摘要：

According to the experimental analysis on the energy transformation of Dielectric Electro Active Polymers (DEAPs) from mechanical energies to electric powers in a static-electric field, its mechanism of electric power generation was studied. The electric energies generated from DEAP were quantitatively researched, then a mathematical model on the DEAP's deformation property was established by using the strain energy function theory from the Yeoh model, Mooney-Rivlin model and Ogden model. Furthermore, the mechanical characteristics of DEAPs were discussed in different deformations, and the scavenged energy equation and motion equation were deduced. Finally, on the basis of the power generation mechanism of DEAPs, the prototype of a micro-wind-powered generator adopting the DEAP materials from Danfoss was developed. Experimental results show that the scavenging energy is 13.7 mJ in one cycle when the DEAP is in a strain of 10% and an applying voltage of 1 200 V. These experiments lay the theoretic foundation for actuators, sensors and micro-generators of DEAPs.
