ABSTRACT:
An integrated multi-mode transducer for use with a member to control movement of the member. The transducer includes an active element adaptable to engage the member. The active element is changeable from a first shape to a second shape in the presence of an electromagnetic field. Apparatus including a controller is provided for producing an electromagnetic field which extends through at least a portion of the active element to change the shape of the active element and thus exert a force on the member, for sensing movement of the member and for damping movement of the member. A method for using the transducer is provided.
