As a simple case, we first investigate the behaviors of a single-layered plate which is traction free and applied thermal shock. After that a double-layered plate with imperfect interface is studied, and the same boundary conditions are adopted on its external surfaces as used on the single-layered plate. The Laplace transform and the Riemann-sum approximation method are utilized to solve the coupled piezoelectric-thermo-elastic governing equations of the dynamic problems. The semi-analytical solutions are obtained. Results obtained reveal that the imperfect interface leads to the reduced speed of thermo-elastic wave, the weak attenuation of temperature and the enlarged amplitude of displacement. Furthermore, a temperature drop at the front of the thermal wave is also newly found.","PeriodicalId":412736,"journal":{"name":"Proceedings of the 2014 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129652288","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 Love wave device consists of two interdigital transducers (IDTs) with a period of 28 μm, an ST-90 X quartz substrate. Three different films of SU-8, SU-8+PVA and PVA, were spin-coated on the substrate surface by a sol-gel process as the waveguide layer and the sensing film. A detailed description was presented for the preparation of the solution and coating and curing process of SU-8 and PVA. A network analyzer was used to measure the operation frequency and insertion loss of the sensor at different relative humidity. The absorption mechanism of polymeric layers was analyzed and the mechanism was successfully used to explain the experimental results of the humidity sensing of Love wave devices coated with SU-8, SU-8+PVA, or PVA layers.","PeriodicalId":412736,"journal":{"name":"Proceedings of the 2014 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131777864","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 report, a novel strategy of collecting coarse and fine droplets from the air, which employs an ultrasonic field in the air gap between a flat radiation surface and parallel reflector, is demonstrated. Coarse and fine droplets (PM2.5-10 and PM2.5) can be effectively collected onto the reflector's surface when the air gap thickness is proper. The radiation surface works in a flexural vibration mode at 56.9 kHz, and the collected droplets may form concentric rings and irregular shape on the reflector's surface. Analyses show that both of the acoustic streaming and acoustic radiation force are responsible for the collection.","PeriodicalId":412736,"journal":{"name":"Proceedings of the 2014 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134433515","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 test results showed that the static force had different effect on hard and soft ceramics materials, and the frequency and the amplitude of driving force made significant impact.

The initial cervical screening of cervical lesion is very important. In this study, a novel method for early cervical cancer detection based on piezoelectric immunosensor was proposed. The method proposed in this paper involved short analyzing time for p16INK4a detection, a protein that has been linked to cervical cancer. p16INK4a antibody was dripped on the center of the AT-cut crystal and supernatant from different clinical sample was also dripped on the center of crystal, Absorb of the p16INK4a by antibody caused a shift in the resonant frequency of the immunosensor and the resonant frequency was correlated to the amount of the p16INK4a in supernatant. This method can be a promising assay for the initial screening of cervical lesion.","PeriodicalId":412736,"journal":{"name":"Proceedings of the 2014 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115482786","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}
