We have previously reported the ion channel recordings with bilayer lipid membranes (BLMs) which formed on a parylene micropore using droplets contact method. However, the low reconstitution probability of ion channels into BLMs has been a major issue. In this study, BLMs area and position are regulated with changing the numbers and positions of the parylene micropores. As a result, the simultaneous single channel recordings of K+ channel expressed in nerve system with BLM array were able to be achieved at the high probability.","PeriodicalId":92162,"journal":{"name":"2013 IEEE 26th International Conference on Micro Electro Mechanical Systems (MEMS 2013) : Taipei, Taiwan, 20-24 January 2013.

The inertial effect of rarefied gas fluid is detected as a variation of the resonance frequency, and the dissipation of the interaction energy between the resonator and the gas molecules affects the damping of oscillation. Thus, two kinds of gaseous species can be distinguished with one device. The MWCNTs have been arranged on the resonator for heightening its sensitivity by the bio-MEMS compatible process. The MWCNTs embedded-resonator has successfully demonstrated to detect and distinguish hydrogen and nitrogen gases under pressures of 0.02 Pa to 0.9 Pa.","PeriodicalId":92162,"journal":{"name":"2013 IEEE 26th International Conference on Micro Electro Mechanical Systems (MEMS 2013) : Taipei, Taiwan, 20-24 January 2013.

However, magnesium microfabrication has been limited to sub-micron-thick film technologies (i.e., sputtering or evaporation). This paper presents three magnesium microfabrication approaches for thicknesses greater than 10 μm: 1) laser-cutting and 2) chemical etching of 70-μm-thick commercial magnesium foil; and 3) through-mold electroplating of magnesium from non-aqueous solution. The fabrication technologies are compared on minimum feature size, morphology, uniformity, composition and electrical resistivity. Preliminary results confirmed that the 50-μm-thick electroplated material composition compared favorably with commercial magnesium foil. The measured electrical resistivities of commercial and electrodeposited magnesium were 5.3 μΩ·cm and 8.7 μΩ·cm, respectively. Thick magnesium microstructures can be fabricated through several means to serve a broad range of MEMS-based applications.","PeriodicalId":92162,"journal":{"name":"2013 IEEE 26th International Conference on Micro Electro Mechanical Systems (MEMS 2013) : Taipei, Taiwan, 20-24 January 2013.

This device has the potential to meet the demand for flexible and cost-effective tools that can perform high throughput genetic screening for applications such as allelic variation detection in agriculture. The microfluidic droplet-based device accepts an unlimited number of sample plugs containing genomic plant DNA from a multi-well plate. Each plug is separated by a fluorinated immiscible carrier fluid to prevent cross-contamination. Once plugs are loaded on to the device, mechanical chopping of these sample plugs is performed to digitize them into smaller daughter droplets. The device then performs subsequent synchronization-free, robust injection of multiple single nucleotide polymorphism interrogating probes in to the sample daughter droplets on-demand. This microfluidic platform combines the excellent control of valve-based microfluidics with the high-throughput capability of droplet microfluidics. Furthermore, generation of a one-dimensional array of combinatorial mixtures of DNA-probe droplets in which the sequence of drops is maintained throughout the device leads to automatic spatial indexing of these droplets, precluding the need for barcoding to identify droplet contents. We expect this flexible platform to expand the range of applications of droplet microfluidics to include applications requiring high degrees of multiplexing as well as high throughput screening of arrays of samples.","PeriodicalId":92162,"journal":{"name":"2013 IEEE 26th International Conference on Micro Electro Mechanical Systems (MEMS 2013) : Taipei, Taiwan, 20-24 January 2013.

After transferred, the device is temporary sealed with a silicone ring, and underfill polymer can be used for permanent bonding. Because silicone bonding is made just by physical contact at room temperature, and the elasticity of silicone absorbs mismatch in thermal expansion, integration between different materials of wafer is possible. For practical demonstration, LiNbO3-based SAW resonators were transferred to an LSI wafer.","PeriodicalId":92162,"journal":{"name":"2013 IEEE 26th International Conference on Micro Electro Mechanical Systems (MEMS 2013) : Taipei, Taiwan, 20-24 January 2013.

The key feature of this process is the use of a blow torch that can provide intensive localized heat up to 2500°C in a very short time (<;10 sec), above the melting temperatures of many high-Q materials such as fused silica. Surface roughness of 5.3 Å is realized in fused silica, which is crucial for high optical and mechanical quality factors (Q). We demonstrate the fabrication of micro hemisphere and half-toroid (birdbath) geometries from 100μm-thick fused silica substrates. We also create micro birdbath resonators by batch-level releasing the birdbath shells and demonstrate one of the best mechanical Q and low stiffness and damping anisotropies among existing micro mechanical resonators. The birdbath resonator is promising for emerging applications such as micro rate-integrating gyroscope (μ-RIG).","PeriodicalId":92162,"journal":{"name":"2013 IEEE 26th International Conference on Micro Electro Mechanical Systems (MEMS 2013) : Taipei, Taiwan, 20-24 January 2013.
