Publication number: 20220221949Abstract: The present invention provides a touch sensor and a method for preparing the same. The touch sensor includes a substrate, an electrode layer located in a window area, and a frame trace located in a frame trace area. The frame trace includes a plurality of metal wires. Each metal wire includes a metal wire body electrically connected to a corresponding electrode in the electrode layer and an insulation layer wrapped around an outer periphery of the metal wire body. In this way, the width of the frame trace area can be further reduced.Type: ApplicationFiled: November 22, 2019Publication date: July 14, 2022Inventors: BIAO DENG, JIE MA, BEI LEI, KAI JIANG, HAK FEI POON

Patent number: 9053938Abstract: Methods and devices are provided for forming a low-resistance, high light transmission layer. In one embodiment of the present invention, a method is provided comprised of creating a plurality of vias on a substrate, the vias formed in material that has a maximum processing temperature that less than a pre-defined threshold; adding a plurality of electrically conductive material into the vias; and solution depositing a nanowires infused window layer that has a first thickness at certain areas and a second thickness at other areas, wherein overall sheet resistance is between about 1 to 10 ohms per square, while light transmission combined is at least 70% and creates less than 5% shadow loss. The method may involve using a transparent conductive oxide layer beneath the window layer. This can create a layer that eliminates opaque bus bars or fingers associated with traditional solar cells. This may be an all-solution deposited process using only one deposition set or multiple deposition steps.Type: GrantFiled: October 8, 2010Date of Patent: June 9, 2015Assignee: aeris CAPITAL Sustainable IP Ltd.Inventors: Hak Fei Poon, Tianyue Yu

Patent number: 8906285Abstract: An stable electrohydrodynamic filament is obtained by causing a straight electrohydrodynamic filament formed from a liquid to emerge from a Taylor cone, the filament having a diameter of from 10 nm to 100 ?m. Such filaments are useful in electrohydrodynamic printing and manufacturing techniques and their application in liquid drop/particle and fiber production, colloidal deployment and assembly, and composite materials processing.Type: GrantFiled: October 31, 2006Date of Patent: December 9, 2014Assignee: The Trustees of Princeton UniversityInventors: Ilhan A. Aksay, Hak Fei Poon, Sibel Korkut, Chuan-hua Chen, Joy Wagner Saville

Publication number: 20120237816Abstract: A bipolar battery may include a substrate having a matrix made of a thermoset polymer formed from a liquid precursor. One or more conductive pellets can be disposed in the matrix to provide electrical connection between opposite sides of the matrix. Each conductive pellet has a characteristic thickness that is greater than a thickness of the matrix. Each of the one or more conductive pellets protrudes beyond first and second surfaces of the matrix.Type: ApplicationFiled: March 15, 2011Publication date: September 20, 2012Applicant: YottaQ, Inc.Inventors: Martin R. Roscheisen, Brent J. Bollman, Hak Fei Poon, Zhengyu Wu, Boris Monahov, Sam Kao

Publication number: 20100197068Abstract: Methods and devices are provided for improved photovoltaic devices. In one embodiment, the transparent electrode of a thin-film solar cell is replaced in part by a sheet of nanowires. One technique for use in present invention comprises forming a solar cell having: a) a thinner than usual transparent top electrode of a conductive material having a reduced thickness and b) an interconnected network of nanowires in contact with and/or coated by the top electrode. In some embodiments, the top electrode and network of nanowires increases overall power output of the solar cell compared to an otherwise identical cell using only a) a top electrode layer of the material at a thickness and light transmission equal to a combined thickness and light transmission of the top electrode and the network of nanowires, or b) an interconnected network of nanowires of thickness equal to the combined thickness and light transmission.Type: ApplicationFiled: October 30, 2009Publication date: August 5, 2010Inventors: Hak Fei Poon, Tianyue Yu
