本文综述了一种称为PolyPowerTM的叠层介电电活性聚合物(DEAP)薄膜用于能量回收的可行性研究。薄膜中的最大应变被限制在<；35%，最大施加电压目前被限制在<；3000 V，比已经在基于DEAP的能量收集应用中使用的丙烯的应变和电压要小得多。这项工作将检查使用PolyPowerTM可以产生的电能的数量，以提供对(A)使用该材料进行能量清除的实用性和(B)突出可行的清除应用的洞察。设计了一台试验台，并进行了一系列实验，以研究使用DEAP材料的能量清除。在充电阶段的最大外加电压分别为1.2kv、1.5kv和1.8kv时，研究了5%、10%和15%三种不同的初始机械应变水平。对于九个实验中的每个实验，确定了可用于清除的电能总量，并将结果与能量清除循环的模型进行了比较。虽然讨论了不同类型的循环连续运行的相关利弊，但这项工作并未涉及扫气电能的回收。
A feasibility study into the appropriateness of using a laminated dielectric electro active polymer (DEAP) film, called PolyPowerTM, for energy scavenging purposes is reviewed in this work. The maximum strain in the film is limited to < 35% and the maximum applied voltage is currently limited to < 3000 V, strains and voltages much less than those applied to acrylics already utilised in DEAP-based energy harvesting applications. This work will examine the amount of electrical energy that can be produced using PolyPowerTM to provide insight into (a) the practicality of using the material for energy scavenging and (b) to highlight feasible scavenging applications. A test rig was designed and a series of experiments carried out to investigate energy scavenging using the DEAP material. Three different levels of initial mechanical strain, 5%, 10% and 15% were investigated with three different levels of maximum applied voltage during the charging stage, 1.2 kV, 1.5 kV and 1.8 kV. For each, of the nine, experiment the total amount of electrical energy available for scavenging was determined and results compared with a model of the energy scavenging cycle. The recovery of the scavenged electrical energy was not addressed in this work, though the relevant advantages and disadvantages of different types of continuous operation of the cycle are discussed.
