Finding a way to mass produce the springs for a commercial, large scale use may be only a short way off, with the testing for failure the largest concern in this area. Making the small actuators individually does not take much time and can definitely be an automated process.  The challenge comes in coiling the actuators with the thermal elements of copper or nichrome, or in painting a completed coil with silver or other such conductive material. Coiling the thermal element can lead to uneven spacing of the metal filament, or coils that are too tight because of the filament, or in the case of using conductive paint, raise the overall cost of production of the filaments, making them not as cost-effective choices for certain projects.

In the future, the coils will be an asset in nearly every field, from being low cost for delicate but disposable type robotics, to sturdy space faring robotics that need to operate in the vacuum of space where the environment may be particularly suited for this type of actuator. With the simplicity and strength that the actuators exhibit, they will make excellent choices in the use of prosthetics and other types of mechanical rehabilitative devices as well.
