A nonlinear wideband generator architecture by clamping the cantilever beam generator with a curve
fixture is proposed. Devices with different nonlinear stiffness can be obtained by properly choosing
the fixture curve according to the design requirements. Three available generator types are presented
and discussed for polynomial curves. Experimental investigations show that the proposed
mechanism effectively extends the operation bandwidth with good power performance. Especially,
the simplicity and easy feasibility allow the mechanism to be widely applied for vibration generators
in different scales and environments.
