The energy to be harvested comes from ambient vibrations as external energy sources. In particular, we consider two sources increasingly available in the ambient or in the human body and often both are mixed together: periodic induced waveforms and stochastic sources. The oscillator is composed of multiple magnetically-coupled bi-stable cantilevers with different natural frequencies inside each single well. The structure of the oscillator, modeling, simulations and measurement data will be here described. The principle has been validated and compared with other nonlinear techniques already proposed in literature. In particular the results show the possibility to efficiently recovery energy from mixed-sources having rich spectrum dictated by random vibrations and low frequency peaks consequence of periodic sources. The proposed device, based on piezoelectric output, is suitable to be used as converter in order to supply wireless sensor networks, autonomous nodes or it can be applied as power sustainer for communication of integrated devices and contactless measurement systems.","PeriodicalId":432388,"journal":{"name":"2013 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130166036","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 system allows to simultaneously characterize up to 8 sensors. Prototype sensors can be easily realized thanks to an ad hoc structure based on an alumina substrate equipped with electrodes, a heater and an accurate temperature sensor, on this structure the studied material can be deposited by screen printing, spin coating or dip coating. The system is designed to study the behavior of the sensors by accurately setting the operating conditions in terms of chemical environment composition, gas flow, humidity and temperature. The system is fully programmable and it individually controls the film temperatures or measures them with a resolution lower than 0.1 °C. Both chemical transients and thermal transients can be studied. These features make the system suitable for determining the principal performance indexes of a gas sensing device (e.g., sensitivity, stability, selectivity, response/recovery times, etc.) as functions of various combinations of measurement conditions (e.g., gas concentrations, temperature, humidity, flow). The proposed measurement system will find also useful applications in sensor model validation.","PeriodicalId":432388,"journal":{"name":"2013 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130989010","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 chicken meat was stored in a refrigerator for 13 days at 4 oC. The changes in dielectric constant and loss factor reflected changes related to water binding, water loss and ionic activity. The dielectric constant decreased with frequency and storage duration with a slope change at about 4 GHz. The frequency dependence of the dielectric loss factor was dominated by the ionic conduction in the lower frequency range and dipolar relaxation of water above 4 GHz. The dielectric loss factor increased with storage duration for frequencies below 4 GHz and remained almost constant above that. For purpose of comparison, the effect of water loss by mechanical extraction on dielectric properties of chicken meat was investigated. The frequency dependence was found to be similar to that observed for the aging with both the dielectric constant and dielectric loss factor decreasing with the water loss at all frequencies. This will be developed further to better understand the dynamic of aging and its effect on the quality of chicken meat.","PeriodicalId":432388,"journal":{"name":"2013 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131694882","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}
