Patent number: 11788646Abstract: A three-way (3-way) Micro-Electro-Mechanical Systems (MEMS)-based micro-valve device and method of fabrication for the implementation of a three-way MEMS-based micro-valve which uses a single piezoelectric actuator. The present invention has a wide range of applications including medical, industrial control, aerospace, automotive, consumer electronics and products, as well as any application(s) requiring the use of three-way micro-valves for the control of fluids. The present invention allows for the implementation of a three-way microvalve device and method of fabrication that can be tailored to the requirements of a wide range of applications and fluid types. The microvalve may employ a novel pressure-balancing scheme wherein the fluid pressure balances the actuator mechanism so that only a small amount of actuation pressure (or force) is needed to switch the state of the actuator and device from open to closed, or closed to open.Type: GrantFiled: April 8, 2022Date of Patent: October 17, 2023Assignee: Corporation for National Research InitiativesInventor: Michael Huff

Patent number: 10910185Abstract: The present invention is directed to a method for the fabrication of electron field emitter devices, including carbon nanotube (CNT) field emission devices. The method of the present invention involves depositing one or more electrically conductive thin-film layers onto an electrically conductive substrate and performing lithography and etching on these thin film layers to pattern them into the desired shapes. The top-most layer may be of a material type that acts as a catalyst for the growth of single- or multiple-walled carbon nanotubes (CNTs). Subsequently, the substrate is etched to form a high-aspect ratio post or pillar structure onto which the previously patterned thin film layers are positioned. Carbon nanotubes may be grown on the catalyst material layer. The present invention also described methods by which the individual field emission devices may be singulated into individual die from a substrate.Type: GrantFiled: July 31, 2019Date of Patent: February 2, 2021Assignee: CORPORATION FOR NATIONAL RESEARCH INITIATIVESInventors: Mehmet Ozgur, Paul Sunal, Lance Oh, Michael Huff, Michael Pedersen

Patent number: 8243766Abstract: A laser diode system is disclosed in which a substrate made of a semiconductor material containing laser diodes is bonded to a substrate made from a metallic material without the use of any intermediate joining or soldering layers between the two substrates. The metal substrate acts as an electrode and/or heat sink for the laser diode semiconductor substrate. Microchannels may be included in the metal substrate to allow coolant fluid to pass through, thereby facilitating the removal of heat from the laser diode substrate. A second metal substrate including cooling fluid microchannels may also be bonded to the laser diode substrate to provide greater heat transfer from the laser diode substrate. The bonding of the substrates at low temperatures, combined with modifications to the substrate surfaces, enables the realization of a low electrical resistance interface and a low thermal resistance interface between the bonded substrates.Type: GrantFiled: September 22, 2008Date of Patent: August 14, 2012Inventors: Michael Huff, Jonah Jacob

Publication number: 20050136565Abstract: A method of fabricating a high-aspect ratio micro-mechanical device or system with dimensions that can vary from nanometers to millimeters is disclosed. According to the method, a tool master with a high-aspect ratio, submicron lateral resolution and vertical dimensions substantially corresponding to the vertical dimensions of the device or system is formed. The tool master and a substrate sized for the device or system are heated to a temperature at which the substrate becomes compliant. The heated tool master and substrate are then pressed together so as to imprint the shape and form of the tool master into the substrate. The temperature of the tool master and substrate are then lowered, whereupon the tool master and substrate are separated and cooled to ambient temperature. The tool master can have a plurality of duplications to form a plurality of devices or systems. The substrate is composed of a laminate comprised of a sacrificial layer and a structural layer.Type: ApplicationFiled: December 20, 2004Publication date: June 23, 2005Applicant: Corporation for National Research InitiativesInventor: Michael Huff

Micro-mechanical capacitive inductive sensor for wireless detection of relative or absolute pressure
Publication number: 20050103112Abstract: A micro-mechanical pressure transducer is disclosed in which a capacitive transducer structure is integrated with an inductor coil to form a LC tank circuit, resonance frequency of which may be detected remotely by imposing an electromagnetic field on the transducer. The capacitive transducer structure comprises a conductive movable diaphragm, a fixed counter electrode, and a predetermined air gap between said diaphragm and electrode. The diaphragm deflects in response to an applied pressure differential, leading to a change of capacitance in the structure and hence a shift of resonance frequency of the LC tank circuit. The resonance frequency of the LC circuit can be remotely detected by measuring and determining the corresponding peak in electromagnetic impedance of the transducer.Type: ApplicationFiled: December 13, 2004Publication date: May 19, 2005Applicant: Corporation for National Research InitiativesInventors: Michael Pedersen, Mehmet Ozgur, Michael Huff -
