This technology is beyond current state-of-the-art approaches in manufacturing large-scale IPMC devices, and provides a universal solution to construct micro-size- featured IPMC transducers with fine contours and no short-circuits. To demonstrate the usefulness of the method, hand-shaped grips for laparoscopic operation are designed, fabricated and tested. The fabricated device with the dimension of 6 mm times 6 mm times 80 mum shows that it could reach a displacement of 300 mum at the location 1 mm away from the anchor when a 0.5 Hz square wave of 12 Volts is applied, and a maximum instantaneous force of 5 mN output when it is driven with a 0.5 Hz square wave of 6 Volts.","PeriodicalId":6388,"journal":{"name":"2007 IEEE 20th International Conference on Micro Electro Mechanical Systems (MEMS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85141671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fabricated devices generate up to 20.68plusmn0.32 muWcm-2K-2 for the case of vanishing thermal interface resistance (K=0). The generator keeps functionality when bent to curvatures with radii down to 7.5 mm. This allows for enhanced thermal contact to non planar surfaces. A specific electrical contact resistance between thermoelectric material and interconnects of 2.11*10-11 Omega m2 have been achieved in average, which is crucial for low generator resistance and hence for improved performance. First model based design optimization predictions are experimentally verified.","PeriodicalId":6388,"journal":{"name":"2007 IEEE 20th International Conference on Micro Electro Mechanical Systems (MEMS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85266489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is demonstrated that the irradiation of weak laser can enhance the response of the transducer due to the nonlinear photothermal effect.

It is well known that microelectrodes show higher sensitivity and higher S/N ratio. Downsizing of electrode, however, causes a reduction in signal current. Co-author has proposed a novel theoretical concept of a stripe electrode to solve this trade-off. The S/N ratio increases with downsizing the width of the stripe electrode because the noise current exponentially decreases. The nano stripe electrode with 450 nm in width and 15 mum in the center-to-center separation of the electrode could achieve 17.15 times higher S/N ratio than that of a planar electrode having the same corresponding area size. Furthermore, comparisons of experimental and theoretical S/N ratios will be discussed.","PeriodicalId":6388,"journal":{"name":"2007 IEEE 20th International Conference on Micro Electro Mechanical Systems (MEMS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82059518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main idea of the vertical probe design was how to distribute the total forces vertically concentrated on the probe tip in measuring semiconductor devices. To solve the problem, we designed the vertical probe tip with meander structure which could provide enough displacements so that the vertical probe tips could distribute the forces acting on the tips. The structural analyses of the probe tip were accomplished using finite element method (FEM) and compared with actual measurement values. The primary fabrication processes were surface micromachining, wafer bonding technology, and electroplating. The material of the electro-plated probe tip was an Ni-Co alloy. In this study, we demonstrated the potential of the vertical probe tip that could apply to a small area with the over drive (O.D.) of 10~40 mum and the contact force of 1~8 gf. The measured contact resistance was less than 2 Omega and little noise was observed.","PeriodicalId":6388,"journal":{"name":"2007 IEEE 20th International Conference on Micro Electro Mechanical Systems (MEMS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81432547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Up to 600 beads per second and channel are issued from the micronozzle through an air gap towards a standard lab tube (\"Eppi\") attached to the rotor spinning and containing a curing agent. At spinning frequencies between 5 Hz and 28 Hz, the tubes align horizontally under rotation and return to a vertical position as soon as the rotor is at rest.

The implanted receiver is a piezoelectric acoustic transducer and is packaged by biocompatible cohesive gels. This specific package is soft enough to absorb the incident wave from the subcutaneous tissue. The receiver employs direct charging to convert the acoustic energy into the extractable electrical energy through piezoelectricity when exposed to the acoustic field. The effects of the scattering package shape and the stiffness ratio between the package and subcutaneous tissue are considered to design the receivers. The energy efficiency of the fabricated receiver is measured inside real streaky pork, which is used to simulate human subcutaneous tissue. The result indicates that the spherical package is more suitable than the cubic one when they are buried in the fatty layer.
