Abstract EN
It has been proven that tapering the piezoelectric beam through its length optimizes the power extracted from vibration based energy harvesting.
This phenomenon has been investigated by some researchers using semianalytical, finite element and experimental methods.
In this paper, an exact analytical solution is presented to calculate the power generated from vibration of exponentially tapered unimorph and bimorph with series and parallel connections.
The mass normalized mode shapes of the exponentially tapered piezoelectric beam with tip mass are implemented to transfer the proposed electromechanical coupled equations into modal coordinates.
The steady states harmonic solution results are verified both numerically and experimentally.
Results show that there exist values for tapering parameter and electric resistance in a way that the output power per mass of the energy harvester will be maximized.
Moreover it is concluded that the electric resistance must be higher than a specified value for gaining more power by tapering the beam.
