An intelligent material unit formed of an intelligent gel encapsulated within an enclosure. When the gel is actuated by a change in temperature thereof, such as heat and/or by an externally applied field such as an electrical current, electric field, magnetic field, ultrasonic energy (or sonic), microwave energy, a laser beam or a combination thereof, at least a portion of the wall of the container or enclosure is deformed to perform a mechanical function or operation; such as to valve a fluid or cause movement of the container and gel through a fluid or in a passageway. The container may be a thin-skinned flexible plastic, such as an elastomer and may be elongated or sausage-like in shape, or strip-like. It may be free travelling, cantilever-supported or otherwise mounted or attached to a device, machine or element. It may also carry a drug for delivery therefrom at a select location and time.
