导电聚合物驱动器电化学机械特性的研究

采用自行搭建的导电聚合物驱动器弯曲特性测试实验系统，研究其电化学机械特性。对不同长度的驱动器施加0~1V低电压，测量其顶端弯曲变形量；通过分析驱动器弯曲位移与电压的关系及位移与频率的关系，建立电机械转换模型。实验测试结果表明，电压与驱动器顶端力成线性关系；当电压为0.8V、采样周期为0.02s时，随着频率的增大，驱动器的弯曲位移逐渐减小。最后通过不同尺寸驱动器举起重物，验证了驱动器宽度越大，顶端弯曲力越大；驱动器长度越长，顶端弯曲力越小。

Study on Electrochemical-mechanical Characteristics of Conductive Polymer Actuator

The bend characteristics testing experimental system was set up by actuator to study the electrochemical-mechanical characteristics. The bending deformation was measured by applying low voltage(0 ~ 1V) to the actuator with different lengths. The relationship among the bending displacement, the voltage and the voltage frequency was analyzed. The electric-mechanical transfer model was established based on the experimental results. The results show that the voltage and the bending force are in a linear relationship. When the voltage is 0.8V and sampling period is 0.02s, the bending displacement of the actuator decreases gradually with the increase of the frequency. Furthermore, it is verified by lifting the weights of the drive of different sizes，the larger the width of the drive, the larger the bending force, and the longer the length, the smaller the bending force.
