Since 2011, the “Fast Track Prosthetic Knee Project” at the Clinic Hospital of Barcelona (Spain) includes an educational session as patient empowerment previous to knee arthroplasty surgery. This paper presents a study performed in 41 patients measuring the evolution of emotional stress generated by knee arthroplasty surgical intervention during the educational session. Differences in emotional stress before and after an educational session were analyzed, by using psychometric tests and heart rate variability (HRV) as indicators of stress. Both physiological and psychological measurements suggest the effectiveness of the empowerment session through a higher wellness state of patients, decreasing stress psychometric test value of 45.06% compared to their initial values and increasing the mean HRV 6.08%, with significant p-value (p<;0.0005) of paired samples T-student test, which corroborate that patients have a different stress state before and after the empowerment session. Additionally a Pearson correlation of -0.273 (p=0.02) between these stress indicators confirms that a HRV increase could be associated with less stressed state.","PeriodicalId":296271,"journal":{"name":"2014 IEEE 9th IberoAmerican Congress on Sensors","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127568924","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}

This promotes the development of new monitoring tools, and especially those with outstanding reliability and response time, and nonstationary features. This paper presents the design and implementation of a transportable gas detection and environmental monitoring device. Ideas taken from the Arduino and Lego constructions are kept in mind during the design of the device, looking further facilitate the development of product family of this device; likewise, the use of reconfigurable and interconnectable platforms with open hardware are considered. The transducers have been selected based on their reliability, small size and easy inclusion in an electronic system. Then, was developed a device that supports transducers for environmental gases, such as: carbon monoxide (CO), ozone (O3), volatile organic compounds (VOC), nitrogen dioxide (NO2) and sulfur dioxide (SO2); as well as the possibility to interface with other systems for common gases such as carbon dioxide (CO2) and oxygen (O2) before developed. Other environmental measures such as speed and wind direction, temperature and relative humidity, may also be included. In this case, a configurable platform based on mixed-signal circuits, PSoC5, was used for the development of embedded system. This platform can be interfaced with different Arduino shields and achieves the integration of several analog functions. This system manages, acquires and processes signals from the above transducers. The measurements can be displayed on an LCD display, save into an SD memory and send to the Web using Ethernet interface. The device is hand size, easy to carry and can operate with a battery. Its user interface is simple and provides updated and in-situ readings. Currently, successful results have been obtained from the functional and metrology testing of the manufactured prototype.","PeriodicalId":296271,"journal":{"name":"2014 IEEE 9th IberoAmerican Congress on Sensors","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131166888","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}

PLA can be produced via processing starch, it is mechanically robust and environmentally stable and has therefore attracted interest in applications such as biomedical implants, controlled drug delivery and other kitchen variety commodity products. Making PLA electrically conductive via blending it with conducting polymers will extend its range of applications to include electronic devices and sensors. Commercial PLA has a hard grainy morphology, but is readily soluble in organic solvents and can be cast into thin films, fibers, foams or other forms. A fiber typically has a larger surface area to volume ratio compared to films and is thus technologically advantageous for sensor applications. We have successfully prepared conducting PLA/PANi nanofibers at low PLA concentrations in CHCl3 and used it to sense alcohol vapors of increasing molecular size. The larger the size of the alcohol molecule, the longer it took for the sensor to reach saturation and the sensitivity was smaller. The sensor response times were found to be slower than the recovery times by more than two orders of magnitude for the larger alcohol molecules. Since larger molecules were not able to penetrate the fibers, they were easier to remove. The fiber sensors could be tested on various alcohols without damage and hence were reusable. Conducting PLA based nanofibers therefore present yet another means of fabricating gas sensors and that are biocompatible.","PeriodicalId":296271,"journal":{"name":"2014 IEEE 9th IberoAmerican Congress on Sensors","volume":"2 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131938395","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 polymeric particles show potential capacity to release drugs and compatibility in biological environments. The emulsion/diffusion process is applied to produce these particles, and technologies based on microfluidic provide miniaturization of such process allowing particles with physical and chemical controlled characteristics. Nevertheless, the integrated system of technological devices like sensors, microactuators and controllers is crucial to improve the performance and efficiency of particles production with automatic cycles. The proposal of this work is to develop the integrated system to produce nano/microparticles for drug encapsulation, using microfluidics devices with control and automatic actions in continuous scale. The system is developed through devices integration, system characterization and control loops, using sensors, pumps, microfluidics devices, communication drivers, data acquisition, and control programs. The result of this work is the integrated system to produce particles of size 499-1500 nm with polydispersity index of 0.3 to 0.5 with potential to be used as drug delivery systems. The experimental results were validated by size measurement and polydispersity distribution with optical microscopy, scanning electron microscopy and dynamic light scattering.","PeriodicalId":296271,"journal":{"name":"2014 IEEE 9th IberoAmerican Congress on Sensors","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134396392","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}
