Optimal piezoelectric beam shape for single and broadband vibration energy harvesting: modeling, simulation and experimental results

Harvesting energy from the surroundings has become a new trend in saving our environment. Among the established ones are solar panels, wind turbines and hydroelectric generators which have successfully grown in meeting the world’s energy demand. However, for low powered electronic devices; especiall...
