On Mechanical Modeling of Cantilevered Piezoelectric Vibration Energy Harvesters
Cantilevered beams with piezoceramic (PZT) layers are the most commonly investigated type of vibration energy harvesters. A frequently used modeling approach is the single-degree-of-freedom (SDOF) modeling of the harvester beam as it allows simple expressions for the electrical outputs. In the literature, since the base excitation on the harvester beam is assumed to be harmonic, the well known ...
متن کاملTemperature effects on output power of piezoelectric vibration energy harvesters
The performance of piezoelectric vibration energy harvesters was studied as a function of environment temperature. The devices fabricated by soft or hard PZTs were used to investigate the effect of material parameters on the thermal degradation of the devices. PZT MEMS device was also prepared and compared with the bulk devices to investigate scaling effect on the thermal degradation. All devic...
متن کاملVIBRATION ENERGY HARVESTERS OF LEAD-FREE (K,Na)NbO3 PIEZOELECTRIC THIN FILMS
In this study, we fabricated piezoelectric energy harvesters composed of lead-free (K,Na)NbO3 (KNN) thin films and compared the power generation performance with PZT-thin film energy harvesters. Both of the piezoelectric thin films were deposited on Pt/Ti/Si cantilevers by rf-sputtering. The KNN and PZT thin films had perovskite structure, and showed the relative dielectric constants of 744 and...
متن کاملDesign and Optimization of Wideband Multimode Piezoelectric MEMS Vibration Energy Harvesters
To enlarge operating frequency bandwidth of the multimode energy harvesters, nonlinearity characteristics has to be well presented by the system configuration. Therefore, the conventional optimization techniques, which are solely based on human observation, are highly difficult and somehow impossible. In this paper we propose an efficient optimization technique for automating the design of nonl...
متن کاملGenetic Algorithm Optimization for Mems Cantilevered Piezoelectric Energy Harvesters
A design optimization based on genetic algorithms for increasing power output performance of MEMS piezoelectric cantilevered energy harvesters has been performed. By employing genetic algorithms, the piezoelectric energy scavenging system with optimized shape and lateral geometries of a unimorph cantilever beam and a proof mass is simulated to achieve a power response improvement of ~1.8× in co...
