ABSTRACT:
An actuator housing unit for a system of layered surfaces, comprising an activated primary surface having a physical shape capable of change when activated by an electrical, chemical, or light stimulus, to expand and exert force or pressure or contract and remove force or pressure, upon activation or deactivation, to move or keep matter within the housing by direct or indirect contact.
