This paper presents a self-folding method for multi-crease structures. The proposed method utilizes the symmetric breaking of a 3-layered two-dimensional sheet, where an inner contraction sheet induces shear force when heated, which directs the inclined folding direction. The fabrication technique developed enables distant placements of tiling patterns of the surfaces. The experimental result s...

A technique for electron multiplication in gas is being developed that lends itself to easy fabrication with lithographic techniques. Moreover, the electrical characteristics of the resulting device are very stable. Comprising an array of anode pins that are recessed into a closely-packed hexagonal cathode, the MIcro-Pin Array (MIPA) represents a promising addition to micro-pattern detectors wi...

As new synthetic, low-loss polymers are developed, polymer optical cavities are experiencing a revolution, in both fabrication design and functionality. Recently, a fabrication technique was developed that enabled planar arrays of polymeric resonators to achieve cavity Q factors greater than 1 million. In the present letter, this molding technique is expanded to fabricate resonators from polyme...

We describe the nanofabrication study of self-aligned electrodes on suspended multiwalled carbon nanotube structures. When metal is deposited on a suspended multiwalled carbon nanotube structure, the nanotube acts as an evaporation mask, resulting in the formation of discontinuous electrodes. The metal deposits on the nanotubes are removed with lift-off. Using Al sacrificial layers, it was poss...

A miniature Clark-type oxygen sensor has been integrated with a microstructure using a novel fabrication technique. The oxygen chip consists of a glass substrate with a three-electrode configuration, which is separated and connected by a groove, and a poly(dimethylsiloxane) (PDMS) container with an immobilized PDMS oxygen-permeable membrane. The assembly of the different substrates only uses th...

This paper proposes a novel technique to measure fabrication artifacts through direct comparison of a reference surface model with the corresponding industrial CT volume. Our technique uses the information from the surface model to locate corresponding points in the CT dataset. We then compute various comparison metrics to measure differences (fabrication artifacts) between the two datasets. Th...

This paper describes, from the viewpoint of device fabrication, single-electron and quantum devices using silicon-oninsulators (SOIs). We point out that control of the oxidation of Si is quite important and could be the key to their fabrication. We also introduce our technique for making single-electron transistors (SETs), which uses special phenomena that occur during the oxidation of SOIs, an...

A laser direct-writing technique employing multiphoton absorption processes has become a powerful and widely used tool in the fabrication of micro-/nanometer-scale structures in the past decade because of its 3D fabrication ability. Using this technique, a number of 2D and 3D microstructures have been successfully created with polymers, glasses, and metals. In particular, since nanoscale metals...

I present a brief review of a cellular separation technique known as dielectrophoretic field-flowfractionation. The technique relies upon suspending different cells at different heights within a laminar flow profile. The differentially suspended cells, thus, travel at different speeds and elute from the flow chamber at different times resulting in successful separation. An alternate fabrication...

This thesis reports an automatic method for synthesizing MEMS mask-layouts. This method incorporates a forward simulation of fabrication into a general evolutionary algorithm loop. An initial random population of mask-layouts is generated. The fabrication of each layout is simulated through a digital process simulator to produce a 3D fabricated shape, which is compared to a user-specified desir...
