- A novel design method for a two degree-of-freedom (2DOF) energy harvesting device is studied.
The energy harvesting device is modelled as a rigid body supported by two parallel sets of springs and
dampers. The impedance expression for the model has been developed by utilizing the concept of the
inerter. The proposed design method deals with tuning two resonant peaks and equalizing the
harvested power at those frequencies. As a result, the proposed energy harvesting device is
particularly effective at two frequencies and has increased bandwidth as well as reduced size and
weight in comparison with previous SDOF devices. A numerical design example is provided to show
effectiveness of the proposed method.
