Patent number: 8174352Abstract: A method for manufacturing or preparing thin-film stacks that exhibit moderate, finite, stress-dependent resistance and which can be incorporated into a transduction mechanism that enables simple, effective signal to be read out from a micro- or nano-mechanical structure. As the structure is driven, the resistance of the intermediate layers is modulated in tandem with the motion, and with suitable dc-bias, the motion is directly converted into detectable voltage. In general, detecting signal from MEMS or NEMS devices is difficult, especially using a method that is able to be integrated with standard electronics. The thin-film manufacturing or preparation technique described herein is therefore a technical advance in the field of MEMS/NEMS that could enable new applications as well as the ability to easily develop CMOS-MEMS integrated fabrication techniques.Type: GrantFiled: June 26, 2009Date of Patent: May 8, 2012Assignees: Cornell University, The United States of America as Represented by the Secretary of the NavyInventors: Jeevak M.

Patent number: 8129072Abstract: A c-axis-oriented HAP thin film synthesized by seeded growth on a palladium hydrogen membrane substrate. An exemplary synthetic process includes electrochemical seeding on the substrate, and secondary and tertiary hydrothermal treatments under conditions that favor growth along c-axes and a-axes in sequence. By adjusting corresponding synthetic conditions, an HAP this film can be grown to a controllable thickness with a dense coverage on the underlying substrate. The thin films have relatively high proton conductivity under hydrogen atmosphere and high temperature conditions. The c-axis oriented films may be integrated into fuel cells for application in the intermediate temperature range of 200-600° C. The electrochemical-hydrothermal deposition technique may be applied to create other oriented crystal materials having optimized properties, useful for separations and catalysis as well as electronic and electrochemical applications, electrochemical membrane reactors, and in chemical sensors.Type: GrantFiled: April 11, 2011Date of Patent: March 6, 2012Assignee: University of RochesterInventors: Matthew Yates, Dongxia Liu

Patent number: 8107156Abstract: Embodiments of the invention are directed to a new type of phase screen, i.e., an opto-electronic device that can convert a distorted incoming optical wavefront into a plane wave or, conversely, transform a plane wave into a prescribed varying output wavefront. The basic concept involves novel binary all-digital MEMS interferometer configurations that can be used to create controlled and arbitrary optical wavefront using only 0,1 amplitude changes followed by differential propagation distances to convert these amplitude variations into controllable and/or continuous phase variations. Clustered pixel notions, such as Floyd-Steinberg, Stucki or other algorithms useful in digital half-tone printing, are simultaneously employed to create controllable grey-level variations as well as continuous phase variations. Desired grey-levels can be obtained wherein each pixel is formed by, e.g., a 3×3 or 5×5 cluster of mirrors.Type: GrantFiled: June 28, 2006Date of Patent: January 31, 2012Assignee: University of RochesterInventors: Nicholas George, Kedar Khare
