PROBLEM TO BE SOLVED: To provide a tunable vibration energy harvester.SOLUTION: An energy harvester 12 includes an energy conversion device configured to convert vibrational energy to electrical energy, a mass coupled to the energy conversion device, and at least one biasing mechanism coupled to the mass. The biasing mechanism is selectively adjustable, and selectively adjusting the biasing mechanism adjusts a resonance frequency of the energy conversion device and the mass. |
