Patent number: 10850510Abstract: Methods and apparatuses for controlling aerosol streams being deposited onto a substrate via pneumatic shuttering. The aerosol stream is surrounded and focused by an annular co-flowing sheath gas in the print head of the apparatus. A boost gas flows to a vacuum pump during printing of the aerosol. A valve adds the boost gas to the sheath gas at the appropriate time, and a portion of the two gases is deflected in a direction opposite to the aerosol flow direction to at least partially prevent the aerosol from passing through the deposition nozzle. Some or all of the aerosol is combined with that portion of the boost gas and sheath gas and is exhausted from the print head. By precisely balancing the flows into and out of the print head, maintaining the flow rates of the aerosol and sheath gas approximately constant, and keeping the boost gas flowing during both printing and shuttering, the transition time between printing and partial or full shuttering of the aerosol stream is minimized.Type: GrantFiled: December 18, 2019Date of Patent: December 1, 2020Assignee: Optomec, Inc.Inventors: Kurt K. Christenson, Michael J. Renn, Jason A. Paulsen, John David Hamre, Chad Conroy, James Q. Feng

Patent number: 8132744Abstract: A miniaturized aerosol jet, or an array of miniaturized aerosol jets for direct printing of various aerosolized materials. In the most commonly used embodiment, an aerosol stream is focused and deposited onto a planar or non-planar target, forming a pattern that is thermally or photochemically processed to achieve physical, optical, and/or electrical properties near that of the corresponding bulk material. The apparatus uses an aerosol jet deposition head to form an annularly propagating jet composed of an outer sheath flow and an inner aerosol-laden carrier flow. Miniaturization of the deposition head facilitates the fabrication and operation of arrayed deposition heads, enabling construction and operation of arrays of aerosol jets capable of independent motion and deposition. Arrayed aerosol jets provide an increased deposition rate, arrayed deposition, and multi-material deposition.Type: GrantFiled: April 15, 2010Date of Patent: March 13, 2012Assignee: Optomec, Inc.Inventors: Bruce H. King, Michael J. Renn, Jason A. Paulsen

Cobalt ferrite based magnetostrictive materials for magnetic stress sensor and actuator applications
Patent number: 7326360Abstract: Magnetostrictive material based on cobalt ferrite is described. The cobalt ferrite is substituted with transition metals (such manganese (Mn), chromium (Cr), zinc (Zn) and copper (Cu) or mixtures thereof) by substituting the transition metals for iron or cobalt to form substituted cobalt ferrite that provides mechanical properties that make the substituted cobalt ferrite material effective for use as sensors and actuators. The substitution of transition metals lowers the Curie temperature of the material (as compared to cobalt ferrite) while maintaining a suitable magnetostriction for stress sensing applications.Type: GrantFiled: July 23, 2004Date of Patent: February 5, 2008Assignee: Iowa State University Research Foundation, Inc.Inventors: David C.
