1. An electromechanical actuator for effecting a desired action, comprising:
- a conducting polymer and a conductor for conducting voltage along the polymer from one end region of the polymer to an opposite end region of the polymer;
wherein the conductor is arranged in a concertina pattern along the polymer for extension and retraction with expansion and contraction of the polymer, and extends along the polymer from the one end region to the opposite end region.

Abstract
An electromechanical actuator comprising an inherently conducting polymer and a conductor for conducing voltage along the polymer from a first end region thereof. The conductor is adapted for axially extending and contracting with axial expansion and contraction of the polymer. In one form, the conductor is in the form of a helix embedded in the polymer and extends along substantially the entire length of the polymer. Also disclosed is a method for manufacture of the electromechanical actuator.
