Mechanical Property and Power Generation Application Research on Dielectric Electro Active Polymer

Abstract:

According to the energy transformation of the dielectric electro active polymer(DEAP) from mechanical energy to electric power,the electric power generation mechanism is studied on the DEAP.The mathematical model for simulating the deformation of dielectric elastomer is set up on the basis of the MooneyRivlin model,and the dynamic characteristic of the material is discussed under different working conditions.Meanwhile,DEAP is analyzed in the staticelectric field on the forces,scavenged energy equation and motion equation.With the Danfoss DEAP material,the prototype is set up for harvesting energy from the wind.Quantitative experiments and research as well as detailed analysis show that the DEAP can generate the electric energy harvesting from the environmental sources.
