Morphology and composition of the cathodes were investigated by SEM and EDX analysis. The observations revealed the RuO 2-Ni layers covered by cauliflower-like particles which distributed homogeneously on the Ni substrate. Particle size and distribution of RuO2 particles in suspension and on the cathode surface were studied by light scattering (LS) and X-ray map techniques, respectively. The LS results revealed a Gaussian distribution with an average RuO2 particle size of 527nm in suspension while X-ray map showed a non-uniform nano particle size distribution below 100 nm. Electrochemical activity of the cathodes were evaluated by linear sweep voltametry (LSV) and the results showed that the enhanced activity of the cathodes were mainly ascribable to the RuO 2 content or the increase in the active sites. The effect of Ni substrates pre-treatment on activity and morphology of prepared cathodes showed morphology changes and enhanced effect on electrochemical activity of the cathodes","PeriodicalId":6362,"journal":{"name":"2006 1st IEEE International Conference on Nano/Micro Engineered and Molecular Systems","volume":"43 1","pages":"1258-1262"},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80246204","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 altering the frequency of the applied voltage and the surrounding medium of a EWOD device, we found that when using oil as surrounding medium and applying an AC signal 100 kHz, liquid column would be drawn and follow the thin connecting lines of the EWOD driving electrodes instead of remaining on top of the center of the EWOD driving electrodes. This new phenomenon is described in this paper and is regarded as a LDEP effect. Three fundamental tools for integrated digital and analog microfluidics are developed, including a digital-to-analog converter, an analog-to-digital converter, and a valve. Combining EWOD and LDEP effects, liquids can be pumped on a virtual channel (analog microfluidics), defined by energized thin LDEP electrode lines, continuously from liquid reservoir or from a digitized droplet (digital microfluidics). On the contrary, liquids on LDEP electrodes (analog microfluidics) can also be pumped on a EWOD electrode and be digitized in droplet forms with precise volumes (digital microfluidics). EWOD and LDEP can be selectively programmed on a single chip, making integrated digital and analog microfluidics a reality","PeriodicalId":6362,"journal":{"name":"2006 1st IEEE International Conference on Nano/Micro Engineered and Molecular Systems","volume":"54 1","pages":"1414-1417"},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80796858","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}

In this paper, a flexible fabric strain sensor with high sensitivity, good stability and large deformation is reported. It is fabricated by depositing a nano-layer (200nm to 300nm) of polypyrrole on the fabric substrate at low temperature. Thickness and morphology of the conducting thin film on the surface of the fibers were examined by scanning probe microscopy (SPM) and scanning electron microscopy (SEM). The measurement of the conductivity change with strain shows the fabrics so prepared exhibits a high strain sensitivity of ~160 for a deformation as large as 50%, while its good stability is indicated by a small loss of conductivity after the thermal and humidity aging tests, and supported by the slight change in conductivity and sensitivity over a storage of eighteen months. The flexible strain sensor is expected to be a promising \"soft\" smart material with good sensing properties in the preparation of smart garment, wearable hardware and biomedical applications","PeriodicalId":6362,"journal":{"name":"2006 1st IEEE International Conference on Nano/Micro Engineered and Molecular Systems","volume":"23 1","pages":"1245-1249"},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77775774","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}
