The PEM revealed to be a valuable tool for the determination of the presence of herbicides in water through the measurement of its optical properties. Among the most striking features of the PEM is the long time stability of the embedded protein that allowed the use of the same specimen for several months without any loss in sensitivity or reproducibility of the determinations. Here further details on the PEM structure and properties will be presented together with a first attempt to overcome the major drawback of the proposed biosensor, i.e.: its poor sensitivity.","PeriodicalId":246540,"journal":{"name":"2009 3rd International Workshop on Advances in sensors and Interfaces","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116595262","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}

Many different physiological parameters can be monitored and collected continuously by wearable wireless sensors with high accuracy, low power consumption and limited cost. In this work we focus on WBSN for real-time biofeedback applications. In this domain the real-time nature of I/O data streams is of critical importance for providing an useful and efficient sensorial feedback for the user while system lifetime should be maximized. Thus, bandwidth, throughput and energy efficiency of the communication protocol must be carefully optimized. The research community is still divided on the choice of the protocol to use (proprietary, ZigBee, Bluetooth). In this article we investigate how ZigBee meets WBSN requirements showing a higher communication efficiency and lower power consumption, with respect to Bluetooth Serial Port Profile, (SPP) based solution.","PeriodicalId":246540,"journal":{"name":"2009 3rd International Workshop on Advances in sensors and Interfaces","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128844639","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 current-mode approach exploited in the first stage of the proposed architecture allows to fulfill the severe constraints imposed by this kind of detectors in terms of dynamic range and speed of operation, without excessive power consumption. Timing accuracy of about 50ps, obtained with the electronics coupled to a fast pulse generator in series to a charge injection capacitance, has been obtained by means of a fast current discriminator. The circuit is specially intended for medical imaging applications, for instance PET, but programmability of detector bias, gain and threshold current enhances the flexibility of the architecture, making it suitable for different kind of SiPM detectors and applications. An 8-channel ASIC, suitable for the read-out of SiPM arrays has been designed and manufactured following this approach. The characterization of the chip is currently in progress. Here we report the preliminary measurement results obtained by coupling a single channel to a single SiPM detector excited by a pulsed blue LED.","PeriodicalId":246540,"journal":{"name":"2009 3rd International Workshop on Advances in sensors and Interfaces","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131263631","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 advantage of solar energy over other forms of environmental energy is that the available solar power can be predicted with reasonable accuracy allowing the implementation of efficient power management techniques. However accurate predictions of future energy profiles can be expensive in term of memory occupancy and complexity and a trade-off between accuracy and computational effort must be evaluated. In this paper we compare different solar energy prediction algorithms that give estimates future available energy over the time. They are computationally simple and have a small memory footprint to facilitate the implementation in resource limited solar harvesting sensor nodes. Simulation results show that the most effective predictors is possible achieve high accuracy, diverging from real energy profile by less than 10%.","PeriodicalId":246540,"journal":{"name":"2009 3rd International Workshop on Advances in sensors and Interfaces","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115896006","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}

However, monitoring the simultaneous presence of multiple agents in a sample is still a challenging task. Multiple agents may often attach to the same probes on an array which makes it difficult to design a chip that can distinguish such agents (leading to low specificity). Thus, sophisticated algorithms for targets identification need to be implemented in biochip in order to maximize the number of distinguishable targets in the samples. The proposed algorithms are also required to introduce sophisticated signal processing and more intelligence on-chip. Dealing with these new processing and information technology demands constraints also require more innovative approaches towards hybrid integration technologies. To address such new demands, we discuss in this paper an innovative 3D-integrated bio-chips especially dedicated to label-free DNA detection.","PeriodicalId":246540,"journal":{"name":"2009 3rd International Workshop on Advances in sensors and Interfaces","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131195104","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}
