- *Abstract
-
Vibration energy harvesters are suitable for various applications such as in autonomous sensors. Currently, many such harvesters are used; however, most of these harvesters are associated with potential limitations. One such harvester used is a piezoelectric device, which shows brittle cantilever and degraded polarization after a certain operational time. This approach enables the development and use of a novel high energy density vibration energy harvesting system with a high-┬╡ material.
