A corresponding external servo-loop array is built for separate control of probe scanning. A macro-goniometer is introduced for probe chip-sample alignment. Using the dual-probe array system, two STM images on a gold calibration sample are obtained simultaneously, and TiO2 nanowires are written on a Ti surface.","PeriodicalId":92162,"journal":{"name":"2013 IEEE 26th International Conference on Micro Electro Mechanical Systems (MEMS 2013) : Taipei, Taiwan, 20-24 January 2013.

We can expect 3D curing properties through characteristics of resin and microparticles. Therefore, our theory is useful for developing newly photocurable polymer not only with microparticles, but also without microparticles. We believe that our model becomes fundamental theory for the 2D and 3D microfabrication in the photolithography and microstereolithography.","PeriodicalId":92162,"journal":{"name":"2013 IEEE 26th International Conference on Micro Electro Mechanical Systems (MEMS 2013) : Taipei, Taiwan, 20-24 January 2013.

First, for the three-dimensional (3D) propulsion of the microrobot in arbitrary shaped blood vessels, an electromagnetic system consisting of the horizontal and vertical pairs of Helmholtz and Maxwell electric coils is designed and manufactured along with the verification of the magnetic flux density generated from the designed system with theory. Using the developed electromagnetic system, the propulsion of a spherical microrobot (800 μm dia.) made of a cylindrical magnet covered with clay is successfully demonstrated in x-y and x-z plains along with a T-shaped glass channel. Second, an acoustically oscillating bubble induced microstreaming is separately investigated by using a high speed camera integrated with a zoom lens and laser as a light source. When a bubble is acoustically excited by a piezoactuator around its natural frequency, it oscillates and simultaneously generates microstreaming and radiation forces, which can be used to manipulate (pull and push) neighboring objects. Finally, as the concept proof, the manipulation of a fish egg (800 μm dia.) in a microfabricated channel with tandem rectangular hills is experimentally achieved by the microrobot incorporated with an acoustically oscillating bubble.","PeriodicalId":92162,"journal":{"name":"2013 IEEE 26th International Conference on Micro Electro Mechanical Systems (MEMS 2013) : Taipei, Taiwan, 20-24 January 2013.

The array device is fabricated by bonding a PDMS microchannel layer and a glass wafer. Discharge electrodes for plasma creation are fabricated by Au/Cr layers. Since the discharge starting voltages strongly depends on shapes and the gap of two electrodes, they were designed and selected based on the Paschen's law to lower their discharge starting voltages.

Previously, a wide range of self-regulating microfluidic components, such as fluidic diodes, have been developed; however, achieving effective functionality at ultra-low Reynolds number (e.g., Re <; 0.05) has remained a significant challenge. To overcome this issue, here we introduce single-layer microfluidic “domino” diodes, which utilize free-standing rotational microstructures - constructed in situ via optofluidic lithography - in order to passively regulate the fluidic resistance based on the flow polarity, thereby enabling flow rectification under ultra-low Re conditions. COMSOL simulation results revealed a theoretical Diodicity (Di) of 31 for a singular domino diode component. Experimental results (for systems with four microstructures) revealed Di's ranging from 13.0±1.9 to 25.4±1.9 corresponding to 0.025 <; Re <; 0.030 and 0.010 <; Re <; 0.015 flow, respectively, which represent the largest Di's reported for Re <; 0.05 fluid flow.","PeriodicalId":92162,"journal":{"name":"2013 IEEE 26th International Conference on Micro Electro Mechanical Systems (MEMS 2013) : Taipei, Taiwan, 20-24 January 2013.
