  • Tunable vibration energy harvester and method
    Patent number: 8866316
    Abstract: In one embodiment, an energy harvester is provided. The energy harvester 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.
