The availability of information about daily physiological state and activity makes it possible to judge the health condition and provide predictive diagnosis and treatment. A wireless sensing system for monitoring physiological information in the living environment was developed and its functions were evaluated. The system consists of ear-worn temperature sensors, thermo-hygrometers, skin temperature sensors, and an ECG sensor with accelerometer. Data could be obtained in daily life without restraining wearers' movements using multiple networked wearable sensors with a reasonable battery life. The level of data loss in wireless communication was low making it possible to estimate physiological state, even though both the IEEE 802.15.4 radio and the low power radio coexist. The system was evaluated for the prevention of heat stroke and unwellness during exercise monitoring real-time thermal physiological state with ambient temperature and humidity. Experiments showed that the detection of the abnormal level of physiological data and its change was effective in judging the physiological state and giving a warning on the health condition in the context of activity and surroundings.","PeriodicalId":202062,"journal":{"name":"2011 Fifth International Conference on Sensing Technology","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134645974","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}

A model based on independent component analysis was developed to estimate nitrate contamination. The model was tested with eight sets of mixed NH4NO3 and (NH4)2HPO4 water samples. From the results, the model can acceptably detect the presence of nitrate added in distilled water and capable of distinguishing the concentration level in the presence of other type of contamination.

MEMS technology was applied and by etching process 140∼300/40- µm of micro structures were realized easily directly on the elongated and polarized polyvinylidene fluoride (β - PVDF) film that will be used as the sensing element in the skin sensor. The effects of PVDF film etching condition, especially the experienced temperature history to the PVDF important sensing parameter of piezoelectric constant was evaluated by experiment. PVDF film etching characteristics were introduced also. N,N′-dimethyl acetamide (DMA, C4H9NO) solution was used as the wet etching etchant, and O2 gas for the RIE dry etching process. Under the temperature of less than 55 °C , the PVDF film piezoelectric constant was got almost no change, and at the range over 55°C , the constant start to deteriorate linearly according with the temperature rise about 0.3×10−12; (C/N)/°C. At about 100 °C , there was only 50% of deterioration on the PVDF film piezoelectric constant. Such a strong piezoelectric activity will be useful to the sensitivity of the skin sensor. By photo mask design and control of the process condition, much fine and complex micro structure could be fabricated directly on the PVDF film without noticeable degradation of its piezoelectric constant, and it will be useful to realize the required soft and high sensitive, high-resolution skin sensor.","PeriodicalId":202062,"journal":{"name":"2011 Fifth International Conference on Sensing Technology","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127856627","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}
