A Dual Bimorph Assembly
A dual bimorph assembly includes a multilaminar element structure where each elements includes a perforated metal layer, a suffusing conductive ink layer and a transductive assembly. A retainer assembly is provided with conductive tabs and a retainer through connector electrically connects metal layers.
OPTICAL ACTUATOR
An actuator powered by photonic energy comprises a rotor including a material which deforms from a first undeformed state when exposed to electromagnetic radiation to a second deformed state and begins to return to the first state when the electromagnetic radiation is removed. A stationary element is affixed to the rotor. A moving element engaging the stator at least when the rotor is in the second deformed state. Deformation of the deformable material in response to applied electromagnetic radiation is transmitted by the stator to the moving element by friction between the stationary element and the moving element for causing motion of the moving element.
Method of Making a Biomorph Assembly
A method of making a bimorph assembly by stacking a perforated outer bottom metal layer, a transductive element, a perforated central metal layer, a second transductive element, and a perforated outer top metal layer to form a laminar structure, the metal layers and transductive elements being separated by thin conductive ink layers. Applying uniform and continuous pressure to the bottom and top surfaces of the laminar structure. Thermal cycling the laminar structure according to a thermal profile that causes suffusion of the thin conductive ink layers into the metal perforations and the transductive element surface. Removing the pressure from the bottom and top surfaces of the laminar structure and applying an electric field to the central metal layer, the outer top metal layer, and the outer bottom metal layer.
