Vibration energy harvesting is a type of technology that converts mechanical energy from vibrating sources into electrical energy. It works by using a transducer to transform the vibration energy of a machine into electricity. This electricity can then be stored or used to power electronic devices. Vibration energy harvesting is becoming increasingly popular due to its ability to generate power from sources that would otherwise be wasted, such as the vibrations caused by traffic, seismic activity, or industrial machinery.
