Publication number: 20130207513Abstract: This invention provides an electromechanical device comprising an active material comprising a metal oxide such as Ce0.8Gd0.2O1.9 wherein the elastic modulus of metal oxide can be modulated by applying external electric field. The Ce0.8Gd0.2O1.9 layer in a substrate \ electrode \Ce0.8Gd0.2O1.9 \ electrode structure or conductive substrate \Ce0.8Gd0.2O1.9 \ electrode structure develops a stress upon applying an electric field. This invention provides methods for tailoring the elastic modulus of materials using an electric field for the generation of an electromechanical response.Type: ApplicationFiled: October 5, 2011Publication date: August 15, 2013Inventors: Igor Lubomirsky, Roman Korobko, Anna Kossoy, Harry L.

Patent number: 8419984Abstract: A film is presented having super-pyroelectric properties. The film comprises nano-sized grains being in a ferroelectric phase and having at least three different crystallographic variants defining at least two polycrystalline macro-domains. The film is shaped to define at least one film region with the macro-domains of a predetermined shape and different orientations of crystallographic axes with respect to the film's surface, thereby enabling to apply a temperature change to the film to induce movement of the polycrystalline macro-domains boundaries enabling super-pyroelectric properties.Type: GrantFiled: June 17, 2007Date of Patent: April 16, 2013Assignees: Yeda Research and Development Company Ltd., University of MarylandInventors: Igor Lubomirsky, Vera Lyahovitsky, Alexander L.

Patent number: 8354583Abstract: A solar energy conversion system is presented. The system comprises at least one waveguide arrangement having at least one light input respectively. The waveguide arrangement comprises a core unit for passing input solar radiation therethrough and a cladding material arrangement interfacing with the core therealong. The cladding material arrangement is configured as an array of spaced-apart solar cells arranged along the core unit and having different optical absorption ranges, such that an interface between the waveguide core and the cladding arrangement spectrally splits the photons of the input solar radiation by causing the photons of different wavelengths, while passing through the core unit, to be successively absorbed and thereby converted into electricity by the successive solar cells of said array.Type: GrantFiled: May 30, 2007Date of Patent: January 15, 2013Assignees: Bar Ilan University, Yeda Research and Development Company Ltd, The Regents of The University of CaliforniaInventors: Arie Zaban, David Cahen, Igor Lubomirsky, Oscar M. Stafsudd

Patent number: 7148478Abstract: A method and device are presented for measuring the electrical properties of a specimen. The specimen is excited with high energy radiation to cause emission of internal charged particles from the specimen. Electrical power is supplied to a circuit, that is formed by the specimen and any added component connected to a back contact of the specimen. The electric power supply includes at least one of the following: irradiating the circuit with low energy charged particles; subjecting the circuit to an external field of the kind affecting the flux of emitted internal charged particles, and supplying a bias voltage to the back contact of the specimen. During the power supply to the specimen, at least one of the following is carried out: an electric current through the specimen is measured, and the emitted charged particles are analyzed versus their energy (using a contactless voltmeter) which provides local potential values at chemical entities of the specimen.Type: GrantFiled: November 15, 2004Date of Patent: December 12, 2006Assignee: Yeda Research and Development Company Ltd.Inventors: Hagai Cohen, Igor Lubomirsky

Patent number: 6597051Abstract: A thermoelectric infrared detector comprising a substrate and two kinds of conducting pillars. The pillars longitudinally extend away from the substrate towards incident infrared radiation. The pillars have upper, hot ends remote from the substrate and lower ends at the substrate. Pairs of adjacent pillars of different kinds are electrically connected by a conducting junction at their upper ends, and thereby define thermocouples. The junctions of different pairs of pillars are exposed to the incident radiation.Type: GrantFiled: May 22, 2001Date of Patent: July 22, 2003Assignee: Yeda Research and Development Co.
