Whispering gallery mode (WGM) microresonators have advantages of an ultra-high Q-factors and a mass production capability of a sensor chip. This work presents a variation of WGM spectra depending on each antibody and antigen bound to a polystyrene microsphere, which allowed us to evaluate optically the thickness and the refractive index of the antigen antibody layer from a shift of the WGM spectra peak. Furthermore, the split variation of the WGM spectra peak by the adsorption of the antigen antibody was evaluated by polarization and the excitation position. The split variation of the scattered light peak depended on the direction circumnavigating microsphere.","PeriodicalId":13244,"journal":{"name":"IEEE SENSORS 2014 Proceedings","volume":"14 1","pages":"641-644"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84839034","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 present our latest efforts towards a novel non-invasive wearable sensor system including photoplethysmogram (PPG) and electrocardiogram (ECG) to remotely and continuously monitor vital signs of animals. To overcome the limitations imposed by the dense hair layer, we investigated the use of pointed style electrodes, traditionally used in training (shock) collars, as passive ECG recording electrodes. We also studied the incorporation of light guides and optical fibers for efficient optical coupling to the skin. The ECG and PPG sensors were interfaced to a system on chip (SoC) with Bluetooth capability for transferring the data to a nearby smartphone or computer for data storage and analysis.","PeriodicalId":13244,"journal":{"name":"IEEE SENSORS 2014 Proceedings","volume":"26 1","pages":"2203-2206"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88066481","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}

It has an advantage in that it can be mounted on non-planar surfaces, and, through having a low resistance, it can embed an electrical feed into the COP substrate. Metal film working as a flow sensing element was formed on a thin polyimide membrane produced by sacrificial etching. Flow sensing characteristics, such as the calibration curve and response waveform, were successfully obtained. The relationship between the sensor output and flow rate closely matched the calibration curve derived by King's law. The obtained response times of both rising and falling were 0.50 s and 0.67 s, respectively.","PeriodicalId":13244,"journal":{"name":"IEEE SENSORS 2014 Proceedings","volume":"8 1","pages":"424-427"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90165160","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 two elements array is presented: a central disk and a external ring with centre frequencies of 0.55 and 0.25 MHz, respectively.

The measurement of the temperature distribution has previously only been simulated, as using a standard temperature sensor would inadvertently hamper the flow. This issue can be solved by using a small sized FBG sensor array.

Nanostructured sensors prepared by the Langmuir-Blodgett (LB), Layer by Layer (LbL) or electro-deposition are superior because the high number of active sites. The LB and the LbL techniques can be used to co-deposit electrocatalytic materials to obtain a synergistic electrocatalytic effect. Moreover, LB and LbL can be used to immobilize enzymes in a biomimetic structure formed by amphiphilic lipids. Such sensors show an enhanced selectivity. The presence of phthalocyanines as electron mediators improves the performance of the sensors. Combining sensors and biosensors in the same array provides the advantages of classical phthalocyanine based-sensors, with the specificity of the enzyme-substrate reaction typical of biosensors.
