As a result, we could obtain adequate flow rate ratios of sample and sheath flow, which is in the vicinity of 1:5 for our device. A bacteria enumeration experiment has also been carried out, based on the simulation results, and we have achieved hydrodynamic focusing at the expected position and proper sample flow rate.","PeriodicalId":20476,"journal":{"name":"Proceedings of IEEE Sensors, 2004.","volume":"590 1","pages":"308-311 vol.1"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73326164","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}

PZT screen-printed elements, behaving as thickness-mode resonators provide energy to SOI-based micro-resonators. A significant degree of innovation lies in the miniaturization of the system, in the relevant decreasing of operating frequency, in the novel optical sensing strategy based on metal-dielectric (MD) photonic band gap (PBG) structures, and in selective thermal-deposition of polymer which has been predisposed. A signal conditioning architecture based on a closed loop configuration is considered to measure the variation of frequency as a function of the micro-mechanical proof-mass variation. A high benefit is obtained in tracking the resonance condition variations, due to the very high quality factor, which has been experimentally measured. A theoretical sensitivity of 580 (Hz//spl mu/g) have been evaluated for test devices having resonance frequencies less than 10 kHz.","PeriodicalId":20476,"journal":{"name":"Proceedings of IEEE Sensors, 2004.","volume":"4 1","pages":"264-267 vol.1"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73370114","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}

Simulation and experimental results on a surface micromachined test structure are used to identify deflection versus voltage characteristics. These characteristics are scaled based on typical gyroscope parameters and the findings are that levitation forces can cause more than 50% reduction in scale factor and more than 0.1% increase in undesirable cross-axis sensitivity.","PeriodicalId":20476,"journal":{"name":"Proceedings of IEEE Sensors, 2004.","volume":"79 1","pages":"508-511 vol.1"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78971459","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 device is CMOS compatible and consists of a polysilicon heater and two thermopiles, situated symmetrically on each side of a heater. A thick porous silicon (PS) layer assures thermal isolation from the Si substrate. The operating principle is based on the movement induced thermal convection variations between the heater and the hot thermopile contacts, which is caused by the movement of the hot air on top of the heater relative to the sensor die. The porous silicon thermal accelerometer (PSTA) was tested in a specially designed vibration system for different frequencies and accelerations. In each case, the response was compared to a commercial accelerometer. Appropriate read out electronics were fabricated in order to reduce the noise of the thermopiles and to amplify the signal. The dependence of the response on applied power and the surrounding environment was also studied.","PeriodicalId":20476,"journal":{"name":"Proceedings of IEEE Sensors, 2004.","volume":"359 1","pages":"848-851 vol.2"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76379199","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 present authors have developed a system in which a magnetic sensor and an optical sensing system are used to measure the thickness of various sheets.

In the present study, a new system for inspecting the sheet thickness is realized which results in accurate measurements. With the use of a calibration gauge, it was found that the thickness measuring system drastically improved the inspection of sheet thickness without use of a standard sheet, resulting in a precision of /spl plusmn/0.5% or less for a composited sheet thickness of 730 /spl mu/m during the manufacturing process.","PeriodicalId":20476,"journal":{"name":"Proceedings of IEEE Sensors, 2004.","volume":"6 1","pages":"320-323 vol.1"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76421681","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}

Although a number of applications have been proposed to show that IPMCs can work both as actuator or as sensor, none has been produced that exploits both properties in one application. The developed system is composed of a sensor that monitors the vibrations of a membrane under the effects of external disturbances. The sensor output is manipulated and sent to the actuator to reduce vibrations of the membrane itself.

The temperature of the fish is monitored by the loggers, which contain a thermistor and RF transmitter circuitry. The data is sent at fixed intervals (usually 5 minutes) to the base station. Through a GSM modem, the base station communicates the collected data to the shore where a server uploads the temperature-time information to a database. The database and controlling software are completely Web-based and can be accessed by an Internet-enabled PC, laptop or PDA. This allows remote initiation and control of the system, in addition to querying of the database.

Our device makes use of dew-point temperature detection approach, to achieve simple operation and high reproducibility. It is based on a suspended plate, anchored to the substrate by means of four arms. The thermoelectric Peltier effect is exploited to cool the plate until an interdigitated capacitor on top of the plate detects moisture and triggers the temperature measurements by means of thermocouples. By measuring dew-point and ambient temperatures, RH can be calculated through psycrometric charts.
