摘要： An acoustic sensor and method of using same for determining the position of a tool from a workpiece are disclosed in which a piezoelectric transducer having a curved surface emits a sound wave which strikes the workpiece and is reflected back to the sensor. The sensor and tool are positioned relative to one another so that the workpiece will be near the focal point of the curved surface when the tool is operating. This positioning substantially overcomes the attenuation problems of high frequency sound waves transmitted through air.

摘要： The current invention provides a fabrication method for large surface area, pinhole-free, ultra thin ion conducting membranes using atomic layer deposition on inexpensive sacrificial substrates to make cost effective, high performance fuel cells or electrolyzers. The resultant membrane electrode assembly (MEA) enables significant reduction in resistive losses as well as lowering of the operating temperature of the fuel cell. The invention further provides a method to deposit 3-dimensional surface conformal films that may have compositional grading for superior performance. In addition, the invention provides decoration and modification of electrode surfaces for enhanced catalytic activity and reduced polarization losses. The method of the current invention enables the MEA structure to be fabricated from the anode side up or the cathode side up, each with or without an incorporated anode current collector or cathode current collector, respectively.

摘要： Area selective atomic layer deposition is provided by a method including the following steps. First, a substrate is provided. Second, a tip of a scanning probe microscope (SPM) is disposed in proximity to the surface of the substrate. An electrical potential is then established between the tip and the surface that cause one or more localized electrical effects in proximity to the tip. Deposition reactants for atomic layer deposition (ALD) are provided, and deposition occurs in a pattern defined by the localized electrical effects because of locally enhanced ALD reaction rates.

摘要： This invention provides small position sensors for applications where localized sensing in a small volume of space is needed but where measurement of large relative displacement is also necessary. The invention enables a surgeon to accurately position the tip of a catheter during minimally invasive therapy. The current invention further improves the quality of tactile feedback to a physician during catheter-based surgeries with an axial force sensor at the tip of the catheter that allows for the transmission of force information to the physician. One embodiment of this invention is a position sensor for active interventional catheters, where the sensor may be laser-machined shape memory alloy (SMA), and the catheter actuators may be heated SMA or wire-pulleys. Providing position feedback from a catheter during minimally invasive therapy allows for closed-loop control of the catheter tip position under computer-aided guidance and enable force feedback to the physician.

摘要： A simple, inexpensive and highly efficient fuel cell has boundary structures made of a photo-sensitive material in combination with selective patterning. Printed circuit board (PCB) fabrication techniques combine boundary structures with two and three dimensional electrical flow path. Photo-sensitive material and PCB fabrication techniques are alternately or combined utilized for making micro-channel structures or micro stitch structures for substantially reducing dead zones of the diffusion layer while keeping fluid flow resistance to a minimum. The fuel cell assembly is free of mechanical clamping elements. Adhesives that may be conductively contaminated and/or fiber-reinforced provide mechanical and eventual electrical connections, and sealing within the assembly. Mechanically supporting backing layers are pre-fabricated with a natural bend defined in combination with the backing layers' elasticity to eliminate massive support plates and assist the adhesive bonding. Proton insulation between adjacent and electrically linked in-plane cell elements is provided by structural insulation within the central membrane.

摘要： Provided are a method of preparing a fuel cell and a membrane electrode assembly prepared by the method. The method includes preparing a substrate, forming a buffer layer having a single crystalline structure on the substrate, forming a proton conducting solid perovskite electrolyte membrane on the buffer layer, forming a first electrode on one surface of the proton conducting solid perovskite electrolyte membrane, etching the substrate, and forming a second electrode on the opposite surface of the one surface of the electrolyte membrane. Thus, the method of preparing a fuel cell can improve ion conductivity of an electrolyte membrane at a low temperature and a membrane electrode assembly of a fuel cell prepared by the method can improve ion conductivity at a low temperature.

摘要： Efficient photovoltaic devices with quantum dots are provided. Quantum dots have numerous desirable properties that can be used in solar cells, including an easily selected bandgap and Fermi level. In particular, the size and composition of a quantum dot can determine its bandgap and Fermi level. By precise deposition of quantum dots in the active layer of a solar cell, bandgap gradients can be present for efficient sunlight absorption, exciton dissociation, and charge transport. Mismatching Fermi levels are also present between adjacent quantum dots, allowing for built-in electric fields to form and aid in charge transport and the prevention of exciton recombination.
