Axial motion characterization of a helical ionic polymer metal composite actuator and its application in 3-DOF micro-parallel platforms

Popis výsledku v původním jazyce

In this work, a helical ionic polymer metal composite (IPMC) was fabricated in a mold with helix grooves. The axial actuation behavior of the helical IPMC actuator was observed. The experimental results showed that as the voltage increased and the frequency decreased, the axial displacement, axial force, and electric current of the actuator all increased. Compared with square wave and sinusoidal signals, the actuator exhibited the most satisfactory motion under the direct current (DC) signal. For the electrochemical test, as the scanning rate decreased, the gravimetric specific capacitance increased. Within a suitable voltage range, the actuator was chemically stable. COMSOL Multiphysics software was used to model and analyze the helical IPMC actuator. The simulation data obtained were in good agreement with the experimental data. Finally, by using three helical IPMC actuators as driving components, an innovative three-degree-of-freedom (3-DOF) micro-parallel platform was designed.
