We present a numerical analysis of band structure and phononic band gaps of different cubic unit cell geometries. For validation, we report experimental results for transmission of acoustic waves in different characteristic spatial directions through various phononic crystal samples. These results are supplemented by numerical transmission analysis. The elements form the building blocks of wideband, high-resolution phononic-fluidic systems for measuring physical properties such as fluid density, speed of sound, and concentration.","PeriodicalId":174774,"journal":{"name":"2017 19th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114075315","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 all-transparent microfluidic chip consists of a constriction channel and an array of embedded indium-tin-oxide (ITO) electrodes through which cell position can be tracked with high resolution. Therefore, information regarding cell transit times and velocities during cell deformation can be readily assessed without the use of video microscopy. The deformability chip is also unique in that it separates the delivery and sensing channel thereby preventing cell clogging. The performance of the chip has been verified by single-cell analysis of breast cancer cells.","PeriodicalId":174774,"journal":{"name":"2017 19th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS)","volume":"12 12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129782318","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}

By optimizing geometry and fabrication process of an ultra-thin (400 nm) metal-insulator-metal (MIM) metamaterial structure, we have been able to experimentally demonstrate high absorptivity (η>91%) mid-IR absorbers with the narrowest absorption bandwidth reported to date (full width at half maximum, FWHM∼225 nm, 4.29% at λ=5.23μm), while maintaining angle (θ=0∼60°) and polarization insensitivity. The unprecedented performance of such batch-microfabricated and lithographically defined ultra-thin absorbers paves the way to the development of new classes of plasmonically-enhanced multi-spectral sensing and imaging microsystems for non-invasive chemical sensing and IR spectral signature detection.","PeriodicalId":174774,"journal":{"name":"2017 19th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116029342","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 sensors and the platforms that carry them must operate from the surface to depths of several kilometers.

Much of the focus will be on chemical sensors that can operate for years at a time without laboratory recalibration.","PeriodicalId":174774,"journal":{"name":"2017 19th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126513690","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}

A simple microfluidic chip, composed of a straight microchannel and a pair of coplanar electrodes was designed to form a microfluidic impedance cytometry. The electrodes were used to perform the impedance measurement of C. elegans nematodes when worms were flowing through the channel. Electrical signals and concurrent videos were recorded and analyzed to investigate the relationship between the impedance amplitude and the worm length. The result demonstrated that the length of nematodes is linearly correlated to the cubic root of EIS signal amplitude. Therefore, the life stages of C. elegans can be identified through this microfluidic impedance cytometry.","PeriodicalId":174774,"journal":{"name":"2017 19th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128851713","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 internally integrated passive silicon structure, with increasing amplitudes of shock, realizes nonlinear growth in shock resistance and reveals positive selectivity and compatibility, through three energy dissipation modes. This approach enables a generic batch fabrication requiring no additional processes or excessive area expansion (290μm×320μm for an 8cm×8cm device in this work). The SANS has been verified to provide enhanced shock robustness over conventional shock protective structures, namely the hard stop (∼2 times) and the flexible spring stop (∼1.5 times).","PeriodicalId":174774,"journal":{"name":"2017 19th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117164340","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 sensor consists of a piezoresistive cantilever and a chamber covered with a superoleophobic membrane. The vibration of a droplet on the membrane causes the pressure of the chamber to change. Since the cantilever is able to detect a pressure change of less than 0.1 Pa, the vibration of the droplet can be precisely measured by the cantilever. In comparison to previously developed MEMS-based force sensor to measure the droplet vibration, the current sensor design offers several benefits including: wide range of usable liquids, simple sensing scheme (only one sensor is required) and capability to be disposable. With these advantages, our method is believed to be useful in measuring viscosity of small droplet for point-of-care application.","PeriodicalId":174774,"journal":{"name":"2017 19th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114219303","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}
