Abstract

Electrostrictive polymers energy harvesters are an emerging technology that promises high power density, low cost and scalability. Power can be produced simply by stretching and contracting a polymer film. At present, the investigation of using electrostrictive polymers for energy harvesting (a conversion of mechanical to electrical energy) is beginning to show potential for this application. The relative energy gain basically depends in the current induced by the mechanical strain and frequency. Previous work of some of the co-authors, has indicated that one can measure the dielectric constant, the Young modulus and the electrostrictive coefficient of a polymer film by the determination of the current flowing through the sample when simultaneously driven by electrical field and mechanical excitation. This paper investigates the effects of this method for different frequencies for both electrical field E and strain in order to develop a more in-depth understanding of the changes in system response for increased current and energy harvesting. Results relating amplitude strain and the frequency for electrical field provide a framework for developing energy harvesting techniques which improve the overall performance of the system. Experimental data indicate that the current induced with polymer is proportional with the change in frequency of the deformation. In the present paper the theory is detailed and the simulation results are compared with experimental ones. Good agreements are found between both approaches..
