Abstract: An implantable electrode array includes an elongated carrier (20) and a plurality of electrodes mounted within the carrier. A actuator adjusts the curvature of the carrier and can be controlled by varying an electric potential applied to the actuator. The actuator is based on an electrochemical cells and may be a conducting polymer based actuator.

Abstract: The present invention concerns movement facilitation devices for facilitating movement between a first portion of a first object and a second portion of the first object. One or more of the movement facilitation devices may be combined to form a movement device for facilitating movement of at least one joint or limb of a patient's body. One form of a movement device according to the invention is a glove which at least partially encloses the joint or limb. The invention also encompasses systems for applying Continuous Passive Motion therapy to a joint or limb of a patient using the devices of the invention. The invention also encompasses the use of shape memory materials and of conducting polymers in the devices and systems of the invention, as well as the design of force transducers and actuators that may be used in the devices.

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.

Abstract: A feedback device for detecting a mechanical input and providing a feedback indication. For example, a wearable biomechanical feedback device that has an electrically conductive fabric sensor that can be closely fitted to a limb. Movement of the limb causes strain on the fabric sensor which alters its electrical impedance and triggers the feedback indication.
