基于可变电容机制研究电介质电活性聚合物的能量产生能力。通过考虑充电过程中的能量损失来分析一个周期的能量转换，其中产生的能量定义为输出电能与总输入电能之间的差值。在两种充电模式和不同拉伸率下进行实验，以研究它们对能量转换的影响。通过边拉伸充电模式和低拉伸率，能量转换效率高达18.3%，能量密度为18.9 mJ/g，每循环功率为3.775 mW/g。
Dielectric electroactive polymers are studied for their energy generating ability based on a variable capacitance mechanism. Energy conversion for one cycle is analyzed by considering the energy loss in the charging process, where generated energy is defined as the difference between output and total input electrical energy. Experiments are conducted under two charging modes and different stretch rates to investigate their effect on the energy conversion. Energy conversion efficiency of up to 18.3% is achieved with charging-while-stretching mode and a low stretch rate, with an energy density of 18.9 mJ/g and power of 3.775 mW/g per cycle obtained.
