Beschreibung:
<jats:p>IPMC (Ionic Polymer Metal Composite) is promising candidate actuator for bio-related applications mainly due to its biocompatibility, soft properties and operation in wet condition. In this paper, a new actuator will be presented. The tubular actuator, based on the concept of tip-displacement of IPMC actuator and capable of generating bending of tube with surface outside electrodes, was proposed and studied experimentally. The actuator is a Nafion tube consisting of an even number of Pt segments along the length, which are plated outside of tube surface, and the Pt segments act as electrodes to apply the driving voltage. The experimental data measured on prototype actuators prove the proposed concept of bending depend on the shape of Nafion. Show that the actuator functions well both displacement and force.</jats:p>
