Abstract
A method of electromechanical energy harvesting includes sensing electrical current generated by relative movement of a coil and a magnetic flux source produced by movement of a cantilevered beam in response to ambient vibration energy, determining a vibration characteristic of the ambient vibration energy, and adjusting an effective flexible length of the cantilevered beam as a function of the vibration characteristic and the sensed electrical current.
