4B: Dynamics, Vibration, and Control, 2015In this work the energy harvesting performance of a piezoelectric curved energy generator (THUNDER) is studied via experimental and analytical methods. The analytical model of the THUNDER is created based on the linear mechanical electrical constitutive law of the piezoelectric material, the linear elastic constitutive law of the substrate, and the ...
