Piezoelectric ceramics are often used for sensory systems to monitor mechanical characteristics of structures through an electrical signal. Thus, to support system level analysis and evaluation of sensory systems, understanding and estimating the electrical behavior of piezoelectric ceramics with a minimum effort is valuable. This paper proposes an equivalent circuit model for piezoelectric ceramics, with a PZT patch as the specimen. The proposed model approximates the electrical behavior of piezoelectric ceramics with up to 100% accuracy for unloaded and 93% accuracy for loaded PZT, and provides a modeling procedure that can easily be automated.","PeriodicalId":225041,"journal":{"name":"2008 IEEE Sensors Applications Symposium","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122101118","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 proposed sensor showed high sensitivity and selectivity to acetic acid at optimal temperature of 293degC. Quantitative analysis was performed at a wavelength of 440 nm. The linear range of CTL intensity versus concentration of acetic acid are 25 mL/m3 to 500 mL/m3 and 501 mL/m3 to 2500 mL/m3, with detection limit of 8 mL/m3. No or only very low levels of interference was observed while the coexistence of other gases passing through the sensor. Formic acid, ethanol, acetaldehyde, formaldehyde, benzene, toluene, and n-hexane caused interference at around 2.7%, 4.5%, 10.8%, 2.0%, 2.9%, 2.7% and 2.3%, respectively. Chloroform and ammonia vapors did not show any interference. The technique has been successfully applied to determine acetic acid in the artificial air samples.","PeriodicalId":225041,"journal":{"name":"2008 IEEE Sensors Applications Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132430873","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}

Reaction time for these conventional impact sensors are either far too slow or, in many cases, fail to function completely for high G applications. In this study, a MEMS high G inertial impact sensor with a measurement range of 8,000-21,000 G is presented. The triggering mechanism is a combination of cantilever and spring structure. The design of the mechanism underwent a series of analyses. Simulation results indicated that a MEMS high G inertial impact sensor has a faster reaction time than conventional G inertial impact sensors that use a cantilever beam or spring mechanism. Furthermore, the MEMS high G inertial impact sensor is sufficiently robust to survive the impact encountered in high G application where most conventional G inertial impact sensors fail.","PeriodicalId":225041,"journal":{"name":"2008 IEEE Sensors Applications Symposium","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128737496","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}
