Armando Rua has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Microactuators based on insulator-to-metal transition materials and method of using the same
    Patent number: 8835861
    Abstract: The invention utilizes the changes in physical properties of materials during a solid-solid phase transition in order to actuate microactuators. The substantial changes in properties during insulator-to-metal transitions (IMTs) of some materials are useful for controlling purposes. Methods of using the microactuators are also explained.

  • Bimorph cantilever arrangement and applications thereof
    Patent number: 8440973
    Abstract: The invention utilizes the changes in physical properties of materials during a solid-solid phase transition in order to enhance the sensitivity of cantilever IR detectors. The substantial changes in properties during insulator-to-metal transitions (IMTs) of some materials are useful for controlling purposes according to the invention. A cantilever arrangement is provided with a cantilever being coated with an insulator-to-metal transitions (IMTs) material. Bending of the cantilever is achieved when the temperature of the (IMTs) material is within its phase transition temperature range. A Focal Plane Array (FPA) for detecting Infrared (IR) radiation including the cantilever arrangement of the invention is also proposed.
