OTFT-based sensing technologies take advantage of the physical or chemical changes taking place in or around the organic semiconducting material when exposed to different analytes in gaseous or aqueous environments. Measurements in electrolytes and complex media relevant for cell analysis have shown that the devices can be directly used as ion-sensitive transducers and are suitable for in vitro biosensing applications. Within the pH range from 6–8 relevant for cell analysis, an almost linear dependence of the device current with the pH has been observed. At room-temperature, ion-sensitivity of e.g. Na+ down to 10–5 M can be easily achieved.","PeriodicalId":201386,"journal":{"name":"2011 IEEE SENSORS Proceedings","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125830395","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}

We claim that capturing events globally, although seems against intuition, can save energy by enabling the organization of effective searching queries. To enable this capability, sensor readings can be combined using electronic switches and therefore enable event detections in groups of sensors with single measurements. We demonstrate this sensing mechanism on a prototype keyboard system made from E-Textile pressure sensors.","PeriodicalId":201386,"journal":{"name":"2011 IEEE SENSORS Proceedings","volume":"599 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123275206","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}

Virtual Machines (VMs) provide a reprogrammable and hardware-independent runtime environment for WSN-based applications but at the expenses of a lower efficiency. On the contrary, code native loaders provide higher computational efficiency but do not support heterogeneous networks and are not able to optimize the code size. In this paper we suggest REEL, a real-time computational-efficient reprogrammable VM-based framework for WSNs. The proposed approach guarantees a higher efficiency compared to traditional VMs and a shorter execution time which, in turn, implies a lower energy consumption. Experimental results on a real application confirm the validity of the proposed solution.","PeriodicalId":201386,"journal":{"name":"2011 IEEE SENSORS Proceedings","volume":"07 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123406394","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 experimental results indicate that the cantilever sensor operated in the second resonant mode exhibits higher quality factor than the fundamental mode, i.e. 2100, implying that a higher sensitivity, i.e. 32.75 Hz/ng, can be attained by operation at higher resonant mode.

As the well performance in dealing with evolving surface, the FMM has been improved and introduced into three-dimensional (3D) lithography simulation of thick photoresists such as SU-8 photoresist. A stationary level set formulation of lithography simulation has been established, and solved at an extremely fast speed. A hash table has been applied to reduce the storage memory of the algorithm by 23% at least without any precision loss.
