This paper presents a piezoelectric energy harvester (PEH) to convert vibrations to electrical power. A unimorph cantilever beam is used to generate voltage on piezoelectric material bonded close to the anchor of the cantilever beam. A 4.85 x 1 x 0.04 cm structural layer with piezoelectric material yields peak-to-peak voltage of 64 V at the resonance frequency of the structure. The empirically confirmed maximum power output is close to 0.5 mW. The results from validation data on the observed structure has been correlated to the simulations in finite element method (FEM) program using piezoelectric analysis tools.

Hybrid Energy Harvesting From Keyboard Beker, Levent; Zorlu, Ozge; Külah, Haluk; Muhtaroglu, Ali (2011-12-02) This paper presents a hybrid energy harvester which combines piezoelectric (PZT) and electromagnetic (EM) transduction mechanisms to scavenge vibration energy from a keyboard. The system comprises of improvements to the dome structure presented in previous studies, in which only PZT transduction mechanism was used to harvest 16.95 mu W of experimentally verified power. An in-house modeling and simulation tool is first introduced in this work to evaluate the integration of EM transduction into the PZT system...
Bimorph piezoelectric energy harvester structurally integrated on a trapezoidal plate Avsar, Ahmet Levent; Şahin, Melin (2016-08-01) A bimorph piezoelectric energy harvester is developed for harvesting energy under the vortex induced vibration and it is integrated to a host structure of a trapezoidal plate without changing its passive dynamic properties. It is aimed to select trapezoidal plate as similar to a vertical fin-like structure which could be a part of an air vehicle. The designed energy harvester consists of an aluminum beam and two identical multi fiber composite (MFC) piezoelectric patches. In order to understand the dynamic ...
Energy harvesting from piezoelectric stacks via impacting beam Özpak, Yiğit; Çalışkan, Mehmet; Department of Mechanical Engineering (2014) Piezoelectric materials can be used for energy harvesting from ambient vibration due to their high power density and ease of application. Two basic methods, namely, tuning the natural frequency to the operational frequency and increasing the operation bandwidth of the harvester are commonly employed to maximize the energy harvested from piezoelectric materials. Majority of the studies performed in recent years focus mostly on tuning the natural frequency of the harvester. However, small deviations in operat...
HARVESTING ELECTRICAL ENERGY FROM MECHANICAL VIBRATION BY PIEZOELECTRIC MATERIALS AND PERFORMANCE OPTIMIZATION Ogunjinmi, Festus; Murat , Fahrioğlu; Electrical and Electronics Engineering (2022-9-2) The energy conversion performance of piezoelectric cantilever-beam energy harvesters (PCEH) is improved by developing and designing a novel. A rectangular hole is located in the middle of the metal substrate. Using the mathematical model of the PCEH, the mathematical expression of the following is derived as the eigenfrequency, displacement of the proof mass, and output voltage and power level achieved due to displacement of the cantilever carrying the piezoelectric material. We analyze the eigenfrequ...
